Foreword<br />

Increasingly, biomass is being considered a major source of energy for development.<br />

Until now, energy planners in developing countries have thought<br />

of biofuels as suitable primarily for "traditional" uses, such as domestic cooking<br />

and small-scale rural industries. But even remote regions have felt the<br />

higher costs of 'conventional" fuels - either directly or indirectly - through the<br />

higher prices commanded by cordwood and charcoal. These are the only biofuels<br />

whose quality enables them to substitute readily for oil, kerosene, or coal<br />

in many uses.<br />

Rather than fight the trend to commercialization of biomass, planners in<br />

such countries as the Philippines and Brazil are beginning to see their biofuels<br />

as economically competitive new fuels that canl yield enough energy for vir­<br />

tually any use. In the Philippines, irrigation pumps, electricity generators,<br />

fishing boats, and ice machines are fueled with wood and charcoal. Other<br />

countries are planning similar biomass-based energy programs. Experience<br />

has taught that such programs need a framework as comprehensive as that required<br />

for coal, peat, or any other fossil resource. The development of a complete<br />

bioenergy economy requires the coordination of comparable national<br />

policies and plans, project efforts, and research programs. Once such a<br />

framework is established, informed decisions can be made about managing<br />

the production of biomass materials that can be converted into useful forms of<br />

energy. In many cases the preferred biomass will be woody.<br />

The Agency for International Development (AID) has made the development<br />

of indigenous energy resources, including biomass, a high priority for its<br />

development assistance programs. AID provides t,2chnical assistance and information<br />

to countries interested in systematic approaches to developing their<br />

renewable energy resources. This handbook for identifying existing and<br />

potential fuelwood crops is one example of such efforts to assist those involved<br />

in the development of bioenergy systems. It is intended to complement<br />

Firewood Crops: Shrub and Tree Species for Energy Production, published by the<br />

National Academy of Sciences in 1980, by providing a tool useful in the field<br />

and in the classroom throughout tropical regions.<br />

This book was written under a contract funded by AID and administered by<br />

the Forest Service, U.S. De<strong>part</strong>ment of Agriculture.<br />

How to Use This Handbook<br />

This handbook contains botanical descriptions of 90 tree species. The<br />

species are arranged alphabetically by their commonly accepted scientific<br />

names beginning on page 1,except that ten species of mangrove are at the end<br />

of the list (beginning on page 294).<br />

If only a common name of a specimen is known, consult the Index of Conmon<br />

Names on page 340. This list offers one or more common names by<br />

which the species is known in its natural range of distribution. The commonly<br />

accepted scientific name and page reference are given for each common name<br />

indexed. The specimen can then be compared with the description and illustrations<br />

given.<br />

The Index of Scientific Names, on page 337, lists the botanical or Latin<br />

names, synonyms, and names of plant families. When the scientific name is<br />

known, the reader may refer directly to the section on that species. If the plant<br />

family is recognized, this index can also be consulted for numbers of the pages<br />

describing all its species.<br />

Introduction<br />

The main objective of this handbook is to aid the identification of the common<br />

trees and shrubs grown as fuelwood crops in plantations and forests<br />

chiefly in tropical regions. It is intended as a companion volume to Firewood<br />

Crops: Shrub and Tree Species for Energy Production (National Academy of<br />

Sciences, Washington, D.C., 1980). Sixty woody species were described in<br />

detail and illustrated in Firewood Crops; the collection is expanded to 90<br />

species here.<br />

This book is designed to help in the recognition and naming of growing<br />

plants and specimens through nontechnical botanical descriptions and illustrations<br />

that show details of leaves, flowers, and fruits. Drawings from older<br />

volumes have been assembled for nearly all species. Previously published<br />

distribution maps have been included for many. Additional references, including<br />

classical and newer monographs, are cited as sources for further infornation.<br />

Numerous common names for different languages and countries have<br />

been compiled n.d indexed to assist identification.<br />

Plan of the Text<br />

Information for each species in this book generally follows the plan used in<br />

Firewood Crops. Some subjects have been expanded, and other topics not<br />

related to identification have been condensed or omitted. The botanical<br />

descriptions are similar to those of other publications by the author, especially<br />

the two-volume handbook on the trees of Puerto Rico and the Virgin Islands<br />

(Little and Wadsworth, 1964; Little, Woodbury, and Wadsworth, 1974). Text<br />

and drawings of 30 species from these references have been adapted or revised<br />

here. Throughout, the aim has been to prepare accurate botanical descriptions<br />

in mostly nontechnical terms. The metric system has been used for<br />

measurements. A table for converting to this system is found on the inside<br />

back cover.<br />

Botanical Description<br />

A description and keys to individual species are provided for the 7 genera<br />

which have 3 or roore species described here, and for the group of mangroves.<br />

Next come the species descriptions which include the following information.<br />

The heading above the text of each species gives the accepted scientific<br />

name, a Latin binomial. This scientific name is repeated, with the author<br />

added, as the botanical name; if the author's name is long, it is usually abbreviated.<br />

Next come any synonyms, that is, other widely used scientific names.<br />

These are followed by common names, given by language or country. The<br />

plant family in English and Latin is given last. For the legume family, the subfamily<br />

is added in parentheses.<br />

While scientific names are necessary in international references involving<br />

ix


many countries and languages, common names used locally are important aids<br />

to identification. This compilation sought to expand the list of common names<br />

by languages and countries, as noted in tile publications consulted, and to offer<br />

here tile one preferred in each country. It is impractical to copy all com­<br />

mon names found in print. Because of different groups and dialects, one<br />

some with<br />

species within a large country may have 15 or more local names,<br />

slightly varying spellings and pronunciations. The common names compiled<br />

name first and then others<br />

here by languages and countries list tile preferred<br />

in use, with English names first.<br />

species mentions important details, including<br />

The first paragraph under<br />

the general climatic group<br />

special features for identification or recognition,<br />

botanical description in several<br />

and any unusual values. Then follows tile<br />

paragraphs, with side headings in boldface type. First is a general description,<br />

or deciduous and whether spiny.<br />

including size and habit, whether evergreen<br />

at maturity on good sites, which obviously vary<br />

Sizes generally are averages<br />

for the trunk, crown, bark, twigs,<br />

greatly. Other details are given<br />

and<br />

sometimes buds.<br />

The paragraph on leaves includes such details as arrangement, whether simple<br />

or compound and divided into leaflets, and shape, size, base, tip, margin,<br />

arrangement of veins, surfaces, color, and hairiness.<br />

Discussed under flowers are the flower cluster, shape, size, color, distinctive<br />

characters, and important notes on <strong>part</strong>s. The fruit description includes kind,<br />

shape, size, color, and seeds.<br />

compiled from available sources<br />

A brief description of the wood has been<br />

nearly all species and contains such information as wood anatomy and<br />

for<br />

wood properties. Various uses of the wood, especially as firewood and charcoal,<br />

are summarized.<br />

Paragraphs on other uses include minor forest products, such as bark, edible<br />

fruits and seeds, chemicals, and medicines. Also discussed are uses in cultivation,<br />

such as forest plantations, fuelwood plantations, shade, ornament,<br />

Forage value for liveshelterbelts,<br />

windbreaks, hedges, and erosion control.<br />

stock and wildlife is noted.<br />

native range by connatural<br />

distribution summarizes tile<br />

Information on<br />

tinents and countries along the range border. The altitude range is included.<br />

Discussion of the distribution of introduced species is general and does not list<br />

every country with successful plantations or trials.<br />

climate and soils, including<br />

A brief paragraph containing information on<br />

temperature and rainfall, is condensed from the discussions of environmental<br />

requirements in Firewood Crops. Data on vegetation type and associated trees<br />

are given if known.<br />

Details about named varieties, related species, and derivation of scientific<br />

names are added, when appropriate.<br />

x


Illustrations<br />

Illustrations, including drawings and maps, have been compiled from<br />

various publications. Most of these illustrations are older drawings skillfully<br />

executed from living plants. Most show a leafy twig, flowers, and fruits; many<br />

also have details enlarged. Illustrations for a few species are incomplete.<br />

Because these illustrations comc from many sources and are by different ar.<br />

tists, they vary in style and detail. Some are from early works long out of print.<br />

However, these drawings are still useful for identification today.<br />

Published distribution maps showing natural ranges for 61 species are<br />

reproduced here. A few are from taxonomic monographs. Fifteen for Australia<br />

(most from Hall et al., 1970) show the entire natural range. However, many<br />

show only <strong>part</strong> of the extent within one country or region. Sixteen are for India<br />

and adjacent countries (Pearson and Brown, 1932). Nine are from southern<br />

Africa (Coates Palgrave, 1977). Eight for the United States and 4 for Puerto<br />

Rico are from the author's publications. Though incomplete, these maps may<br />

be useful in indicating seed sources.<br />

References<br />

References, chosen mainly to assist in identification, are cited after the text<br />

describing each species. Firewood Crops lists more titles and publications with<br />

additional information on cultivation, growth, and yield are available for<br />

many species.<br />

Most countries possess technical, often lengthy, descriptive floras, for identification<br />

of seed plants, including trees and shrubs. Many geographical or<br />

political divisions have useful illustrated handbooks for naming common trees<br />

and shrubs. However, these publications generally emphasize the native<br />

species and may not contain recent introductions such as fuelwood crops.<br />

Statistical Summary<br />

The 90 firewood species described and illustrated here are classified in 48<br />

genera and 22 piant families; they thus represent many environments. Thirtyfive<br />

species, more than one-third, belong to the Legume Family, Leguminosae,<br />

including 10 in the genus Acacia, acacia, and 7 in Prosopis, mesquite. The<br />

Myrtle Family, Myrtaceae, has 13 species, of which 10 are in the genus<br />

Eucalyptus, eucalyptus.<br />

The remaining 42 species are distributed Lmong 20 plant families with I to 4<br />

species each. The genus Trema, trema, has 4 species described, while 4 genera<br />

have 3 each: Alnus, alder; Avicennia, black-mangrove; Casuarina,casuarina;<br />

and Pinus, pine.<br />

Conifers, or softwoods, are represented by only the Pine Family, Pinaceae,<br />

with 3 species in the genus Pinus, pine. All the others are hardwoods, or<br />

xi


dicotyledons, but their woods vary widely from hard to soft. Information on<br />

mangroves has been expanded and all species are treated together following<br />

the other genera. Ten species of mangrove in 7 genera and 4 plant families are<br />

described.<br />

trees; most are small to<br />

Nearly all species described in this handbook are<br />

medium in size, but some<br />

become large. A few species in very dry, almost<br />

treeless regions are shrubs that seldom, if ever, attain tree size. One is grown<br />

as an annual crop.<br />

The 90 species may be grouped according to climate, as in FirewoodCrops.<br />

However, the three groups intergrade. Some species are cited in that volume's<br />

more than one group. More<br />

than one-third of the species covered in this handbook (33) are<br />

humid tropics, and one-sixth, or about 15, in tropical highlands. The remaining<br />

42 are in arid and semiarid regions.<br />

ACACIA<br />

Common Names acacia; wattle (Australia)<br />

Legume Family, Leguminosae (Mimosoideae<br />

The 600-800 species of trees and shrubs of the genus Acacia are widely distributed<br />

in tropical and subtropical regions of the world, with Australia and<br />

Africa having the greatest numbers. Acacia, derived from the Greek word for<br />

thorn, is the classical Greek name of a thorny tree of Egypt, thought to be of<br />

this genus. Species of Acacia, especially those with showy flowers, are called<br />

"wattle" in Australia. That term refers to twigs, saplings, or flexible rods<br />

planted or interwoven together in the framework of house walls.<br />

Growing mainly in dry regions, trees and shrubs of this species are mostly<br />

evergreen, often with spreading crown and spines. Twigs are slender, often<br />

with spines paired from stipules (sometimes swollen) or scattered. Leaves are<br />

alternate and crowded, hipinnately compound with many small leaflets; but in<br />

about 300 Australian species there are simple flattened leaves (phyllodes) from<br />

modified leafstalks. Flower clusters are round (heads) or cylindrical (spikes) at<br />

leaf bases. Numerous small flowers are yellow or greenish-white. The calyx is<br />

bell-shaped and mostly 5-toothed; petals, mostly 5, are more or lcss united;<br />

stamens are nunerous, threadlike, and longer than the petals; and the pistil<br />

has a narrow ovary, long slender style, and doi stigma. Fruit isa nearly cylindrical<br />

or oblong, flat pod, not splitting open. The several seeds are beanlike<br />

and flattened.<br />

The l0 species important for firewood described and illustrated here are sep.<br />

arated in the key below.<br />

1. Acacia auriculiformis<br />

Botanical Name Acacia auriculiformisA. Cunn. ex Benth. (also spelled auriculaeformis).<br />

Common Names northern black wattle, earpod wattle, Darwin black<br />

wattle (Australia); akashmoni, Australia babul (India); kasia (Indonesia);<br />

Papua wattle (Papua New Guinea).<br />

Legume Family, Leguminosae (Mimosoideae<br />

This hardy, drought-resistant Australian and Papuan tree can produce good<br />

fuelwood<br />

on poor soils. It is recognized by broad, lance-shaped leathery<br />

phyllodes with several long, parallel veins; many tiny flowers in long, narrow<br />

cylindrical clusters; and flattened pods twisted in an irregular coil or spiral<br />

suggesting an ear. The specific name from Iatin, meaning with the shape of a<br />

small ear, refers to the pods. This is a fuelwood species for the humid tropics.<br />

Description Small to medium-sized deciduous or evergreen tree 8-20 m<br />

high with usually 2 or more, often crooked, trunks up to 60 cm in diameter,<br />

with dense crown, often with large low branches and poor form; on favorable<br />

sites a large tree to 25-30 in. Bark gray or brown, smoothish, becoming rough<br />

and fissured. Twigs slightly angled, mostly hairless.<br />

Leaves alternate, simple flattened<br />

phyllodes (modified leafstalks), lance-<br />

shaped or oblong, slightly curved, long-pointed at both ends, 10-16 cm long,<br />

mostly 1.5-2.5 cm wide, 4-9 times as long as broad, thick, leathery, hairless,<br />

with several long parallel veins (3 prominent) from base, which has a gland,<br />

and many crowded fine veins forming network.<br />

Flower clusters (spikes) 5-8 cm long, paired at leaf bases, narrow. Flowers<br />

many but not crowded, stalkless, tiny, 3 mm long; composed of cuplike,<br />

5-toothed, hairless calyx 1 mm long; corolla of 5 narrow, pointed petals 2 mm<br />

long; many threadlike stamens 3 mm long; and pistil with hairy ovary and<br />

threadlike style.<br />

Pods (legumes) 6-8 cm long, 1-1.5 cm wide, flattened, twisted in irregular<br />

coil or spiral, outer edge often wavy, with prominent veins, hard. Seeds<br />

several, beanlike, elliptical, flattened, 5 mm long, encircled by long threadlike<br />

red or orange stalk.<br />

Wood dark red with yellow sapwood, heavy (sp. gr. 0.6-0.75), very hard,<br />

durable, high calorific value. Good firewood, excellent charcoal that glows<br />

well and burns without smoke or sparks, pulpwood, suitable for construction<br />

and furniture; tannin in bark.<br />

Other Uses Widely grown for ornament and shade because of dense<br />

foliage, hardiness in cities; erosion control on steep, unstable slopes and<br />

beaches; suitable on poor sites for fuelwood and charcoal.<br />

Natural Distribution<br />

Papua New Guinea, islands of the Torres Straight,<br />

and northern Australia in Queensland (Cape York Peninsula) and Northern<br />

Territory (Arnhem Land). Altitude sea level to 500 m.<br />

2. Acacia brachystachya<br />

Botanical Name Acacia brachystachyaBenth.<br />

Common Names umbrella mulga, turpentine mulga, narrowleaf mulga<br />

Legume Family, Leguminosae (Mimosoideae)<br />

Acacia brachystachya is widespread in arid interior Australia. This shrub or<br />

small tree has upright, very narrow phyllodes; tiny flowers in cylindrical<br />

clusters; and very narrow, nearly cylindrical, silvery pods that are hard and<br />

hairy. This fuelwood species for arid and semiarid regions produces superior<br />

firewood. The specific name from Greek, meaning "short spike," refers to the<br />

flower cluster. "Mulga" is the Australian aboriginal name for several species.<br />

tree to 7 m high, evergreen (?),<br />

Description Tall bushy shrub or small<br />

usually branching from base, with spreading rounded crown of upright<br />

branches. Twigs angled, with brown and silvery pressed hairs.<br />

Leaves alternate, simple flattened phyllodes (modified leafstalks), upright,<br />

very narrow (linear), 8-10 cm long, 2-3 mm wide, mostly 30-50 times as long as<br />

wide, slightly flattened, long-pointed, curved, stiff and leathery, with many<br />

fine veins and prominent gland at base.<br />

Flowerclusters (spikes) cylindrical, single at leaf bases, 1.5 cm long, shortstalked.<br />

Flowers many, crowded, stalkless, tiny, 2 mm long, composed of<br />

5-lobed calyx 0.5 mm long, corolla 1.5 mm long, 5-lobed halfway to base, often<br />

finely hairy, many threadlike 2 mm stamens, and pistil with hairy ovary and<br />

threadlike style.<br />

Pods (legumes) long, very narrow (linear), 3-6 cm long, 3-5 mm wide, 2-2.5<br />

mm thick, nearly cylindrical, slightly narrowed between seeds, silvery, finely<br />

hairy, with network of veins, hard, woody. Seeds several, beanlike, elliptical,<br />

flattened, 5-7 mm long, on threadlike twisted stalk.<br />

Wood hard, heavy, durable; superior firewood.<br />

Other Uses Used to manufacture small ornamental objects. Foliage,<br />

as<br />

though of low palatability, sometimes eaten by livestocl:, can serve<br />

emergency fodder. Aborigines ate seeds.<br />

Natural Distribution Widespread in arid and semiarid Australia, from<br />

southwestern Queensland west of central South Australia and cross to the<br />

central coast of Western Australia. Altitude from sea level to about 600 m. Apparently<br />

not widely introduced elsewhere.<br />

Climate and Soils Arid and semiarid tropical and subtropical, with great<br />

temperature extremes from 40-58 0 C, sometimes between OC and 690C. Annual<br />

rainfall mostly 200-300 mm, sometimes to 500 mm; may be long dry<br />

seasons or droughts. Soils laterites, friable clays, loams, and alluvium. Fairly<br />

common in plains, often in dry stony or grav.elly areas.<br />

3. Acacia cambagei<br />

Botanical Name Acacia carnbageiR. T. Baker<br />

Common Names gidgee, gidyea, gidya, stinking wattle<br />

Legume Family, Leguminosae (Mimosoideae)<br />

Gidgee, an Australian tree of very dry areas, is recognized by the grayish or<br />

whitish, narrow, lance-shaped phyllodes with 1-3 main veins; tiny yellow<br />

flowers in balls; long, narrow, flat, straight pods; and a very offensive odor,<br />

especially during or with the approach of rain. The extremely heavy wood is<br />

one of the world's hardest, heaviest timbers and burns with intense heat. It is a<br />

fuelwood species for arid and semiarid regions. The scientific name honors<br />

Richard Hind Cambage (1859-1928), mining surveyor and undersecretary for<br />

mines, New South Wales. An enthusiastic botanist, he studied Acacia seed­<br />

lings and collected specimens showing that this was a dstinct species.<br />

"Gidgee" is the Australian aboriginal name.<br />

Description Handsome small to medium-sized evergreen (?)tree to 10.12<br />

in high, with straight trunk to 30 cm in diameter, and widespreading,<br />

moderately dense crown of gray or whitish evil-smelling foliage; under ex­<br />

treme conditions only 4 m high, with sparse open crown. Bark dark gray or<br />

brown, rough, fibrous, somewhat flaky, deeply furrowed. Twigs slightly<br />

drooping, angled, often with pressed hairs.<br />

Leaves alternate, simple flattened phyllodes (modified leafstalks), lance­<br />

shaped, straight or curved, 5-13 cm<br />

long, 5-10 nun wide, about 6-16 times as<br />

long as wide, flattened, thick and leathery, short-pointed, with 1-3 main veins<br />

and many fine parallel veins not connected, becoming hairless, covered with<br />

grayish-white bloom.<br />

Flower clusters (heads) like balls, mostly 4-10 on stalks along axis (raceme)<br />

to 3 cmilong or on separate stalks at leaf iase. Flowers 15-25, crowded, stalkless,<br />

tiny, 3 mm long, yellow or orange, with unpleasant odor suggesting rotten<br />

onions. Calyx 0.5 mm long with 5 blunt lobes hairy at tip; 5 narrow petals<br />

more than 1 mm long, hairless or slightly hairy; many threadlike stamens 3<br />

mm long; and pistil with hairy ovary and long slender style.<br />

Pods (legumes) long and narrow, 8-13 cm long, 9-12 mn wide, flat, mostly<br />

straight or curved, thin, with coarse<br />

network of veins, hairless, thin-walled.<br />

Seeds several, beanlike, elliptical, 8-9 mm long, on short thread.<br />

Wood dark reddish or almost black, with pale yellow sapwood, extremely<br />

hard and heavy (sp. gr. 1.31, very fine-textured, with interlocked grain, often<br />

with rings and pretty markings; very durable and resistant to termites but<br />

rather difficult to work.<br />

Excellent firewood, burning completely green or dry, leaving thick whitish<br />

or pale gray ash up to 90 percent lime (calcium oxidel. Because of intense heat<br />

of burning, other wood is usually mixed with Acacia cambagei to avoid buckling<br />

of firebars. Charcoal with high ash content.<br />

Often tie dominant tree, especially along streams and in clay depressions<br />

where water collects after rain; forms dense, pure stands or scrub thickets<br />

with interlacing branches, bordering treeless grassland plains.<br />

Very offensive, almost unbearable odor from foliage, especially during or on<br />

approach of wet weather, detectable for kilometers, which foretells approach<br />

of rain. Because of reports that men cutting down a tree just before a rain be.<br />

came very sick, this species should not be planted within 0.2 km of homes or<br />

even greater distances on windward side in areas with summer rains. Odor apparently<br />

keeps livestock from browsi:ig foliage.<br />

Botanical Name Acacia cyclops A. Cunn. ex G. Don (also spelled cyclopis)<br />

Common Names western Australa coastal wattle, coastal wattle, circleeye-seeded<br />

acacia (Australia); rooikrans (South Africa).<br />

Legume Family, Leguminosae (Mimosoideae)<br />

This Australian shrub or small tree of very dry areas is distinguished by the<br />

small, narrowly oblong phyllodes, tiny flowers in balls, and long, narrow, flat,<br />

curved pods. The specific name "cyclops" is from Greek, meaning "roundeyed,"<br />

and apparently refers to the stalk around the seed. In Greek mythology<br />

it was the name of a race of one-eyed giants. Cyclops is also the name of a<br />

genus of tiny, free-swimming copepod crustaceans, known as "water fleas."<br />

Acacia cyclops is a fuelwood species for arid and semiarid regions.<br />

Description Bushy evergreen shrub 2-3 ni high, dense, often with many<br />

stems; or a small tree to 8 in high, with trunk to 20 cm in diameter and<br />

rounded crown; on exposed coasts, a wind-swept, hedgelike dwarf shrub of 50<br />

cm. Twigs slender, angled, hairless.<br />

Leaves alternate, simple flattened phyllodes (modified leafstalks) narrowly<br />

oblong, 4.9 cm long, 5-13 mm wide, nearly straight, blunt with short, hard<br />

point curved to side, tapering to long-pointed base, stiff and leathery, hairless,<br />

with 3-7 main veins from base and 1 tiny gland on upper edge at base, light<br />

green, shiny when young, pointed downward vertically.<br />

Flowerclusters (heads)like balls, 1-3 on short stalks, up to 3 cm long at leaf<br />

bases, 7 mm in diameter. Flowers about 40, crowded, very short-stalked, tiny,<br />

about 3 mm long, composed of tubular 5-toothed hairy calyx, corolla of 5<br />

separate petals, many threadlike stamens, pistil with narrow ovary and long<br />

threadlike style.<br />

Pods (legumes) narrowly oblong, 4-12 cm long, 8-12 mm wide, flattened,<br />

curved or twisted, dark brown, remaining attached. Seeds several, beanlike,<br />

elliptical, flattened, 5 mm long, dark brown, encircled by thick red threadlike<br />

oily stalk.<br />

Wood heavy, producing dense, small firewood pieces of high quality.<br />

Natural Distribution Native of western Australia, found mostly on<br />

coastal sand dunes. Altitude from sea level to 300 m.<br />

Introduced into South Africa for stabilization of coastal dunes, popular there<br />

for firewood. Goats and antelope browse foliage, wildlife eat seeds and their<br />

oily stalk.<br />

Climate and Soils Arid and semiarid subtropical with annual rainfall of<br />

200-800 mam. Monthly mean temperatures from 31 0 C in summer to 5OC in<br />

winter. Apparently there may be slight frosts. Varying soils from sands and<br />

sand dunes to limestone.<br />

Plants hardy but slow-growing, surviving in very dry areas and tolerating<br />

salt spray, salinity, wind, sand blast, and frosts; however, intolerant of shade.<br />

Related Species The scientific and common names of three related<br />

Australian species have been confused. At one time all were classed as<br />

varieties of Acacia decurrens. Their names and distinguishing characters<br />

follow.<br />

-Acacia decurrens Willd. (A. decurrens var. decurrens and var. normalis),<br />

called green wattle (black wattle) or king wattle, native of New South Wales.<br />

Hairless foliage or young shoots slightly hairy. Leaflets long and narrow, 6-10<br />

mm. Bright yellow flowers in late winter. Pods 5-10 cm long, less than 1cm<br />

wide, slightly contracted between seeds.<br />

-Acacia dealbataLink (A.decurrens var. dealbata (Link) Muell.), silver wattle,<br />

native of New South Wales, Tasmania, and Victoria. Small tree to 10 m<br />

high. Hairy foliage silvery gray or whitish from mealy powder. Leaflets 3-6<br />

mm long, without glands along axis. Pale lemon yellow flowers in winter.<br />

Pods more than 1cm broad, not contracted between seeds, whitish. Scientific<br />

name means "white-powdered."<br />

-Acacia mearnsii De Wild. (A. decurrens var. mollis Lindl., A. rnollissima<br />

auct.), black wattle (green wattle). Small to large tree 6-25 m high. Foliage soft,<br />

hairy; young twigs golden yellow, hairy. Leaflets 3 mm long, blunt, shorter<br />

and broader than A. decurrens. Pale yellow flowers in summer (October-<br />

December) in Australia. Pods as in A. decurrens. Bark blackish.<br />

The name Acacia mollissinia, under which this species was known for many<br />

years, is rejected as a synonym of A. pubescens (Vent) Ait. f., a different<br />

Australian shrub. Acacia rnearnsii,the name now accepted, was given in 1925<br />

to a specimen obtained in Kenya in 1909 and thought to be native. Edgar Alexander<br />

Mearns (1856-1916), physician and naturalist of the United States Army,<br />

collected botanical specimens on field trips to Africa with Theodore Roosevelt<br />

in 1909 and 1911-12, along the Mexican border in 1892-94, and in the Philippines<br />

in 1906-07.<br />

This extremely variable species has been divided into<br />

in minor taxonomic characters, such as pods and<br />

subspecies, differing<br />

hairiness, as well as geographic range. For example, ssp. indica (Benth.)<br />

Brenan in India, ssp. nilotica in Egypt, and ssp. kraussiana (Benth.) Brenan in<br />

southern Africa.<br />

Description Small to medium-sized deciduous or nearly evergreen spiny<br />

tree 10 m high with trunk 30 cm in diameter; sometimes to 20 m high and 80<br />

Wood with narrow to wide whitish sapwood and pinkish heartwood turning<br />

reddish-brown with age, generally with darker streaks, moderately heavy to<br />

heavy (sp. gr. 0.80), with grain straight or somewhat twisted, fine-textured<br />

with large to medium-sized pores. Wood hard, strong, tough, durable, difficult<br />

to saw, and resistant to termites. Valuable source of fuel and charcoal; has<br />

been used in locomotives, river stenmers, small industries. Burning charcoal<br />

reportedly emits sparks.<br />

Other Uses Common on dry plains, Acacia nilotica is one of most important<br />

species in social and farm forestry in India, where classed as one of best<br />

fine-textured hardwoods. Used there for carts, farm implements, tool handles,<br />

oars, boat-building, rafters, carving, turnery, mine timbers, railway crossties.<br />

Natural Distribution Extensive in tropical Africa and Asia from South<br />

Africa north to Egypt and from Arabia to Pakistan and India. Altitude from<br />

near sea level to 500 m.<br />

Introduced widely throughout the tropics and bcoming naturalized, such as<br />

in the West Indies. Large areas of forests established in India and Pakistan.<br />

Planted in Africa along the Blue Nile in the Sudan, in the bushveld of Natal<br />

aisd Transvaal, in Zambia and Botswana.<br />

Climate and Soils Arid tropical with low rainfall. Soils vary from alluvial<br />

subject to seasonal flooding and heavy clays to poor rocky sites. Common,<br />

forming nearly pure forests and thickets; or scattered, such as in dry savanna,<br />

woodland, bushveld, river valley scrub, and scrub.<br />

7. Acacia saligna<br />

Botanical Name Acacia saligna (Labill.) H. Wendl.<br />

Synonym Acacia cyanophylla Lindl.<br />

Common Names orange wattle, golden-wreath wattle, willow wattle, blueleaf<br />

wattle, weeping wattle, western Australian wattle (Australia); Port-<br />

Jackson willow (South Africa).<br />

Legume Family, Leguminosae (Mimosoideae)<br />

This bushy shrub or small tree of southwestern Australia has very narrow<br />

phyllodes, tiny bright yellow flowers in balls, and very narrow, flattened,<br />

straight pods slightly narrowed between seeds. It is so variable that it now<br />

comprises two formerly separate species. Vegetation types of this species include<br />

open dry evergreen forest, temperate woodland, and semiarid<br />

woodland.<br />

Several horticultural forms are distinguished, for example, with drooping<br />

branches, upright flower clusters, and phyllodes to 30 cm long. The specific<br />

name, meaning "willowlike," describes the phyllodes.<br />

Extremely rugged and drought-hardj', Acacia saligna is planted for reclaiming<br />

lands as well as for fuel. This fueiwood species grows in arid and<br />

semiarid regions.<br />

Description Dense bushy shrub 2-5 m high, also a small tree of 5-10 m<br />

with short single trunk to 30 cm in diameter or dividing near base into a few<br />

main branches with widespreading crown, evergreen (?). Bark dark gray or<br />

brown, rough, furrowed; on branches and young plants smooth and gray to<br />

red-brown. Twigs slender, finely angled, green, hairless, often drooping, often<br />

flattened and whitish when young.<br />

Leaves alternate, simple flattened phyllodes (modified leafstalks) varying<br />

from very narrow (linear) to lance-shaped, about 10 times as long as wide,<br />

mostly 8.25 cm long and 0.5-2 cm wide (toward base of plant often as large as<br />

20-32 cm long and 4-8 cm wide), straight or slightly curved to side, longpointed<br />

and tapering at both ends, like ribbons, hairless, often drooping, dull<br />

blue-green to whitish, with prominent midvein and many fine side veins.<br />

Large dotlike gland 1-2 mm or more in diameter at base of upper edge of<br />

phyllode.<br />

Flowerclusters (hea ls) like balls, mostly 2-10 (sometimes 1), on stalks along<br />

axis (raceme) to 8 cm lcng at base of leaf, round, bright yellow or deep golden,<br />

7-10 mm in diameter, , Ith many (25-55) crowded tiny flowers, abundant and<br />

showy. Flowers stalkless 3-4 mm long, mostly hairless, composed of calyx 1.5<br />

mm long with conical tue and 5 short rounded lobes often finely hairy on<br />

edge, corolla of 5 narrow long-pointed petals 2-3 mm long, united near base,<br />

many threadlike stamens, and pistil with hairless ovary and slender style.<br />

Pods (legumes) very narrow (linear), mostly 8-12 cm long and 4-6 mm wide,<br />

straight, flattened, with edges slightly thickened, slightly narrowed between<br />

mm long, shiny dark brown to black, on yellowish stalk.<br />

Wood (properties not recorded) used for fuel including charcoal, for fenceposts<br />

and small farm implements; bark yields tannin.<br />

Other Uses<br />

Cultivated extensively in eastern Australia for its horticultural<br />

value; as a rapidly growing ornamental, provides spectacular display of golden<br />

flowers as well as a quick screen. Though attractive for its dense, sometimes<br />

whitish foliage, trees become open-branched and untidy.<br />

Also planted in eastern Australia to stabilize coastal sands after mining and<br />

as source of tannin; naturalized locally. Because of rapid growth and extensive<br />

root system, this extremely rugged tree widely introduced elsewhere to reclaim<br />

barren, eroded hillsides and wastelands and to stabilize sand dunes.<br />

Planted also for windbreaks and along roadsides and seashores.<br />

Foliage and pods eaten fresh or as hay by livestock; bushes can be browsed<br />

heavily without damage. Acidic gum exudes from injured barK.<br />

Natural Distribution Southwestern corner of Western Australia. Altitude<br />

from sea level to 325 m.<br />

Planted and naturalized locally in eastern Australia. Introduced into South<br />

Africa about 1845 to stabilize shifting sand dunes. Now naturalized and<br />

Legume Family, Leguminosae (Mimosoideae)<br />

Gum-arabic tree, native of Africa, is easily recognized by the short spines or<br />

thorns mostly in 3's. It has small, bipinnately compound leaves; small white<br />

flowers in narrow cylindrical clusters; and broad, flat, papery pods. The<br />

hardy, drought-resistant trees produce gum arabic and good fuelwood and are<br />

widely planted for sand dune fixation and wind-erosion control. This is a fuelwood<br />

species for arid and semiarid regions.<br />

Description Small deciduous spiny tree 6 in high, sometimes to 13 m,<br />

with crown becoming flattened, with deep and widespreading roots; also a<br />

thicket-forming shrub of 3 m. Trunk short, usually branched near base, to 50<br />

cm in diameter. Bark pale brown or gray, becoming furrowed and scaly; slash<br />

mottled red and white. Twigs with yellowish bark, soon peeling off. Short<br />

spines or thorns mostly in 3's at swollen nodes (sometimes only 1), 3-7 mm<br />

long; central spine sharply curved backward, lateral ones straight and pointing<br />

forward.<br />

Leaves alternate, bipinnately compound, 2-6 cm long, with 3-6 pairs of side<br />

axes (pinnae) 2-3 cm long. Leaflets 8-18 pairs on each side axis, narrowly<br />

oblong, small, 3-7 mm long, blunt or short-pointed, gray-green, hairless.<br />

Flowerclusters (spikes) 1-2 at nodes mostly before leaves and longer (2-10<br />

cm), cylindrical. Flowers many, crowded, stalkless, fragrant, 6-8 mm long,<br />

composed of 5-toothed calyx 2-3 mm long, 5-lobed white corolla 3-4 mm long,<br />

many threadlike stamens, and pistil with narrow ovary and threadlike style.<br />

Pods (legumes) short-stalked, oblong, flat, 4-10 cm long, 15-22 mm broad,<br />

sometimes slightly narrowed between seeds, pale brown, papery with prominent<br />

network, fine hairs. Seeds few, round, flat, 6-10 mm in diameter, brown.<br />

Seed crops varying from infrequent to abundant every year.<br />

Wood whitish, hard, heavy. Locally the best firewood and main species for<br />

charcoal.<br />

Other Uses Trunks and roots used for poles, fenceposts, local construc­<br />

tion, tool hanoles, weavers' shuttles. Wood could serve in cabinetmaking.<br />

Ropes nmade from strong fibers of the long surface roots.<br />

Gum arabic, perhaps the most commercially important natural gum, produced<br />

by wounds in trunk and branches mostly of this species, both wild trees<br />

and plantations. Yellowish, odorless, bland-tasting gum in commerce more<br />

tortilis (Senegal); kandili, bisaw (Niger); seyal, sayyal (Arabic); mgunga (Tanzania);<br />

Israeli babool (India).<br />

Legume Family, Leguminosae (Mimosoideae}<br />

This tree or shrub, one of the most widespread species of Acacia in Africa<br />

and the Middle East, is recognized by paired spines of 2 kinds, both -hortcurved<br />

and long-straight, small bipinnately compound leaves, white to pale<br />

yellow flowers in ball clusters, and pods curved and twisted, often in a spiral.<br />

It is drought-resistant and produces superior firewood and charcoal. The<br />

scientific name, meaning "twisted," describes the pods. The common name<br />

"haak-en-steek" means "hook-and-prick" in reference to the 2 kinds of spines of<br />

this fuelwood species for arid and semiarid regions.<br />

Description Small to medium-sized spiny deciduous or nearly evergreen<br />

tree mostly 4-15 m high (rarely 20 m), with trunk branching low; sometimes<br />

with several spreading crooked trunks 20 cm or more in diameter. Small trees<br />

with rounded crown, larger trees with widespreading flat-topped crown suggesting<br />

an umbrella, of dense, fine feathery foliage. Under extreme aridity, a<br />

low shrub of Im; under heavy grazing, reduced to trailing, seemingly unconnected<br />

branches radiating from a low sand mound. Produces long lateral roots.<br />

Bark gray or dark brown to blackish, rough, deeply furrowed, scaly. Twigs<br />

gray-green to reddish-brown, mostly hairy. Spines from stipules paired at<br />

nodes, of 2 kinds with both often on same twig; curved or hooked, brownish,<br />

mostly under 5 mm long, others long-straight and white, 1-5(-9) cm long.<br />

Leaves 2-6 at a node, bipinnately compound, small, 15-35 mm long, with<br />

4-10 pairs of side axes (pinnae) 5-10 mm long, each bearing 7-15 pairs of<br />

Fig. 18. Distribution of Acacia tortilis in southern Africa (Coates Palgrave 1977).<br />

Natural Distribution Extensive through Africa from southern <strong>part</strong> of<br />

continent to tropical Sudan and Ethiopia and the Middle East to Israel, Saudi<br />

Arabia, Yemen. Altitude lowland. Planted in other areas such as India on a<br />

large scale for fuelwood.<br />

Climate and Soils Arid or semidesert tropical, hot and dry, with long irregular<br />

dry seasons. Annual rainfall 100-1000 mm. Maximum temperatures<br />

about 50*C, minimum may be near 0°C. Soils various, including sand dunes,<br />

sands, sandy loam, rocky, and alkaline. In shallow soil, plants shrubby but<br />

develop long lateral roots.<br />

Common in dry savannas, forming groves, and in other types such as<br />

bushlands, thornbush, bushveld, lowveld. The last woody species bordering<br />

the desert.<br />

Extremely hardy and drought-resistant, this species can be grown under<br />

severe arid conditions. Growth slow but relatively fast for dry zone tree.<br />

Young plants not frost-hardy. Because of long lateral roots, plants can spread<br />

to nearby fields and roads, becoming undesirable weeds. If introduced into a<br />

humid climate, could become a serious pest.<br />

Subspecies Species has 4 distinct subspecies (earlier named as species)<br />

with different geographical ranges and different ecological zones and<br />

tolerances. Thus, subspecies or geographical source should be considered<br />

when seed is selected for plantations. These 4 subspecies are listed below wi n.<br />

their ranges and taxonomic differences.<br />

-Ssp. tortilis. Young twigs and leaf axes hairy; pods narrow, hairy, not<br />

glandular, 3-5 mm wide. Egypt and Middle East to Palestine, Yemen, Arabia.<br />

-Ssp. raddiana (Savi) Brenan (AcaciaraddianaSavi). Twigs, leaves, and pods<br />

hairless or hairy; pods mostly hairless, not glandular, 6-9 mm wide. North<br />

Botanical Name Adhatoda zeylanica Medic.<br />

Synonyms Adhatoda vasica (L.), Nees, Justicia adhatodaL.<br />

Common Names vasaka, arusha, bakas, adadodai, adulsa, adusa (India);<br />

adathoda (Sri Lanka); Malabar-nuttree.<br />

Acanth Family, Acanthaceae<br />

This thicket-forming, ill-smelling shrub has large opposite elliptical leaves<br />

and clusters of large, tubular, whitish flowers. It is hardy in semiarid tropical<br />

regions, fast-growing, and unpalatable to livestock. Where wild, it is readily<br />

available as firewood, though in small sizes.<br />

This species is suitable for<br />

reclaiming waste lands. It is propagated from seeds and cuttings and coppices<br />

well. However, the plants could become undesirable weeds where introduced.<br />

Adhatoda is from a local name in India, while zelanica refers to Ceylon,<br />

now Sri Lanka. The genus Adhatoda, with about 20 species in tropical Africa<br />

and Asia, is also united underJusticia.Adhatoda zeylanica is listed as Adhatoda<br />

vasica under arid and semiarid regions in Firewood Crops.<br />

Description Many-branched, dense evergreen large shrub mostly less<br />

than 2.5 m high (sometimes to 6 in), branching from base, with stems less than<br />

3 cm in diameter and large deep roots; very bitter throughout. Twigs enlarged<br />

above ringed nodes, finely hairy when young.<br />

Leaves opposite, elliptical, 10-20 cm long, 2.5-7 cm wide, long-pointed, not<br />

toothed on edges, with many prominent curved side veins, bright green and<br />

hairless above, paler and finely hairy underneath; unpleasant odor when<br />

crushed. Leafstalk 2-3 cm long.<br />

Flower clusters (spikes) sev,:ral upright on long stalks near ends of twigs,<br />

4-10 cm long, compact, with large elliptical, hairy leaflike bracts 2.5-4 cm<br />

long. Flowers several, compact, stalkless, large, 2-4 cm long, composed of<br />

deeply 5-lobed calyx<br />

1 cm long; corolla irregular, tubular, funnel-shaped,<br />

2-lipped, upper lip fringed, hairy on outer sturface, white with purplish spots<br />

and streaks; stamens 2, inserted near throat of corolla; and pistil with narrow<br />

2-celled ovary, 2 ovules in each cell, long style, and stigma slightly 2-lobed.<br />

Fruita stalked club-shaped capsule 2 cm long, hairy, 2-celled, splitting or<br />

exploding in 2 <strong>part</strong>s to release seeds. Seeds 2-4, 7 mm in diameter, wrinkled.<br />

Wood whitish, with very small scattered pores, moderately hard. Used for<br />

firewood, charcoal, gunpowder charcoal; good for quick, intense, long-lasting,<br />

clean cooking fires; burns with little or no smoke, odor, or sparks. However,<br />

only small pieces of firewood available because plants are small.<br />

Other Uses<br />

Leaves, flowers, fruits, and roots long used medicinally in<br />

India for home remedies. Drug vasaka from fresh or dried leaves used chiefly<br />

as expectorant. An alkaloid vasicine and an essential oil found in leaves.<br />

Species apparently toxic to other forms of life; has served in insecticides and<br />

fungicides and as an antiseptic. Termites, fleas, mosquitoes, other noxious intoxic<br />

to coldsects<br />

destroyed by an infusion of leaves. Alkaloid vasicine<br />

blooded animals such as fish but not mammals. As herbicide, leaves prevent<br />

growth of lower aquatics in rice fields, serve also as green manure.<br />

In packing and storing fruits, layers of leaves speed ripening and coloring,<br />

inhibit fungi, repel insects. With boiling, leaves yield yellow dye for coarse<br />

cloth and skins; also special black hue in pottery.<br />

Natural Distribution Common throughout plains and submontane India;<br />

also Pakistan, Nepal, Sri Lanka, Burma, Malaysia. To 1500 m altitude in<br />

12. Ailanthus altissima<br />

Botanical Name Ailanthus altissima (Mill.) Swingle<br />

Synonym Ailanthus glandulosa Desf.<br />

Common Names ailanthus, tree-of.heaven, China-sumac (English); waliyati<br />

drawa (Pakistan); shin-ju (Okinawa; drbol del cielo (Spanish); Gltterbaum<br />

(German).<br />

Quassla Family, Simaroubaceae<br />

com-<br />

Ailanthus has coarse, ill-smelling foliage with very large, pinnately<br />

pound leaves. The broadly lance.shaped leaflets have 2-5 teeth near a I-sided<br />

base; each tooth has a gland-dot beneath. It is fast-growing and hardy in cities,<br />

even where all other trees fail. As a weed tree, it is available for firewood. A<br />

temperate zone tree, it also merits testing in tropical highlands.<br />

This species is easily grown from seeds, which are bone abundantly, and<br />

from root cuttings of either sex. Male trees may be preferred for the absence of<br />

fruits and seeds but have unpleasant flower odor. Female trees have ornamental<br />

fruits, such as one red-fruited variety, but their abundant seeds and seedlings<br />

may be objectionable. The trees form thickets along fences and roadbecome<br />

serious<br />

sides, in abandoned fields, and at forest borders. They can<br />

pests and bad weeds, spreading profusely from root suckers to fields. Eradication<br />

may be difficult.<br />

Ailanthus is from the Moluccan name meaning "tree-of-heaven" and refers to<br />

the height of the tree. The Latin specific name means "very tall."<br />

The genus Ailanthus has about 10 species of tall deciduous trees native in<br />

eastern Asia, East Indies, Philippine Islands, Solomon Islands, and Australia.<br />

Besides the 2 species described here, 2 others of southeastern Asia merit consideration<br />

for firewood plantations: Ailanthus grandisPrain and Ailanthusmala.<br />

Quassia Family, Simaroubaceae<br />

This tropical relative of Ailanthus altissima is similar to that species and<br />

adapted to semiarid as well as humid regions. It is recognized by the large pinnately<br />

compound leaves with many pairs of coat sely toothed, gland-hairy leaflets<br />

and by the many narrow, flattened red fruits. As a fast-growing weed tree,<br />

it is readily available for fuel. The trees, which are easily propagated by seed<br />

and cuttings, grow very fast and coppice well.<br />

Description Handsome, large deciduous tree 18-25 m high, with straight<br />

trunk 60-80 cm in diameter. Bark light gray and smooth, becoming gray-brown<br />

and rough on large trees, aromatic, slightly bitter. Twigs stout, greenish.<br />

Leaves alternate, pinnately compound, large, 30-60<br />

cm or more in length.<br />

Leaflets 8-14 or more pairs, long-stalked, ovate or broadly lance-shaped from<br />

verl unequal base, 6-10 cm long, 3-5 cm wide, often curved, long-pointed,<br />

gland-hairy, edges coarsely toothed and often lobed.<br />

Flowerclusters (panicles) drooping at leaf bases, shorter than leaves, much<br />

branched. Flowers many, mostly male and female on different trees, short­<br />

stalked, greenish-yellow. Calyx 5-lobed, 5 narrow petals spreading 6 mm<br />

across, 10 stamens, and on other flowers 2-5 separate pistils each with elliptical<br />

ovary, 1ovule, and slender style.<br />

Fruits (samaras) many, 2-5 from a flower, lance-shaped, flat, pointed at<br />

ends, 5 cm long, 1cm wide, copper-red, strongly veined, twisted at base. Seed<br />

1, flat.<br />

Wood white and lustrous, turning light grayish-white, without distinct<br />

heartwood, with rather rough feel, soft, very lightweight (sp. gr. 0.45),<br />

buoyant, straight-grained, fairly even and very coarse-textured, with wide<br />

rays, diffuse-porous, growth rings indistinct or none. Easily worked but<br />

perishable and subject to insect attack and stain.<br />

Other Uses In addition to fuelwood, species used for boxes, crates, fishing<br />

floats, toys, tool handles, matches, drums. Yields a gum, which is not used.<br />

Bark and leaves used in home remedies. Lopped branches excellent fodder for<br />

sheep and goats. Trees serve as shelterbelts along borders of fields. Often<br />

planted for fodder, but leaves of young plants not browsed by cattle because of<br />

acrid juice.<br />

Natural Distribution<br />

Common in central and southern India, especially<br />

on old village sites within forests.<br />

Botanical Name Albizia falcataria (L.) Fosb.<br />

Synonyms Albizia moluccana Miq., Albizia falcata (L.) Backer (in <strong>part</strong>) (also<br />

spelled Albizzia)<br />

Common Names Molucca albizia, Indonesia albizia, white albizia (Englishi;<br />

kayu macis (Sarawak, Malaysia); djeungdjing, sengon, sengon laut<br />

(Indonesia); tamalini (W. Samoa); vaivai (Fiji); sau, puah.<br />

Legume Family, Leguminosac (Mimosoideae)<br />

Albizia falcataria, one of the fastest-growing trees in the world, is a fuelwood<br />

species for the humid tropics. It is a large deciduous tree with a thin, very<br />

broad crown of dull green foliage, bipinnately compound leaves with numerous<br />

small, oblong leaflets, and narrow, flat brown pods that split open. It is<br />

widely planted in tropical countries and becoming naturalized.<br />

This pioneer, light-requiring tree produces abundant seeds in lightweight<br />

pods blown by winds. It spreads into clearings and has become established in<br />

abandoned sugar cane fields in Hawaii.<br />

Growth records of this "miracle tree" on good soil and high rainfall are as<br />

much as 7 m in height in little more than a year, 13-18 m in 3years, 21 m in 4<br />

years, and 30 m in 9-10 years. Then growth slows to a maximum of 45 m and<br />

short life of about 25 ,ears. In plots, the most vigorous trees increased in trunk<br />

diameter about 5-7 cm per year. A height of 15 m and diameter of 30 cm have<br />

been attained after 4 years, in Hawaii. The state champion tree in Hawaii<br />

measured 33.6 m high. 9.1 m in circumference at breast height, and 50.9 m in<br />

crown spread.<br />

The trees coppice vigorously and can be harvested in plantations on an<br />

8-year cycle from coppice growth. They are shallow-rooted and very susceptible<br />

to uprooting and breakage of branches by typhoons.<br />

The specific name, "falcate" or "curved like a sickle," refers to the leaflets.<br />

Description Large deciduous tree to 24-30 m tall, with long trunk, often<br />

bent or branching, to 80 cm in diameter, not enlarged at base; thin, very broad<br />

spreading crown, often umbrella-shaped, of dull green foliage. Bark light<br />

gray, smooth with corky warts, showy; inner bark pink, astringent, slightly<br />

bitter. Twigs stout, light gray.<br />

Leaves alternate, bipinnately compound, 23-30 cm long, with tiny rusty<br />

pressed hairs and slender angled axis bearing gla:'d above base. Side axes (pinnae)<br />

10-12 pairs, 5-10 cm long. Leaflets paired, 15-20 pairs on each axis,<br />

stalkless, small, oblong, 6-12 mm long, 3-5 mm wide, short-pointed at tip,<br />

unequal-sided and blunt at base, edges not toothed, upper surface dull green<br />

and hairless, underneath paler and finely hairy.<br />

Flower clusters (panicles) large, lateral, branched, 20-25 cm long. Flowers<br />

many, clustered, stalkless, 12 mm long, whitish, composed of light green bell-<br />

Albizia lebbeh is recognized by its large, bipinnately compound leaves with<br />

large, oblong leaflets rounded at both ends and by the numerous strawcolored,<br />

flat papery pods that hang down and rattle with the wind. This<br />

species is widely planted and available for firewood in arid and semiarid<br />

regions and in the humid tropics. The trees grow moderately fast and coppice<br />

fairly well. The brittle branches may be broken by strong winds, and trees<br />

with roots near the surface are not wind-firm.<br />

This genus contains 100-150 species in the Old World. The name honors<br />

Cavalier Filippo degl' Albizzi, of an old and noble Italian family, who introduced<br />

plants into Europe in 1749. "Lebbek"is the Arabic common name. The<br />

peculiar rattling sound produced by continual movement of the dry pods is the<br />

source of the common names "woman's-tongue," "lengua de mujer," and<br />

"m~tsico."<br />

Description Medium-sized deciduous tree 6-12 m high with trunk often<br />

short, 50 cm in diameter, sometimes a large tree to 30 m tall and 1 m in<br />

diameter, with spreading umbrella-shaped crown of thin foliage. Bark gray,<br />

smoothish, becoming fissured or rough; inner bark pink and bitter. Twigs<br />

greenish, becoming gray or brown, finely hairy when young.<br />

Leaves alternate, bipinnately compound, 15-40 cm long, with greenish or<br />

yellow-brown axis bearing small elliptical gland on upper side near base and<br />

2-4 pairs of lateral axes (pinnae), each with 4-10 pairs of leaflets. Leaflets very<br />

short-stalked, oblong, 2-3 cm long, 1-1.5 cm wide, rounded at both ends and<br />

very unequal-sided at base, with midvein not in center, edges not toothed,<br />

thin, dull green upper surface, sometimes finely hairy underneath; end<br />

leaflets broadest above middle (obovate).<br />

Flowerclusters (umbels or heads) 1-4 rounded masses at end of stalk, 4-10<br />

cm long at leaf base, 5-7.5 cm across; many threadlike, spreading, whitish to<br />

yellow stamens tipped with light green. Flowers many, fragrant, on short<br />

ALNUS<br />

Common Names alder (English); aliso (Spanish)<br />

Birch Family, Betulaceae<br />

The genus Alnus (from the classical Latin name) has about 30 species of<br />

shrubs and trees in the northern temperate zone. They are widely distributed<br />

through the northernmost forests even beyond the limit of trees and extend<br />

southward into tropical mountains to Malaya and Assam and Algeria, and<br />

down the Andes to Peru and Bolivia. They are mainly in wet soils along<br />

streams and in swamps and also as pioneers on exposed soils. The bark is gray<br />

and smooth. Twigs have a 3-angled pith and stalked buds. Leaves are alternate<br />

in 3 rows and are ovate or elliptical with toothed edges. Male and female<br />

flowers occur in separate clusters on the same twig. Male flower clusters are<br />

short, upright cones containing many tiny male flowers. Conelike female<br />

clusters are also short and upright and contain many tiny female flowers.<br />

There are several upright, conelike, dark brown fruits which are hard and eggshaped.<br />

They remain attached and contain many tiny 2-winged nutlets.<br />

Alders are nitrogen-fixing; that is, their roots bear nodules or swellings with<br />

microorganisms that enrich the soil as do legumes. Thus, they are well<br />

adapted to reforestation and soil fertility improvement. The extensive lateral<br />

root system bearing the nodules serves also for watershed protection and erosion<br />

control on unstable slopes. These trees are suitable for planting for fuelwood<br />

in tropical highlands.<br />

This species, native in New World tropical mountains, has 3.6 fruits in a<br />

cluster and ovate leaves doubly saw.toothed with teeth of 2 sizes.<br />

stream banks,<br />

Characteristic of montane forests in valleys, ravines, and<br />

Alnus acuminatais also found on steep slopes and exposed or denuded areas. It<br />

forms secondary forests on landslides and clearings and in pastures and along<br />

roadsides. The species is often found with Pinusand Quercus in Mexico, and in<br />

pure stands or groves called "alisares" in Argentina.<br />

As pioneers the fast-growing plants form thickets on bare, exposed soil. The<br />

small winged nutlets &rseeds are easily spread by the wind.<br />

This species is well adapted to fuelwood production on pasture lands, where<br />

are grazed under scattered G,wide-spaced trees. It is reported that<br />

livestock<br />

forage production increases in pastures where Ahaus acurninatais planted. This<br />

is a fuelwood species for tropical highlands.<br />

18. Alnus rubra<br />

Botanical Name Alnus rubra Bong.<br />

Synonym Alnus oregona Nutt.<br />

Common Names red alder, Oregon alder, Pacific Coast alder, western<br />

alder (English); aune de i'Ordgon (French).<br />

Birch Family, Betulaceae<br />

Alnus rubra, which ranges north to southeastern Alaska, is probably the<br />

northernmost species described here. This leading hardwood of the Pacific<br />

Northwest is a good fuelwood and is considered a fuel source for generating<br />

electricity. It is recognized by the upright, conelike fruits in clusters of 4 to 8<br />

and wavy-lobed leaves with double sz;."-eth and edges turned under. The tree<br />

is a fuelwood species for tropical highlat ds and the humid temperate zone.<br />

This species is one of the most common broadleaf trees or hardwoods within<br />

its range. It occurs in nearly pure stands as the red aider forest type and as a<br />

minor component in the Stika spruce and Sitka spruce-western hemlock types,<br />

and occasionally in others. Pure stands are mainly at lower altitudes in stream<br />

bottoms, moist flats, and lower slopes. Alnus rubra is also found along beaches<br />

where rivers enter the ocean and in swamps. As a pioneer on exposed mineral<br />

soil, it invades landslides, clearings, cutover and burned forest lands, and<br />

roadsides, and forms thickets or pure stands. The fast-growing pioneer plants<br />

can compete with weeds. Their wide-spreading shallow roots have nodules or<br />

swellings containing microorganisms that fix atmospheric nitrogen and thus<br />

enrich mineral soils.<br />

Both scientific and common names refer to the wood, which turns reddishbrown.<br />

Description Small to large deciduous tree 12-30 m high (reported to reach<br />

40 in), with straight trunk 30-80 cm (to 1 m) in diameter and narrow crown of<br />

dark green foliage; with bi ,adiy conical crown down nearly to ground in open<br />

areas. Bark light gray, mottled with white, thin, smooth or becoming slightly<br />

scaly and furrowed into irregular flat plates; inner bark reddish-brown. Twigs<br />

slender, light green and hairy when young, becoming dark red; pith 3-angled.<br />

Winter buds stalked, elliptical, to Icm long, short-pointed, dark red, covered<br />

by 2 hairy scales meeting along edges.<br />

Leaves alternate in 3 rows, ovate or elliptical, 6-13 cm long, 4-7.5 cm wide,<br />

short-pointed at both ends, edges shallowly wavy-lobed with coarse double<br />

sawteeth having both large and small gland-tipped teeth, turned under, slightly<br />

thickened, with 9-15 nearly straight parallel veins on each side of midvein,<br />

upper surface green, nearly hairless and dull to slightly shiny, underneath<br />

gray-green with rusty hairs along veins, remaining green and shedding in late<br />

auti. nn. Leafstalks 7-30 mm long, hairy, glandular.<br />

Flower clustersnarrowly cylindrical, with many dark red scales, male and<br />

female separate on same twig from buds of previous season, opening in early<br />

Wood used for domestic firewood and makes good charcoal. Because of<br />

its rapid growth, species being considered as a potential energy crop to generate<br />

electricity.<br />

Other Uses Red alder an important pulpwood, usually blended with conifer<br />

pulps. Also used in furniture, plywood, woodenware and novelties, paneling<br />

and other millwork, fixtures, tool handles. This species has been cultivated for<br />

ornament and windbreaks and planted on coal mine spoils.<br />

(India); dawu, vellai-naga (Sri Lanka); guediane (Senegal).<br />

Combretum Family, Combretaceae<br />

This hardy tree common in dry forests of India has broadly elliptical leaves,<br />

many small yellow or pinkish flowers, fruits in rounded clusters at leaf bases,<br />

and smooth whitish or gray bark. The wood is readily accessible for fuel and<br />

charcoal. It is a fuelwood species for arid and semiarid regions and also the<br />

humid tropics. This is a dominant species in the dry deciduous or monsoon<br />

forests. The trees are hardy on poor, dry sites but grow slowly. They may remain<br />

dwarfed on exposed rocky slopes and may die back in extreme droughts.<br />

The tropical genus Anogeissus has about 11 species ranging from Africa to<br />

Arabia, India, and southeastern Asia.<br />

Description Medium to large deciduous tree 20 m high, 60 cm (to 1m) in<br />

trunk diameter, sometimes larger; in dry areas a small tree of 5 m or large<br />

shrub. Bark smooth, whitish or gray, hard, shiny, conspicuous; inner bark<br />

red-brown. Twigs slender, hairless.<br />

Leaves alternate, broadly elliptical, 6-10 cm long, 4-6 cm wide, blunt or<br />

short-pointed at tip, rounded or notched at base, edges not toothed, becoming<br />

hairless, side veins slightly curved and sunken, with many fine veins in network,<br />

turning coppery or reddish before shedding in autumn; leafstalk 1-2 cm<br />

long.<br />

Flower clusters (heads) rounded, single or in short clusters (cymes), 1-1.5<br />

cm in diameter, short-stalked at leaf bases. Flowers many, stalkless, 5-7 mm<br />

long, composed of narrow finely hairy tube (hypanthium), calyx with tube and<br />

5 lobes turned back, yellow or pinkish-yellow; no corolla; 10 stamens inserted<br />

on tube; pistil with inferior -celled ovary, 2 ovules, slender style.<br />

Fruits (multiple) many, in rounded clusters (heads) 1cm in diameter. Individual<br />

fruit about 5 mm long, dry, pinkish to yellowish, almost hairless,<br />

1-seeded, flattened with 2 wings and long point from calyx.<br />

Wood with wide, yellowish-gray sapwood and purplish-brown heartwood,<br />

heavy to very heavy (sp. gr. 0.94), fine-textured, with shallowly interlocked<br />

grain, small pores, growth rings present but not distinct. Strong, elastic, very<br />

tough, hard, difficult to season, somewhat difficult to saw but good for turning<br />

and machining, polishes well with smooth shiny surface. Attacked by termites<br />

and not durable in exposed situations. A fine firewood and excellent for charcoal.<br />

Other Uses Widely used for poles, rafters, farm implements, tool handles,<br />

shaft. and axles of carts; also construction, furniture, mine props. Also a possible<br />

kohomba, vcmpu (Sri Lanka); tamaka (Burma); mambu, sadu (Malaysia);<br />

mindi (Indonesia); maranggo.<br />

Mahogany Family, Meliateae<br />

Neem has been called "that most ubiquitous of all plantation trees in arid<br />

regions." Neem plants have fairly rapid growth, coppice freely, and produce<br />

root sprouts from an extensive root system. They are drought-resistant but not<br />

frost-hardy, <strong>part</strong>icularly when young. The generic name means "noble tree" in<br />

Persian, and the specific name refers to India. This genus has a second species<br />

from Borneo to the Philippines.<br />

The species is recognized by the drooping, large, pinnately compound leaves<br />

with many paired, curved, lance-shaped, very long-pointed leaflets, and abundant<br />

small, whitish, fragrant flowers. The wood from plantations is valued not<br />

only for fuel but for construction and furniture. This is a fuelwood crop for<br />

arid and semiarid regions and the humid tropics.<br />

Description Medium to large handsome tree 10-15 m high, with straight<br />

short trunk 30-80 cm in diameter and widespreading branches forming dense,<br />

rounded crown, usually evergreen except in periods of extreme drought, deeprooted.<br />

Bark gray, with scaly plates, thick; inner bark pink, astringent, bitter.<br />

Twigs stout, brown, hairless, twigs and crushed foliage with slight odor of<br />

garlic.<br />

Leaves crowded near ends of twigs, alternate, pinnately compound, 20-35<br />

cm or more in length, hairless, with slender light green axis. Leaflets mostly<br />

I at end often lacking, with stalks less<br />

9-17 (sometimes more), paired except<br />

than 3 mm long, curved lance-shaped with very long point, base blunt and<br />

very unequal or 1-sided, sawtoothed on edges, midvein curved and near lower<br />

edge, 4-8 cm long, 12-22 mm wide, thin, dull green above, paler underneath.<br />

or beck of leaves, 10-30<br />

Flower clusters (panicles) from base of old leaves<br />

cm long, narrow, branched. Flowers many, short-stalked, small, white,<br />

fragrant, 1cm across, composed of 5 rounded light green calyx lobes, 5 oblong,<br />

rounded white petals 5 mm long, 10 stamens united within a tube toothed at<br />

end, and pistil with rounded 3-celled ovary, slender style, and 3-lobed stigma.<br />

Fruits (drupes) many, oblong, 13-20 mm long, light yellow turning purple,<br />

with bitter pulp, large elliptical stone, I large seed.<br />

Wood with grayish-white sapwood and heartwood red, fading to reddishbrown,<br />

aromatic, moderately heavy (sp. gr. 0.56-0.85), hard, with interlocked<br />

Most <strong>part</strong>s of tree yield commercial by-products. Nearly all par:s except<br />

wood used in home remedies or medicine, for example, bark, young fruit, oil,<br />

flowers, leaves, sap, and gum. Bark has high tannin content. Neem oil or<br />

margosa oil from seeds has served in soaps, disinfectants, drugs, cosmetics,<br />

and as a lubricant and fuel for lamps. Seed cake or residue left after oil extraction<br />

reportedly an excellerit fertilizer.<br />

Seeds and leaves yield azadirachtin, apromising new insect repellent. Dried<br />

leaves long used to protect cloth and books from insects. Leaves and twigs<br />

have served as a mulch and green manure fertilizer. In Asia leaves browsed as<br />

fodder, but foliage of the variation in West Africa not eaten by livestock. Twigs<br />

chewed for mouth hygiene, and a toothpaste from the bark extract has been<br />

patented.<br />

Botanical Name Byrsonima crassifolia (L.) H.B.K.<br />

Common Names nance, craboo, crapoo, doncela; maricao cimarr6n,<br />

peralejo (Puerto Rico); nanche, chi (Mexico); nance, nancite (Central<br />

America); nancito, crabo (Honduras); chaparru (Colombia); manteco,<br />

chaparro manteco (Venezuela); savanna serrette (Tr,.. lpd); huria (Guyana);<br />

sabana kwari moeleidan, hori (Suriname).<br />

Malpighla Family, Malpighiaceae<br />

Nance iscommonly a small crooked tree or shrub distributed extensively in<br />

dry forests and savannas throughout tropical America. This variable species is<br />

readily available for fuelwood. If planted for that purpose, perhaps superior<br />

varieties could be selected for wood production, as well as for fruits. It is easily<br />

recognized by its paired elliptical leaves, rusty-red hairs on young twigs,<br />

flower buds, and young leaves, its many flowers with 5 rounded, stalked,<br />

yellow petals, and its small, nearly round, yellowish fruits. This species, a<br />

fuelwood for arid and semiarid regions, is often planted for the fruits and for<br />

ornamental purposes.<br />

Byrsoninia, coming from Greek words meaning "hide" and "name," refers to<br />

the use of the bark in tanning leather, while the species name means "thick<br />

leaf." "Nance" is of Nahuatl origin. The genus has about 100 species in tropical<br />

America as far north as southern Florida; this species isthe most widespread.<br />

Legume Family, Leguminosae (Faboideae or Papilionoideae)<br />

Pigeon pea is a cultivated tropical food crop producing 4 percent of the<br />

world's total grain legumes. This shrub has very branchy, woody stems that<br />

or<br />

can be harvested as firewood, a by-product. Many cultivated varieties<br />

cultivars are available for different environments. Plants mature and produce<br />

seeds in 100-300 days, depending upon the variety, location, and time of sowas<br />

an annual or biennial,<br />

ing. For seed production this species is cultivated<br />

because harvest declines after the first year. Grown as an annual, the wood is<br />

used for fuel. This genus has only 1or 2 species.<br />

This species is recognized by the compound leaves with 3 lance-shaped,<br />

velvety, hairy leaflets, clusters of pea-shaped yellow or orange flowers, and<br />

abundant, narrowly oblong, slightly flattened pods containing 3-7 rounded,<br />

a fuelwood for arid and semiarid<br />

beanlike edible seeds. Cajanus cajan is<br />

regions and the humid tropics.<br />

Description Deciduous shrub or woody herb 1-3.6 m high, upright, bushy<br />

and much-branched, finely hairy, grown as an annual or short-lived perennial<br />

crop. Stems very slender, stiff, grooved, gray, silky hairy. Available in many<br />

varieties, such as tall, open and upright, and dwarf, compact and bushy.<br />

Leaves alternate, pinnately compound with stalk 1-3 cm or more in length<br />

and 3 leaflets (middle leaflet long-stalked), lnce-shaped to narrowly elliptical,<br />

2.5-8 cm long, 1-3 cm wide, long- or short-pointed at tip, short-pointed at base,<br />

not toothed on edges, soft or velvety hairy on both surfaces, dark green above,<br />

underneath grayish with gland-dots.<br />

Flowers in stalked clusters (racemes) 6-10 cm long at leaf bases, pea-shaped,<br />

1.5-2 cm long, broad, showy. Calyx narrowly bell-shaped, 5-lobed, with 2 upper<br />

lobes <strong>part</strong>ly united, brown, hairy; corolla variable, yellow or orange and<br />

often purplish outside, with large, broad standard curved back, oblique wings,<br />

Other Uses Seeds nutritious, of high protein content; boiled, used in<br />

soups, made into a sauce. Young green seeds, germinating seeds, and green<br />

pods also eaten as fresh vegetables. Young leaves reportedly edible raw or<br />

cooked.<br />

Livestock browse pods and seeds and less eagerly the foliage. Shoots and<br />

even dried plants good fodder for cattle, horses, other animals. Plants<br />

cultivated for feeding silkworms and the lac insects from which shellac is ob.<br />

tained. Pods and leaves have served in home remedies.<br />

Species important in improving soil<br />

fertility, through nitrogen-fixing<br />

nodules on the deeply penetrating roots and also when grown for green<br />

manure and plowed under. These hardy shrubs adapted to lands unsuited for<br />

other crops. Rapidly produce dense ground cover and extensive lateral root<br />

system, protecting the soil from erosion. Also used for windbreaks and hedges.<br />

Natural Distribution As species not found truly wild, the native home or<br />

original range is uncertain, perhaps southeastern Asia, East Indies, or northeastern<br />

Africa. Common and scientific names, perhaps suggesting origin, from<br />

Malayan term "katjang."<br />

Very widely planted in most of the world's tropical and subtropical countries<br />

at latitudes between 300 north and 300 south, for edible seeds, green manure,<br />

cover cr, .p. Now thoroughly naturalized. Cultivated range extends to Bermuda,<br />

southern Florida, West Indies, East Indies, Hawaii, Australia.<br />

Altitudinal range is from sea level to 3000 m.<br />

Species known in ancient Egypt<br />

at least 4000 years ago; grown widely in<br />

Africa and Southeast Asia since prehistoric times. Reached the Americas and<br />

Pacific countries in the colonial period. India produces more than 90 percent<br />

of the world's harvest on about 2.3 million ha.<br />

Climate and Soils Tropical and frost-free. Optimum annual rainfall<br />

600-1000 mm. However, species grows in humid areas with 2500 mm and in<br />

semiarid areas with only 400 mm. Soils wide ranging; thrives in light, sandy<br />

soils but grows best in neutral, deep loams and cannot withstand water­<br />

logging.<br />

(Indonesia).<br />

Legume Family, Leguminosae (Mimosoideae)<br />

This Central American shrub or small tree has become a promising fastgrowing<br />

firewood for the humid tropics. It was discovered in 1846 in<br />

Suriname and named in 1848 but not collected again for many years. Then it<br />

was found in Central America and was given 2 other scientific names. It was<br />

introduced to Indonesia from Guatemala in 1936. Growth in plantations in Indonesia<br />

is very rapid and dense, and coppicing is excellent. Small-sized<br />

fuelwood can be cut annually from the first year through the next 15-20 years.<br />

This hardy species might become a weed.<br />

Calliandra calothyrsus has bipinnately compound, feathery leaves, showy<br />

flower clusters with numerous threadlike, purplish-red stamens, and clusters<br />

of several upright, narrow, flat pods that split open elastically from tip to base<br />

and curve back.<br />

The genus Calliandrahas about 00 species of shrubs and small trees in<br />

tropical and warm temperate regions. The generic name of Greek origin<br />

means "beautiful male elements" or stamens. The specific name, also Greek,<br />

refers to the beautiful branched flower cluster.<br />

Description Large shrub 1.5-3 m high or small tree 4-6 m (rarely 10 m),<br />

with trunk diameter of 3-20 cm, few branches or unbranched. Bark blackishbrown.<br />

Twigs angled, rusty, hairy when young, becoming nearly hairless.<br />

Leaves alternate, bipinnately compound, feathery, with glandless axis 10-17<br />

Cassia siarnea has long been planted for firewood crops but is now <strong>part</strong>ly<br />

replaced by faster-growing trees.<br />

Livestock and wildlife browse and damage young trees. The seeds, pods,<br />

Trees blown over or broken by storms increase the d-nger. Thus, hogs must<br />

be kept out of plantations. Cattle and sheep apparently are not affected.<br />

Cassia is from the Greek name. Specific and common names refer to Siam,<br />

now Thailand. This genus in the broad sense has 500-600 species of trees,<br />

shrubs, and herbs in tropical and warm temptrate regions. Cassiasiarnea is a<br />

Wood with thick, light brown or whitish sapwood and heartwood dark<br />

brown or blackish with dark and light streaks, hard, heavy (sp. gr. 0.6-0.8).<br />

Susceptible to attack by dry-wood termites but perhaps resistant in some<br />

localities, according to reports.<br />

Makes excellent, but "smoky" fuel. Formerly preferred for locomotives because<br />

of high calorific value.<br />

Other Uses Used for posts, construction, mine props, furniture, turnery.<br />

Attractive wood suitable also for cabinetry and inlays. Apparently not suited<br />

for pulpwood, according to tests. Tannin has been extracted from bark.<br />

Serves to reforest denuded hills, cutover areas, abandoned mining sites.<br />

Used in India as host for sandalwood (Santalum album), t parasitic tree. Trees<br />

(Australia).<br />

Casuarina Family, Casuarinaceae<br />

CASUARINA<br />

casuarina, beefwood, Australian-pine (English); she-oak<br />

trees and shrubs<br />

The genus Casuarina has about 45 species of evergreen<br />

native mostly to Australia and southeastern Asia and Polynesia. Most species<br />

produce top-quality firewooLd that ranks among the best fuels of Australia. The<br />

trees are fast-growing, hardy, salt-tolerant, and wind.resistant. They are! able<br />

to grow in poor sites, such as sand dunes and eroded soils, where other plants<br />

cannot. Like legumes, this genus has root nodules containing nitrogen-fixing<br />

microorganisms which enrich the soil. Within this genus are species adapted<br />

to various climates and soils.<br />

With another smaller closely related genus, Casuarinaforms a very distinct<br />

plant family easily recognized by the wiry, cylindrical, grooved and jointed<br />

reduced to rings of<br />

twigs and the drooping or weeping habit. The leaves are<br />

tiny gray or brown scales at joints or nodes. The very slender green twigs serve<br />

of leaves, and shed gradually. The tiny,<br />

for food manufacture instead<br />

crowded, brownish flowers are male and female in separate clusters on the<br />

same or different trees. Male flower clusters (like spikes or catkins) are narrow,<br />

cylindrical, mostly at ends of twigs; each male flower has I stamen and 2<br />

tiny brown sepals and 2 scales at the base. Female flower clusters (heads) are<br />

balls at sides of twigs; each female flower above 2 scales is a pistil composed of<br />

a small ovary with 2 ovules and a short style with 2 long stigmas. The multiple<br />

light brown, hard, warty, conelike ball, containing many tiny<br />

fruit is a<br />

1-seeded winged nutlets.<br />

Casuarina is from the Malay word "kasuari," or cassowary, which indicates<br />

the supposed resemblance of the twigs to the plumage of that bird. The common<br />

name "she-oak," widely used in Australia, refers to the wood's attractive<br />

pattern of large lines or rays like oak but weaker. The term "beefwood" refers<br />

to the reddish color. "Australian-pine" refers to the similarity of the wiry green<br />

twigs and conelike fruits to the needlelike leaves and cones of the unrelated<br />

true pines. The name "ironwood" used in Hawaii to describe the hard wood,<br />

should be avoided because of the confusior)caused by its application to many<br />

different trees.<br />

Firewood Crops describes in detail Casuarina equisetifolia, the most widely<br />

planted species of the genus, and lists 14 others. This species and 2 others are<br />

This species is recognized by the very thin, short twigs and small, round,<br />

conelike fruits 10-12 mm<br />

in diameter. This is one of the most cold-hardy<br />

species of Casuarinaand is often planted in mountainous areas. It is fastgrowing<br />

and can withstand some drought. Seedlings must be protected from<br />

browsing by livestock. It is not recommended for cities, because of the large<br />

root systems and space needed. The name of this species honors Alan Cunn-<br />

ingham (1791-1839),<br />

Australian botanist and explorer and superintendent of<br />

the Botanic Gardens at Sydney. This is a fuelwood species for humid tropics<br />

and tropical highlands.<br />

28. Colophospermum mopane<br />

Botanical Name Colophospermum mopane (Kirk ex Benth,) Kirk ex J.<br />

LUonard<br />

Synonym Copaifera mopane Kirk ex Benth.<br />

Common Names mopane, mopanie, mupani, mupane; butterfly-tree,<br />

turpentine-tree, Rhodesian ironwood, balsam-tree (English); sanya<br />

(Nyasaland); mopani (India).<br />

Legume Family, Leguminosae (Caesalpinoideae}<br />

Mopane is easily recognized by the distinctive leaves with 2 leaflets resembling<br />

butterfly wings that fold together at midday and in hot weather, by<br />

the kidney-shaped 1-seeded pods with tiny giaaid-,iots, and the strong odor of<br />

turpentine. This tree has very hard, heavy wooO claimed to be "the best<br />

firewood in Africa." It is a fuelwood species for arid and semiarid regions but<br />

apparently has not been tested in plantations for comparison with exotic trees.<br />

Mopane is one of the principal trees of hot lowlands in southern tropical and<br />

subtropical Africa. It is dominant in a distinct vegetation type in the deciduous<br />

or savanna forest. Often it forms pure stands of 'large monotonous shadeless<br />

forests" called mopane woodland or bush. Where stunted, mopane scrub indicates<br />

poor soils unsuited to agriculture. The trees are subject to forest fires<br />

throughout the year and may be destroyed by veld-fires when small.<br />

The small lightweight pods are dispersed by wind and by adhering to the<br />

feet of animals. Seeds germinate readily, but seedlings are slow-growing and<br />

sensitive, to frost. This species coppices vigorously. A cleared area grew back<br />

to forest within 15 years, according to reports.<br />

For firewood plantations, other species may grow faster. However, under<br />

extremely unfavorable conditions, mopanc may be the hardiest.<br />

This species has been 3egregated fron, ,he larger genus Copaifera into its<br />

own genus. The generic name is from Greek words meaning "oily seed."<br />

"Mopane" is the native name as spelled by its author, John Kirk (1832-1922), a<br />

British physician and naturalist with the Livingstone Expedition. He collected<br />

a specimen in Mozambique in the 1860's and later made extensive collections<br />

of economic plants during many years in Africa.<br />

Description Small or medium-sized deciduous spineless tree 4-18 m<br />

(sometimes 23 m, commonly about 10 mi, with 1or more straight trunks 50<br />

cm-I m in diameter and open, very thin, V-shaped or spreading crown of few<br />

nearly upright branches. Shrublikc and very branchy in very dry areas. Bark<br />

distinctive, gray to blackish, thick, very rough, deeply furrowed into long, narrow,<br />

forking, flaking ridges. Twigs slender, hairless, pale brown, becoming<br />

light to dark gray.<br />

Leaves distinctive, alternate, compound, axis 2-4 cm long, ending in small<br />

point of 3 mm. Leaflets 2, paired, stalkless, resembling butterfly wings, ovate<br />

long,<br />

2-2.5 cm wide, pale yellow or light brown with network, slightly<br />

leathery and thick-walled, not opening. Seed 1, kidney-shaped or oblong, very<br />

wrinkled, yellowish, covered with small, red, resinous or sticky gland-dots,<br />

oily with strong odor of turpentine.<br />

Wood dark brown to reddish-brown with darker streaks or blackish, with<br />

sharply defined straw-colored or yellowish sapwood, very hard, very heavy<br />

(sp. gr. 0.89), texture moderately coarse but even, grain interlocked, growth<br />

rings usually distinct. Durable and resistant to termites but difficult to work.<br />

Excellent firewood burning slowly and<br />

quietly with fragrance and pro-<br />

ducing intense heat. Log left on the fire in the evening may still be burning the<br />

next morning. After bush fires, fallen mopane trees often smolder for weeks.<br />

Burns green and produces good charcoal. Residue of fine white ash, though<br />

negligible, used locally as fertilizer; high in phosphate and calcium.<br />

Botanical Name Dalbergiasissoo Roxb. ex DC.<br />

Common Names sissoo, Indian rosewood, Bombay blackwood, shisham,<br />

nelkar, safeda; sissoo, tali, yette (India); sarsou (Egypt); sonossissoo (Java);<br />

sisu (Spanish).<br />

Legume Family, Leguminosae (Faboideae or Papilionoideael<br />

Sisso, or Indian rosewood, is a valued timber tree from India. Its wood is in<br />

great demand for general construction and is excellent for fuel and charcoal. It<br />

is widely planted in tropical countries, especially arid and semiarid regions,<br />

for both wood and shade.<br />

The trees are fast-gfowing, salt-tolerant, drought-resistant, frost-hardy, and<br />

intolerant of shade. They are propagated by seeds, transplants, and root<br />

suckers. Spreading from root suckers and runners, the trees are used for ero­<br />

sion control in gullies.<br />

This genus with about 300 species of tropical and subtropical woody plants<br />

was named for Nils Dalberg (1735-1820), Swedish botanist. Sissoo is characterized<br />

by pinnate leaves with 3-5 rounded, abruptly short-pointed leaflets, many<br />

small whitish or yellow pea-shaped flowers, and oblong, flat, thin pods.<br />

Description Medium to large tree to 30 m high, with trunk to 80 cm in<br />

diameter, often crooked, with rounded open crown of spreading branches,<br />

deciduous or almost evergreen. Bark gray, scaly, deeply furrowed, shedding<br />

in long narrow strips. Twigs green to gray, very slender.<br />

Leaves alternate, pinnately compound, about 15 cm long, hairy when<br />

young. Leaflets 3-5, alternate on leafstalks of 6 mm, along very slender zigzag<br />

axis and almost at right angle, nearly round, 2.5-5 cm long and broad,<br />

rounded, abruptly short-pointed ai tip, rounded or blunt at base, not toothed<br />

on edges, thin, with many fine parallel side veins, paler green underneath.<br />

Flower clusters (panicles) 5-10 cm long at leaf bases and nodes back of<br />

leaves, branching, hairy. Flowers many, small (about 1 cm long), whitish or<br />

yellow, pea-shaped, fragrant. Calyx 5-toothed; corolla with 5 petals, broad<br />

, 9 united into broad stalk; and<br />

standard, 2 narrow wings, narrow keel; stamen<br />

stalked, hairy pistil with narrow 1-celled ovary containing few ovules, short<br />

style, and dot stigma.<br />

Pods (legumes) oblong, flat, thin, 3-7.5 cm long, 10-12 mm wide, light<br />

brown, narrowed at both ends, stalked at base, not splitting open. Seeds 1-5,<br />

bean-shaped, 6-10 mm long.<br />

Wood with sapwood white to pale brownish-white and heartwood golden<br />

brown to dark brown with deep brown streaks, moderately heavy to heavy<br />

(sp. gr. 0.80), very hard and strong, medium-coarse-textured, with interlocked<br />

grain, diffuse-porous with inconspicuous growth rings. Heartwood extremely<br />

durable, one of the Indian woods least susceptible to dry-wood termites.<br />

Botanical Name Derris indica (Lam.) Bennet<br />

Synonyms Pongamiapinnata (L.) Pierre, Pongamia glabraVent.<br />

Common Names pongam, pongamia, poonga-oil-tree, karum-tree, dona,<br />

kanji, pari-pari, karanda, karanja, Indian-beech; kuro-yona zoku (Okinawa);<br />

bfni (Philippines); melapari (Indonesia); langi poka (Celebes).<br />

Legume Family, Leguminosae (Faboideae or Papilionoideae ,<br />

Pongam or ponganiiiis native of the Indian subcontinent but is widely<br />

introduced in humid tropical regions. The wood is a popular firewood, and the<br />

oil from the large seeds is burned in lamps. Pongam is identified by the pinnately<br />

compound leaves having 5 or 7 elliptical leaflets, the abundant, peashaped,<br />

pink, purplish, or white flowers, and the quantities of elliptical, slightly<br />

swollen pods with I large oily seed.<br />

Pongam is easily grown from seed and cuttings and is drought-resistant.<br />

However, it spreads from root suckers as well as seedlings and could become<br />

an undesirable weed.<br />

This species usually has been placed alone in its genus Pongamia, derived<br />

from the common name. However, within recent years it has been united<br />

with the larger genus Derris,with about 80 tropical woody species. That name,<br />

derived from Greek, means "leather covering or skin." The specific name obviously<br />

means "of India."<br />

Description Medium-sized deciduous or evergreen tree 8 m high (sometimes<br />

to 15 m), with straight or crooked trunk 50-70 cm or more in diameter<br />

and broad crown of spreading or drooping branches. Bark gray-brown,<br />

smoothish to rough. Twigs hairless.<br />

Leaves alternate, pinnately compound with long slender leafstalk, hairless.<br />

Leaflets 5 or 7, paired except at end, short-stalked, elliptical, 5-10 cm long, 4-6<br />

cm wide, abruptly long-pointed at tip, short-pointed at base, not toothed on<br />

edges, slightly thickened, shiny light green deepening to dark green, crimson<br />

when young.<br />

Flowerclusters (racemes) at base of and shorter than leaves, to 15 cm long,<br />

slender, drooping. Flowers abundant after leaves formed, fragrant, 2-4<br />

mclakka (Peninsular Malaysia); aonla, mirobalano.<br />

Spurge Family, Euphorbiaceac<br />

Emblic is a wild and cultivated fruit tree of southern Asia, with rounded,<br />

greenish-yellow or sometimes reddish fruits, which are very sour and rich in<br />

vitamin C. As a fruit tree, this species is propagated vegetatively by budding,<br />

cuttings, and inarchin3. Fruits from seedlings may be small and inferior. The<br />

wood is good fuel and makes excellent charcoal, for arid and semiarid regions.<br />

Emblic is recognized by the small, crowded, oblong leaves in 2 rows resembling<br />

a pinnately compound leaf.<br />

Emblica is from the Bengalese plant name "amlaki." Officinalis, from a Latin<br />

word meaning "officinal" or "sold in a shop," refers to the medicinal use.<br />

"Malacca," a word of Sanskrit origin for town and river, is believed to have<br />

been derived also from the name of this tree. This genus of 4 species from<br />

Madagascar to eastern Asia is also united under Phyllanthus.<br />

Description Small to medium-sized tree, deciduous or nearly evergreen,<br />

becoming 18 m high (rarely 30 m), with trunk to 60 cm in diameter, often<br />

fluted and twisted, and with graceful irregular crown of feathery, pale green<br />

foliage. Bqirk pale gray-brown, thin, peeling in oblong, papery scales exposing<br />

smooth, orange-brown layers; inner bark pinkish-brown, green beneath surface,<br />

softly fibrous, very astringent. Twigs reddish-brown, finely hairy,<br />

slender.<br />

Leaves alternate in 2 rows on slender deciduous twigs 7-15 cm long,<br />

resembling a pinnately compound leaf, crowded, very short-stalked, oblong,<br />

7-25 mm long, 2-4 mm wide, short-pointed at tip, rounded at base, edges<br />

slightly curved, leather,, bright green upper surface, whitish underneath,<br />

pinkish when young.<br />

EUCALYPTUS<br />

Common Names eucalyptus, eucalypt (English); eucalipto, eucaliptus<br />

(Spanish); mkaratusi (Tanzania); nilgiri, safeda (India); hue (Indonesia).<br />

Myrtle Family, Myrtaceae<br />

The genus Eucalyptus (from the Greek meaning "well covered," referring to<br />

the flower) is important for firewood crops because the trees grow rapidly and<br />

attain great size, and because it contains numerous species adapted to many<br />

climates. The natural habitat of this large genus of about 500 species, among<br />

them the world's tallest hardwoods, is almost confined to subtropical and<br />

tropical portions of Australia. A few species are native on islands nol ihward to<br />

the Philippines as shown in Figure 55. Many species are now widely planted<br />

around the world for their wood, shade, ornament, and other values.<br />

Ageneric description is given below for identification and recognition. Next<br />

follow general references for identification and a key to the 10 species described<br />

and illustrated here. Firewood Crops treated the first 7 in detail and<br />

briefly mentioned the last 3.<br />

Trees of this genus are<br />

large to very tall aromatic evergreen trees (a few<br />

species are shrubs); most have resin or gum. Several groups are distinguished<br />

by the bark: "gums"with smooth bark; "bloodwoods" with scaly bark; "stringybarks"<br />

with thick, fibrous bark; and "iron-barks"with hard, furrowed, blackish<br />

bark.<br />

Leaves are mostly alternate, lance-shaped, long-pointed, not toothed on<br />

edges, slightly thickened, shiny green, hairless, and drooping along slender<br />

twigs. Young plants have juvenile leaves of different shape; they are mostly<br />

opposite for 3-5 pairs, broad, often ovate, with short leafstalks or none.<br />

Single (often several) flower clusters (commonly umbels) are found at the<br />

leaf bases. There are usually several flowers on short equal stalks spreading at<br />

the end of a longer stalk. The distinctive flower bud is composed of a cupshaped<br />

base (hypanthium) and a mainly conical and pointed lid (operculum),<br />

which corresponds to a calyx or corolla and sheds early. There are many<br />

threadlike, mostly white stamens with small anthers useful in classification.<br />

The pistil has an inferior ovary within its base; it generally is 3-5-celled, contains<br />

many tiny ovules, and has a stout style. The fruit is a hard seed capsule<br />

(mainly 3-5-celled) that opens at the top and generally has as many protruding<br />

teeth or lines as cells. There are many small seeds; some are tiny and nonfunctional.<br />

32. Eucalyptus camaldulensis<br />

Botanical Name Eucalyptus carnaldulensis Dehnh.<br />

Synonym Eucalyptus rostrata Schlecht.<br />

Common Names river redgum eucalyptus, longbeak eucalyptus; river<br />

redgum, redgum, Murray redgum, river-gum (Australia); eucalipto rojo<br />

(Ecuador); ilachi, gond (Pakistan).<br />

Myrtle Family, Myrtaceac<br />

This example of the redgum group is the species of Eucalyptus having the<br />

broadest range in Australia as well as being one of the most widely planted<br />

over the world. It is recognized by the small flowers clustered at leaf bases, the<br />

bud ending in a long narrow point, the small half-round seed capsules opening<br />

by 3-4 teeth, and the smoothish white bark. The wood is an outstanding fuel as<br />

well as an important hardwood.<br />

Minor botanical varieties differing mainly in shape of fruit and its lid have<br />

been named. There are different races or provenances adapted to special<br />

climates, such as tropical, Mediterranean, arid, or high altitude. For successful<br />

reforestation it is essential to select seed from a climatic zone similar to that of<br />

the planting area, for example, in latitude, altitude, temperature, and rainfall,<br />

and also soil type and pest resistance.<br />

The specific name, referring to Hortus Camaldulensis, a garden near Naples,<br />

Italy, is based upon a tree cultivated there in 1832. The term "gum"is applied<br />

to species with smooth bark; red describes the color of the wood. This is a<br />

fuelwood species for arid and semiarid regions and also for the humid tropics<br />

and tropical highlands.<br />

Description Large evergreen tree 24-40 m high (to 50 m in Australia), with<br />

stoitt trunk often short and crooked, becoming 60 cm to I m (sometimes 2 m)<br />

in diameter; and open, widely spreading irregular crown. Bark mostly<br />

smoothish, white, light gray, or buff, often with patches of darker gray and<br />

red, peeling in long strips or irregular flakes and exposing whitish inner layers,<br />

flaky bark persisting toward base. Twigs reddish, long, very slender, angled,<br />

drooping. Trunk can form air roots. Root system deep and spreading.<br />

Leaves alternate, drooping on slender leafstalks of 12-25 mm, narrowly<br />

lance-shaped to lance-shaped, 8-22 cm long, 1-2 cm wide, often curved or<br />

sickle-shaped, tapering to long point, short-pointed at base, not toothed on<br />

edges, hairless, thin or slightly thickened, with many fine straight side veins at<br />

an angle and vein inside edge, dull pale green on both surfaces or occasionally<br />

grayish. Juvenile leaves opposite or 3-4 pairs, then alternate, stalked, ovate to<br />

broadly lance-shaped, 6-9 cm lcng, 2.5-4 cm wide, gray-green.<br />

Flower clusters (umbels) single at leaf base, about 2.5 cm long on slender<br />

stalk of 6-19 am. Flowers 5-10, each on slender stalk of 5-12 mm, from eggshaped<br />

bud 6-10 mm long and 4-5 mm wide, with half-round base (hypanthium)<br />

and longer conical lid with long, narrow point or beak. Stamens, many,<br />

to termites, not difficult to saw, takes a fine finish, but tends to warp in<br />

drying.<br />

As firewood, Eucalyptus camaldulensis has few equals. An outstanding fuel<br />

when fully dry; highly valued ii, Australia. Makes very good charcoal. Argentine<br />

steel industry relies on this charcoal for steelmaking. One limitation is<br />

that wood burns quickly and smokes heavily.<br />

Other Uses In Australia ihis important inland hardwood used extensively<br />

for structural timbers where strength and durability required, railroad crossties,<br />

and geaeral construction. Also used for interior finish, flooring, furniture,<br />

cabinetwork, fenceposts, and sometimes pulpwood.<br />

Trees planted for shade and ornament, along roadsides, and in shelterbelts,<br />

windbreaks, farm woodlots. Classed as good honey plant in Australia, flowering<br />

nearly all year and producing clear or pale honey with mild, pleasant<br />

flavor. Australian aborigines made canoes from bark and obtained drinking<br />

water from roots, as noted under Eucalyptus microtheca.<br />

tending over 230 of latitude. Found in most <strong>part</strong>s of Australia including arid<br />

and semiarid areas but not the humid eastern and southwestern coasts,<br />

western interior, nor Tasmanin. Mostly in lowlands at 30-230 m altitude but<br />

extends up higher slopes to 600 in.<br />

This species and Eucalyptus globulus are the most widely planted eucalypts in<br />

the world, this <strong>part</strong>icularly in arid regions. One of the first ecualypts to be introduced<br />

overseas, planted in Naples in 1803 and now the dominant eucalypt<br />

around the Mediterranean. In Hawaii, where introduced in the 1880s, one of<br />

the most con ionly planted eucalypts, primarily in windbreaks. One of the<br />

best eucalypts for inland valley planting in California; more tolerant of<br />

drought, frost, and alkali than Eucalyptus globulus, but slower-growing.<br />

Climate and Soils Within the extensive natural range varies from tropical<br />

to subtropical and warm temperate, and from arid to semiarid. Temperatures<br />

high, especially in summer; as low as 30 to - 5°C in winter with 0-50 frosts according<br />

to locality. Annual rainfall where native varies considerably from<br />

minimum of about 250-625 mm to as high as 1000-1250 mm on limited areas.<br />

Tropical zone of northern Australia has summer rainfall; temperate zone of<br />

the southern region has winter rainfall. Dry seasons may be prolonged. Soils<br />

vary greatly from poor to periodically waterlogged. In Australia species forms<br />

pure forests on flood plains, stream banks, and similar moist habitats. May be<br />

found with other eucalypts on adjacent higher ground. Frequently occurs in<br />

the savanna woodland.<br />

Climate and Soils In the native home humid and subtropical without extremes<br />

of heat or cold and 0-5 frosts. Annual rainfall 500-1500 mm, mainly in<br />

winter but well distributed with a dry season up to 3 months. Soils include<br />

well-drained sandy clays and loams. In cooler <strong>part</strong>s of its range, species grows<br />

on undulating country near the sea, but in warmer <strong>part</strong>s is in valleys of the<br />

hilly country.<br />

Species adapted to subtropical climates with winter rainfall, such as the<br />

Mediterranean region, and to cool zones of tropical mountains but not hardy<br />

in warm temperate climates.<br />

Subspecies Three closely related species of coastal southeastern Australia<br />

but not Tasmania have also been united as subspecies (Kirkpatrick 1974), as<br />

follows:<br />

Common Name tuart<br />

Myrtle Family, Myrtaceae<br />

Tuart is one of the heaviest and most durable timbers in Australia and one of<br />

the most valuable in the western <strong>part</strong> of that continent. However, its supply is<br />

limited in southwestern Australia. It is distinguished by the flower bud that<br />

resembles a mushroom with a half-round lid broader than its base.<br />

good firewood, grows naturally in pure or<br />

suitable for dry areas and has poor frost tolerance. Tuart is easily propagated<br />

from seed and coppices well. This is a fuelwood species for arid and semiarid<br />

regions and also for tropical highlands.<br />

The specific name from Greek words meaning "bolt" and "head" refers to the<br />

a very broad, half-round lid. "Tuart," the common<br />

distinctive flower with<br />

name, is of aboriginal origin.<br />

37. Eucalyptus microtheca<br />

Botanical Name Eucalyptus microtheca F. Muell.<br />

Common Names coolibah, coolabah, flooded-box, western coolibah (Aus.<br />

tralia).<br />

Myrtle Family, Myrtaceae<br />

Coolibah is easily recognized by the clusters of numerous, very small<br />

flowers at the ends of twigs and the tiny seed capsules opening with 3-4 teeth.<br />

This is one of the most widely distributed species of Eucalyptus, ranging across<br />

arid northern and central <strong>part</strong>s of Australia.<br />

This tree is commonly found in open savannas or woodlands subject to seasonal<br />

flooding, including edges of swamps or lagoons and the extensive<br />

floodplains of inland rivers. The wood, classed among the world's hardest,<br />

makes good fuel but has few other uses because of its poor form, hardness,<br />

and weight.<br />

Coolibah is variable in character of bark, wood, and fruits, and a related<br />

species has been united as a synonym. One variation known as "blackheart"<br />

has smooth whitish bark. The specific name, Greek for "small case," describes<br />

the very small seed capsules, among the smallest in the genus. "Coolibah" is<br />

the aboriginal name. This is a fuelwood species for arid and semiarid regions<br />

and also for the humid tropics.<br />

Description Small to medium-sized evergreen tree 6-12 m high, with<br />

usually crooked or irregular short stout trunk 30-60 cm in diameter (sometimes<br />

to 20 m high and I m in diameter), often several trunks, with low<br />

branches and wide spreading crown; or a stunted shrub of 3 m. Bark gray or<br />

blackish, thick, fibrous, rough, more or less scaly to deeply furrowed toward<br />

base, not shedding; bark of upper branches usually with smooth whitish or<br />

light gray bark shedding in strips, rarely extending nearly to base. Twigs<br />

slender, angled, often whitish.<br />

Leaves alternate, drooping on slender leafstalk of 1-2 cm,variable in shape,<br />

narrowly lance-shaped, 6-20 cmIlop, 1-3 cm wide, long-pointed at tip, shortpointed<br />

at base, not toothed on edges, hairless, slightly thick, leathery, dull<br />

green, slightly paler underneath, with inconspicuous veins forming fine network<br />

and vein near edge. Juvenile leaves opposite for 4-5 pairs, short-stalked,<br />

variable, lance-shaped, 4-7 cm long, 2-3 cm wide, dull whitish-green.<br />

Flower clusters (panicles) mostly at and near ends of twigs, short, branched<br />

with slightly angled slender stalks ending in clusters (umbels) of 3-7 shortstalked<br />

fragrant flowers. Flowers very small from egg-shaped, short-pointed<br />

bud 4-6 mm long, with half-round or conical lid shorter than top-shaped or<br />

conical angled base (hypanthium). Stamens many, spreading, white, short, 3-4<br />

Trees planted for shelterbelts, shade, soil conservation, and erosion control<br />

Natural Distribution Widespread though scattered throughout interior<br />

of Australia except southern <strong>part</strong>; in all states except Victoria and the island of<br />

Tasmania. Altitude mainly from 80 to 340 ,n, and up to 700 ni. Introduced successfully<br />

on a small scale in arid <strong>part</strong>s of northern Africa and southwestern<br />

Asia.<br />

Climate and Soils Semiarid or arid tropical or desert with hot<br />

temperatures most of the year. Can withstand afew frosts a year. Annual rainfall<br />

in most of native range 250-1000 mm and as low as 200 mm with a dry<br />

season of up to 7 months. At southeastern edge of the range, annual summer<br />

rainfall 500 mm. In the northern <strong>part</strong>, rainfall seasonal or monsoonal and up to<br />

1000 mm annually. Soils mostly clays or silty clay loams of seasonally flooded<br />

watercourses, often alkaline.<br />

This species is one of the eucalypts with water-yielding roots and known<br />

also as weir-mallees. An account by Mueller (1884) on the method of obtaining<br />

drinking water is quoted below. Maiden (1913, vol. 2, pp. 14-15; vol. 6, pp.<br />

21-22) recorded additional details for this species and Eucalyptus camnaldulensis.<br />

The lateral roots are lifted by the natives with sharp-pointed sticks or their<br />

spears to the surface from about a foot or less depth and to a distance of 15 or<br />

more feet from the tree: the overlying earth when necessary being removed by<br />

wooden shovels: the root is then cut into pieces of about 18 inches length and the<br />

bark peeled off: if the water, on placing these fragments vertically, does not at<br />

once commence to come out spontaneously, the process is expedited by blowing<br />

vigorously at one of the ends of the root-pieces; roots of the size of a man's wrist<br />

are the best for this operation, Mr. Bennett obtained in -ost favorable cases by<br />

these means a quart-pot full of water in half an hour and found it beautifully<br />

clear, cool and free from any unpleasant taste. (Roots from depressions in the<br />

ground yielded water more copiously, and main roots near the trunk were not<br />

sufficiently porous for obtaining water.)<br />

Messrs. Muir saw Desert-Eucalypts also used widely in South-Western<br />

Australia for obtaining drinking water from the roots, the Aborigines having entirely<br />

to depend on this source of water in many of their hunting excursions, the<br />

roots chosen being about one inch in thickness, the surrounding soil being often<br />

dusty dry.<br />

Botanical Name Eucalyptus occidentalis Endl.<br />

Common Names flat-topped yate, swamp yate (Australia).<br />

Myrtle Family, Myrtaceae<br />

This slow-growing, hardy tree, which is drought-tolerant, can grow where<br />

other eucalypts do poorly. Its wood is very hard and heavy. Eucalyptus occidentalis<br />

is characterized by clusters of 3-7 flowers at the end of a broad flat stalk,<br />

long narrow buds, long yellowish-white stamens, bell.shaped seed capsules<br />

with 4 raised teeth, and dark gray, rough bark. This is a fuelwood species for<br />

arid and semiarid regions.<br />

Description Medium-sized evergreen tree 15-21 m high (sometimes to 28<br />

ml, with stout erect trunk to 80 cm in diameter and upright branches of about<br />

equal length forming broad flat-topped or umbrellalike crown; sometimes a<br />

small tree of 6 m. Bark dark gray or almost black, thick, rough, fissured,<br />

fibrous, hard, not shedding; bark of branches light gray or yellowish-gray,<br />

smooth, flaky with loose ribbons. Twigs slightly angled, reddish-brown.<br />

Leaves alternate, with short leafstalk to 2 cm long, narrowly to broadly<br />

lance-shaped, 10-14 cm long, 2-3 cm wide, short-pointed at both ends, sides<br />

nearly equal, not toothed on edges, hairless, thick, with side veins spreading<br />

and slightly prominent and with vein near margin, shiny dark green on both<br />

surfaces. Juvenile leaves opposite for 4-5 pairs, short-stalked, lance-shaped to<br />

ovate, 7-12 cm long, 3-7 cm wide, thin, slightly whitish.<br />

Flower clusters (umbels) single at leaf base, with broad flat stalk 15-25 mm<br />

long. Flowers 3-7, short-stalked, from cylindrical conical bud to 20 mm long,<br />

with narrow blunt-pointed lid twice as long as bell-shaped base (hypanthium).<br />

Stamens many, long, 8-20 mm long, straight in bud, yellowish-white, threadlike,<br />

slightly 4-angled, with tiny gland-dots, oblong anthers with oblong gland.<br />

Pistil with inferior conical 4-celled ovary and long slender style.<br />

Fruitsor seed capsules short-stalked, bell-shaped, 10-18 mm long, 8-12 mm<br />

wide, brown, finely streaked, with narrow rim, 4-celled, opening with usually<br />

4 raised short-pointed teeth. Seeds few, tiny, 2 mm long, brown, with many,<br />

very small sterile seeds.<br />

Wood yellow-brown with pale yellow sapwood, very hard, very heavy, fairly<br />

straight-grained, strong, durable. Reportedly one of the hardest and<br />

strongest timbers in the world, having a tensile strength slightly below that of<br />

wrought iron. Wood burns steadily with a hot fire.<br />

Other Uses Used for wheelwright work, especially <strong>part</strong>s requiring great<br />

strength and toughness, such as vehicles, frames, and wheel <strong>part</strong>s; also construction.<br />

Bark, with high tannin c6ntent, formerly was harvested.<br />

Species recommended as a shade tree in Western Australia. Suitable for<br />

parks because light shade permits growth of grass. A good honey plant.<br />

with some interlocked grain. Difficult to season and split but works<br />

well and takes a good polish. Very susceptible to attack by dry-wood termites<br />

but considered durable in the ground.<br />

Other Uses<br />

Although of limited supply in Australia, wood employed for<br />

general construction, especially for <strong>part</strong>s in contact with the ground. Also used<br />

for underground piling, utility poles, fenceposts, in addition to fuel. Is an attractive<br />

shade tree and ornamental; used also for windbreaks. A good honey<br />

plant.<br />

This important general purpose hardwood and construction timber in<br />

Australia is classed in the eastern bluegum group. It is commonly mixed with<br />

other eucalypts, occasionally in pure stands, in valleys, slopes, and ridges.<br />

In Hawaii it is tile fastest-growing eucalypt. A tree 71 m high is the tallest<br />

tree in Hawaii and the tallest hardwood in the United States. This species is<br />

identified by the smooth bluish bark, dull green lance-shaped leaves with<br />

many scarcely visible, parallel side veins and bell-shaped seed capsules with<br />

3-5 slightly projecting teeth. This fuelwood species for tropical highlands and<br />

the humid tropics is mentioned in Firewood Crops under Eucalyptus grandis.<br />

The two closely related species have been confused and will hybridize.<br />

Eucalyptus saligna grows naturally on slopes and is suitable for moist cool<br />

mountains. The closely related species Eucalyptus grandis is found on bottomlands<br />

and is suitable for moist warm lowlands.<br />

eucalyptus; forest redgum, Queensland bluegum (Australia); Mysoregum<br />

(India).<br />

Myrtle Family, Myrtaceae<br />

Eucalyptus tercticornis, one oi the eucalypts of greatest latitudinal range, is<br />

classed in the redgum group. It is recognized by the long hornlike lid of the<br />

flnwer buds, the shiny green narrowly lance.shaped leaves, and the smooth<br />

whitish bark. Where native this species usually is in open forests or scattered<br />

on alluvial flats and stream banks. In cooler and drier areas, it is common on<br />

alluvial flats with some flooding. In areas of high rainfall, it grows on lower<br />

slopes of hillsides and in the tropics up to mountain slopes and plateaus.<br />

Promising hybrids have been developed. The specific name from Latin<br />

meaning "long," "round" and "horn," refers to the very long hornlike lid (operculuml<br />

of the bud. This is a fuelwood species for arid and semiarid regions and<br />

the humid tropics and tropical highlands.<br />

Australia), with straight stout trunk 1-1.8 m in di&.neter, large and open or<br />

fairly dense crown, variable. Bark smooth, whitish, peeling i%irregu',ar th'n<br />

sheets or large flakes, becoming mottled with white, gray, or bluish patches,<br />

often with some rough, dark gray bark at base. Twigs reddish or yellowishgreen.<br />

Leaves alternate, drooping on slender leafstalk, narrowly lance-shaped,<br />

10-21 cm long, 12.25 mm wide, often curved, long-pointed at tip and shortpointed<br />

at base, slightly thickened, shiny green on both surfaces, hairless,<br />

with many fine side veins at an angle and distinct vein along edge. Juvenile<br />

leaves opposite for 2.3 pairs, with slender leafstalks, elliptical to broadly lanceshaped,<br />

included under tropical<br />

Honeylocust of the eastern United States is<br />

highlands and arid and semiarid regions in the Master List of Firewood Species<br />

in FirewoodCrops and is added here. This hardy temperate zone tree has been<br />

introduced into many countries and produces good firewood. Honeylocust<br />

generally is scattered in deciduous forests with oaks (Quercusspp.) and other<br />

hardwoods and is not a major component of forest stands. This intolerant tree<br />

becomes established in openings. It is a pioneer in rocky limestone glades and<br />

in strip-mine spoil-banks.<br />

Propagation is mainly by seeds but can be vegetative from hardwood, greenwood,<br />

and root cuttings. Plants sprout from roots and produce many suckers.<br />

Growth is fairly rapid to miturity in about 120 years. The roots do not produce<br />

nodules, as do most tree legumes. Varieties with abundant large pods high in<br />

sugar content have been selected and can be propagated vegetatively.<br />

This species is readily identified by the very large branched spines on the<br />

Legume Family, Leguminosae (Faboideac or Papilionoideae)<br />

Best known as a living fence, this tropical American small tree is also a<br />

fuelwood species for the humid tropics. It is common in many <strong>part</strong>s of Central<br />

America in plains, foothills, and lower mountain slopes in seasonal forests<br />

with a dry season. The trees are easily prupagated by seeds and by cuttings as<br />

large as fenceposts 2 m long. Giowth is rapid. The species is not frost-hardy.<br />

The species is recognized by the pinnately compound leaves with 7-17 elliptical<br />

leaflets that are paired except at the end. It has narrow, flat, blackish pods<br />

and numerous showy, pea-shaped, whitish-pink or purplish-tinged flowers on<br />

old leafless branches or on the back of leaves.<br />

As the common name "mata-rat6n" (mouse killer) suggests, the toxic seeds,<br />

bark, leaves, and roots serve to poison rats, mice, and other rodents.<br />

The genus Gliricidiahas about 10 species of trees in tropical American including<br />

the West Indies. The Latin scientific names indicate its uses, the<br />

generic meaning "mouse killer," and the specific, "of hedges."<br />

Description Small deciduous tree to 10 n)high, with short trunk 20-30 cm<br />

in diameter, often twisted, and irregular spreading crown of thin foliage. Bark<br />

dish on exposure, hard, heavy, strong, coarse-textured, with irregular grain,<br />

pretty. Not easy to work but takes a good polish. Resistant to termites and<br />

decay. Is good fuelwood and serves for curing tobacco and for charcoal.<br />

Other Uses Used for posts, posts of rural houses, railway crossties, heavy<br />

construction. Suitable also for furniture, farm implements, tool handles, small<br />

articles.<br />

Commonly used as living fences. Posts set promptly after cutting generally<br />

sprout and take root, forming branches and lasting indefinitely. Can be<br />

trimmed frequently, and the branches used for green manure and cattle forage<br />

as well as firewood. Trees also used in firebreaks and windbreaks and for<br />

reforestation of denuded watersheds.<br />

Trees serve aho for shade in ,offee and cacao or cocoa plantations, for sup.<br />

port of vanilla and black pepper vines, and for shade and ornament. The<br />

names 'niadre de cacao" and "mother-of-cocoa," applied in some areas, indicate<br />

their use as shade trees in cacao plantittionS. These legumes have root nodules<br />

containing nitrogen-fixing bacteria which enrich the soil.<br />

Foliage browsed by cattle but toxic to horses and most other animals. In a<br />

few countries flowers eaten fried or boiled, though they may be poisonous<br />

raw. Leaves reportedly can hasten ripening of bananas. The flowers are a<br />

source of honey. Freshly crushed leaves used as poultices in home remedies.<br />

Natural Distribution From Mexico through Central America to Colombia,<br />

Venezuela, and Guianas in northern South America. Altitude from sea<br />

level to about 1600 in, mainly below 500 in.<br />

Planted also in southern Florida and in South America south to Brazil;<br />

becoming naturalized in West Indies. Introduced also in Old World tropics, including<br />

Africa, southern Asia, Indonesia. Brought to the Philippines by the<br />

Spanish in the seventeenth century and now thoroughly naturalized.<br />

Climate and Soils Hlumid tropical, with no frosts. Annual rainfall<br />

1500-2300 mm and above, mostly with a dry season. Soils various, moist or<br />

dry, including eroded, sand dunes, and limestone.<br />

44. Gmelina arborea<br />

Botanical Name Gnuelina arborea Roxb.<br />

Common Names gmelina (pronounced mie-EYE-na, English): melina (pronounced<br />

me-LEE-na, Spanish); yemane (Burmese and international); gainbhar,<br />

gumhar, kunihar (India); gamar (Bangladesh); etdemata (Sri Lanka);<br />

bulang (Malaya): bushbeech (Malaysia).<br />

Verbena Family, Verbenaceae<br />

Gnielina has become well known as a very fast-growing tree for arid and<br />

It can also be grown in plantations in humid tropical<br />

semiarid regions.<br />

lowlands. Thus, it is a promising fuelwood crop. Its silviculture iswell known,<br />

and its seeds are widely available. It can be propagated by the abundant seeds,<br />

coppice well and sprout<br />

by cuttings, or by budding or grafting. The trees<br />

stumps. Thus, gmelina is especially promising as a<br />

vigorously from cut<br />

fuelwood crop for plantations in humid lowland tropics, because it can be<br />

established easily and cheaply and regenerates well from both sprouts and<br />

seed.<br />

Because of international interest, the FAO Planel on Forest Gene Resources<br />

has included this species as one of top priority in the list of forest trees whose<br />

gene resources need exploration, utilization, and conservation. A provenance<br />

collection of seed samples from widely scattered areas indicates the genetical<br />

variation and the best seed sources for plantations in different environments.<br />

A large scale plantation was made at Jarilandia on Rio Jar, in Brazil's<br />

Amazon Basin, by Daniel K. Ludwig. Ile planned to grow Gnueina on a 6-or<br />

7-year rotation for pulpwood with 3 coppices before replanting. Recent reports<br />

not been very successful and that other tree<br />

indicate that the project has<br />

species are being grown.<br />

The genus Ginelina contains about 35 species of trees and shrubs, most in<br />

tropical eastern Asia, Indomalaysia, and Australia, and 2 in Africa. It was<br />

named for Johann Georg Gmelin 11709-55), a German botanist. Tile specific<br />

name from Latin means "treelike."<br />

This species is easily recognized by the large ovate, opposite leaves with 3 or<br />

5 main veins, clusters of many large, trumpet-shaped, orange-yellow flowers,<br />

and egg-shaped, orange-yellow fruits.<br />

Description Medium to large deciduous tiee 12-30 ni high and 60-100 cm<br />

in trunk diameter, of very rapid growth. Grows in the open with tapered trunk<br />

Bark light gray or grayoften<br />

bent, large low branches, and broad crown.<br />

yellow, smooth, thin, somewhat corking, becoming brown and rough; inner<br />

bark mottled, turning brown quickly upon exposure. Young lwigs, leafstalks,<br />

and lower leaf surfaces yellow-brown, softly hairy. Twigs stout, often slightly<br />

4-angled.<br />

Leaves opposite, broadly ovate and slightly heart-shaped, mostly large, 10-20<br />

Botanical Name Grevillea robusta A. Cunn.<br />

Common Names silky-oak, grevillea, silk-wak (English); southern silky-oak<br />

(Australia); grcvilea, roble de sedir, roble aostraliano (Spanish); carvalho<br />

sedosa (Brazil): mwangati (Tanzania); bahekar, bekkar (Pakistan).<br />

Protea F'amily, Proteaccae<br />

This handsone tree, native of Australia, has showy yellowish flowers and<br />

fernlike leaves that are silky and whitish on lowc r surfaces. GrevUllea, a large<br />

genus of about 190 species of shrubs and trees of Australia, Malaysia, and<br />

nearby islands, was dedicated to the Rt. Hon. Charles Francis Greville<br />

(1747.1809), a nineralogist and patron of botany and a founder of the Royal<br />

Horticultural Society of London. The specific name "robust" is appropriate for<br />

the largest tree among mostly shrubby species. The common name "oak" refers<br />

Iathe resemblance to that wood, while "silky"describes the lower leaf surface<br />

and freshly split wood.<br />

This species is fast-growing, cold-hardy, and drought-retsistant. It is easily<br />

propagated from the quantities of seeds and regenerates naturally, r.tning<br />

wild as an undesirable weed. It is widely planted fo timber and shade and<br />

could be "aluable for firewood. This is a fuelwood for the tropical highlands<br />

and the humid tropics.<br />

46. Guazuma ulmifolia<br />

Botanical Name Guazurna uhnifolia Lam.<br />

Synonym Guazuina tomentosa H.B.K.<br />

Common Names guAcima, guicirno, gudzuma, hudslmo (Spanish); caulote,<br />

cablote (Central America); guacimillo (Nicaragua); bay.cedar (Belize); West-<br />

Indian elm (Trinidad); jacocalalu (Virgin Islands); bois d'orme, bois de hetre<br />

(French); goeaazoema (Dutch West Indies); mutamba (Brazil); nipaltuntha<br />

(India).<br />

Chocolate Family, Sterculiaceae<br />

GuAcima is one of the most common trees in seasonal or dry forests within<br />

its native range throughout the humid tropics of the Americas. It is classed as<br />

an excellent fuel but is seldom cultivated. Gudcima is common in openings,<br />

clearings, pastures, along stream banks, and in secondary forests of disturbed<br />

areas. This hardy species grows rapidly and requires light. The seeds are scattered<br />

by wildlife and livestock, and the trees appear frequently along cattle<br />

trails. It is easily recogniwd by the 2 rows of finely saw-toothed ovate leaves<br />

having 3 main veins, the many small brownish-yellow flowers, and the round<br />

to elliptical, ver, warty, hard, black fruits.<br />

This variable species has differences in the shape and hairiness of the leaves<br />

and in the shape of the seed capsules and their method of opening. Trees in<br />

moist areas have nearly hairless foliage (rusty brown hairs, if present). Those<br />

in dry areas have light gray, densely hairy foliage and formerly were separated<br />

as a different species (Guaz.u na tomentosa 1I.B.K.).<br />

Guazurna has 3species cf trees, kll in tropical America. The generic name of<br />

American Indian origin has been adapted in Spanish with different spellings.<br />

The specific name means "with leaves lile Ulmus (elm)."<br />

Description Small to medium-sized tree, evergreen except in areas with<br />

long dry season, to 15 in high, sometimes larger, with trunk 30-60 cm in<br />

diameter and spreading rounded crown of long horizontal or slightly drooping<br />

slightly<br />

branches. lMArk gray or brown, becoming furrowed and rough or<br />

shaggy; inner bark light brown, fibrous, slightly bitter. Twigs covered with<br />

tiny rusty brown or light gray star-shaped hairs when young, becoming dark<br />

brown, long and slender.<br />

Leaves alternate in 2 rows in flattened arrangement, ovate to lance-shaped,<br />

6-13 cm long, 2.5-6 cm wide, long-pointed, finely saw-toothed, with 3 or<br />

or no!ched unequal-sided base, thin,<br />

sometimes 5 main veins from rounded<br />

nearly hairless or sometimes densely hairy, green upper surface, paler underneath,<br />

at night hanging vertically. Leafstalks slender, 6-12 mm long, covered<br />

with tiny star-shaped hairs.<br />

Flowerclusters (panicles) branched, 2.5-5 cm long at base of leaves. Flowers<br />

many, short-stalked, small, brownish-yellow, with 5 <strong>part</strong>s, about I cm long<br />

47. Haloxylon aphyllum<br />

Botanical Name Haloxylon aphyllum (Minkw.) Ilin<br />

Synonyms Haloxylon ammondendron (C. A. Mey.) Bunge var. aphyllim<br />

Minkw., Arthrophyturm aphylluin (Minkw.) Litw., Arthrophytum haloxylon<br />

Litw.<br />

Common Names black saksaul; saksaul, saksaul cheryni (Russian, spelled<br />

also saksaoul or saxaul; pronounced sik-sI-66ll; odzhar (Turkmeni).<br />

Goosefoot Family, Chenopodiaceae<br />

Black snksaul and the next species, white saksaul (Haloxylon persicuni), are<br />

halophytes, or salt-tolerant plants growing in salt deserts. Often forming pure<br />

stands, they occupy vast areas in the Soviet Union under severe conditions<br />

where most trees cannot survive.<br />

Haloxylon contains 10 species of shrubs and small trees that are halophytes.<br />

They have green, succulent, jointed stems that are apparently leafless. Haloxylon<br />

ranges through salt deserts and steppes from the Mediterranean region<br />

eastward through southern Asia to Mongolia and southwestern China.<br />

Haloxylon aphyllurn is both a xerophyte and halophyte, being tolerant of<br />

drought and salt in beth hot and cold deserts. As the leaves are reduced to<br />

scales, food is manufactut'd in the greenish twigs (cladodes).<br />

Growth obviously is slow. Year-old seedlings are planted. The taproots grow<br />

vigorously to as deep as 7 m to locate subsoil moisture. Under favorable conditions<br />

the trees form an open irregular crown of foliage and begin to bear<br />

flowers and fruits at 7 years. Life span is 50-70 years (rarely 100). In tests the<br />

plants have been coppiced at 50 cm height on a 5-year rotation.<br />

This genus is distinguished by jointed green stems that are freshy or succulent<br />

and brittle, leaves reduced to tiny green scales, and rounded fruit with<br />

5wings. The hard, heavy wood, which is almost comparable to coal, isof enormous<br />

importance for firewood and charcoal.<br />

The generic name for this species is from Greek words for "salt" and "tree."<br />

The specific name, meaning "without leaves," refers to the leaves reduced to<br />

tiny scales.<br />

Description Small tree 5-8 m high, trunk 20-40 cm in diameter generally<br />

having large irregular base, often with large branches of same diameter near<br />

base, with irregular open crown of curved or drooping ribbed branches,<br />

evergreen but appearing leafless, with deep taproot. Bark dark gray or graybrown,<br />

very thin, on light gray branches. Branches and twigs (cladodes) cylindrical,<br />

fleshy or succulent, greenish, hairless, brittle. Young twigs green or<br />

whitish, 2 mm thick, with rings at nodes.<br />

Leaves opposite or paired, tiny, scalelike, short, triangular, blunt, united in<br />

cuplike base.<br />

Flowers single and stalkless at base of scales on very short twigs at nodes or<br />

48. Haloxylon persicum<br />

Botanical Name Haloxylon persicum Bunge<br />

Common Names white saksaul; saksaul (Russian, pronounced stk-sd-ool);<br />

tar-gaz (Pakistan); ak-sazak (Turkmenil.<br />

Goosefoot Family, Chenopodiaceae<br />

White saksaul is a halophyte, or salt-tolerant plant, of salt deserts<br />

widespread in arid regions from Asia Minor to the Soviet Union. This common<br />

widespread species forms saksaul or Haloxylon woods in pure stands or with<br />

Haloxylon aphyllum on san.1hills and sand ridges. Together they occupy about<br />

100 million ha in the Soviet Union. This species is extremely drought-resistant<br />

and easily established. However, it is less resistant to cold and less salttolerant<br />

than Haloxylon aphyllui. It lives 20-25 years.<br />

Like black saksaul, this species is characterized by jointed green stems that<br />

are fleshy or succulent and brittle, and leaves reduced to tiny scales but longpointed<br />

instead of blunt. The hard, heavy wood is prized for firewood and<br />

charcoal. The specific name refers to Persia, now Iran, where this species was<br />

first noted. Minor varieties differing in leaf shape and fruit have been named.<br />

Description Shrub or gnarled small tree 1.5-4 in high (sometimes to 7 m)<br />

with stout trunk 10 cm in diameter, often branching at a height of 1 m or less,<br />

with irregular open crown of spreading t':anclies, evergreen but appearing<br />

leafless, with deep taproot. Bark light gray, thin. Branches and twigs<br />

(cladodes) cylindrical, jointed, fleshy or succulent, greenish, hairless, brittle.<br />

Young twigs pale green, 1-2 mm thick, with rings at nodes, upright. Older<br />

twigs whitish, often drooping.<br />

Leaves opposite or paired, tiny, scalelike, triangular, I mm long, very longor<br />

short-pointed, united in cuplike base hairy within.<br />

Flowers single and stalkless at base of scales on very short twigs at nodes or<br />

joints, tiny, greenish, composed of 5-lobed calyx, no corollr. 5 stamens and 5<br />

sterile stamens, and pistil with ovary and 5 styles.<br />

Fruits(utricles) rounded, flattened, 2-2.5 mn in diameter, fleshy, within the<br />

enlarged calyx 9-12 mm in diameter of 5 rounded membranous brown wings,<br />

-seeded.<br />

Wood very heavy (sp. gr. 1.01), brittle, breaks easily, not splintering,<br />

durable. An excellent fuel and extensively used for making charcoal. Almost<br />

comparable to bituminous coal: hurns down to long-smoldering cinders.<br />

Other Uses Produces valuable nutritious forage for camels and sheep in<br />

southern regions of Soviet Central Asia, <strong>part</strong>icularly in winter.<br />

Well-developed root system is excellent for sand fixation. Is adapted to sand<br />

dunes, but moving dunes must be stabilized with grasses first.<br />

Natural Distribution Asia Minor from Sinai, Israel, and Arabia to Iraq,<br />

Iran, Afghanistan, Soviet Union, and Mongolia in Central Asia. Mostly at low<br />

altitudes. Seldom planted outside the native range.<br />

Legume Family, leguminosae (Mimosoideae)<br />

The large genus Inlaf, froni the Tupi Indian narne, contains nearly 200<br />

species of trees in moist tropical and subtropical regions of the New World.<br />

The genus is easily recognized by the iany threadlike stamens in clustered<br />

flowers in the subfanily Mimosoideac. and within that subfamily by the<br />

leaves that are pinnately rather than bipinnately conpound.<br />

The trees commonly are grown for shade in plantations of coffee and cacao,<br />

and the wood serves for firewood and charcoal. The trees are easily prop.<br />

ngated from seed and are fast-growing. This species, whose Latin namne means<br />

"true" or "genuine," was the first namued in the large genus. Several varations<br />

originally designated as species have been united as synonyms or subspecies.<br />

Other species have similar uses for fuel, shade, and edible fruits. This species<br />

is a fuelwood for tropical highlands and the humid tropics.<br />

Legume Family, Leguminosae (Mimosoideac)<br />

Leucaena has numerous uses including excellent firewood and charcoal,<br />

timber, forage, organic fertilizer, reforestation, shade, and ornament. This<br />

very fast-growing shrub or small tree is apparently native to southeastern<br />

Mexico but has been widely introduced and naturalized throughout the<br />

tropics, often spreading as a weed. It is recognized by the bip!nnately compound<br />

leaves with many small, narrowly oblong, gray-green leaflets, flowers<br />

in many whitish balls, and many clustered flat dark brown pods.<br />

The genus Leucaena contains about 10 species of shrubs and trees in tropical<br />

and subtropical regions, nearly ell in New World; 2 are found as far north as<br />

the southern border of the United States in Texas. The generic name from<br />

Greek, "to whiten," and leucocephala, "white-head," both refer to the flowers.<br />

This species was long known as Leucaena glauca. This is a fuelwood species for<br />

the humid tropics.<br />

Description Size differing in varieties,<br />

from a rounded, very branched<br />

shrub less than 5 m high to a small or medium-sized slender tree 8-20 m high<br />

Natural Distribution Native apparently in southeastern Mexico<br />

(Yucatfn). Widely introduced and naturalized throughout the tropics. In the<br />

New World from southern Florida and southern Texas (also planted in California)<br />

south to Chile and Brazil and through the West Indies. In the Old World<br />

from Africa to southeast Asia, Australia, Philippines, and Pacific Islands to<br />

Hawaii. Altitude where planted mostly lowlands from sea level to 500 m or<br />

high as 750 m in Hawaii. In Hawaii, other vegetation crowded out by<br />

leucaena's widespread dense thickets through the dry lowlands. Thoroughly<br />

naturalized in roadsides and abandoned pastures in dry coastal regions of<br />

Puerto Rico.<br />

Climate and Soils<br />

Semiarid tropical with frost.free temperatures. Growth<br />

best where annual rainfall 600-1700 mm. However, the hardy plants can<br />

spread where rainfall as low as 250 mm. Soils a wide variety from rocky and<br />

coral to heavy clay. Growth better in neutral or alkaline soils rather than<br />

acidic.<br />

Botanical Name Melaleuca qiinquenervia (Cav.) S. T. Blake<br />

Synonym Mela!euca leucadendronauct., non (L.) L.<br />

Common Names cajeput-tree, paperbark, bottlebrush, white bottlebrush,<br />

punk-tree (English); broadleaved tea-tree, five-veined paperbark, maouli<br />

(Australia); cayeputi, cayeput (Spanish); corcho (Costa Rica); cajaputi<br />

(India); samed (Thailand); kayuputeh (Pen.Malaysia); kajuputih (Indonesia).<br />

Myrtle Family, Myrtaccae<br />

Cajeput-tree has been widely introduced as an ornamental throughout the<br />

tropics from its native home in eastern Australia and nearby islands. In many<br />

areas it has spread and has become naturalized as an undesirable weed.<br />

Where native, this species is common in open grassland in coastal savanna<br />

belt, especially along river banks and edges of tidal waters. It forms pure<br />

stands in swampy soils and is frequent on hillsides having ground water near<br />

the surface.<br />

Where introduced, the trees become common along highways, fencerows,<br />

ditches, swamps, :nd fields. The thick bark provides resistance to fires. The<br />

brittle branches are broken by strong winds. Sprouts are abundantly produced<br />

from stumps and roots. It is propagated from seeds or cuttings.<br />

The wood is an excellent fuei and is available where eradication is desired;<br />

plantations are not needed. This species (uaider its former name of Melaleuca<br />

ieucadendron)was named as a fuelwood iii all three climate categories of the<br />

Master List of Firewood Species in Firewood Crops. Thus, a description and<br />

illustration of this species are added here.<br />

This species is easily recognized by the odd whitish bark, which peels in<br />

many papery layers, the lance-shaped or narrowly elliptical leaves with mostly<br />

5 veins from base to tip, and the many crowded stalkless white flowers with<br />

numerous<br />

threadlike stamens suggesting a bottlebrush.<br />

Melaleuca from Greek words for "black and white" refers to the dark trunk<br />

and white branches of one species. The specific name, meaning "5.nerved,"<br />

describes the leaves. This genus has about 100 species of mostly large shrubs<br />

and small trees centered in Australia, with a few in New Zealand and nearby<br />

areas.<br />

Description Evergreen resinous small to medium-sized tree with poor<br />

form, 6-16 in high, with short trunk 30-cm in diameter, slightly angled and<br />

grooved, often crooked<br />

or twisted, with main axis and irregular branches<br />

forming narrow or open crown. With age a large tree 25-30 m high and 60-100<br />

cm in trunk diameter. Bark of trunk and branches whitish, very thick, corky<br />

or spongy, composed of many light pink, fibrous, papery layers, which split<br />

and peel, on large trunks becoming rough and shaggy; inner bark light brown,<br />

slightly sour.<br />

53. Mimosa scabrella<br />

Botanical Name Mimosa scabrella Benth.<br />

Synonym Mimosa bracaatingaHoehne<br />

Common Names bracaAtinga, bracatinga, abarAcaltinga<br />

Legume Family, Leguminosae IMimosoideae)<br />

Bracafitinga, a small tree little known outside its home in southern Brazil, is<br />

a good fast-growing source of fuelwood for the humid tropics. It has small<br />

bipinnately compound leaves with tiny leaflets, small flowers in whitish balls,<br />

and several small, narrow, flat pods covered with tiny warts and separating into<br />

joints that split open.<br />

Bracadtinga is characteristic of and almost iimited to the forests of ParanApine<br />

(Araucariaangustifolia (Bert.) 0. Ktze.) ci the planalto or plateau region.<br />

However, the range is not continuous. It is abundant as a pioneer in clearings.<br />

Pure dense stands of braca~itinga forests of secondary vegetation have become<br />

established through vast areas of the planalto after destruction and burning of<br />

the Parand-pine forests. Great quantities of seeds are produced and germinate<br />

well in burned areas, producing abundant seedlings.<br />

As early as 1930, F. C. Hoehne in Brazil called attention to this rapidly growing<br />

tree as an excellent source of fuel. As a result, forest plantations were<br />

established. Plantations are easily established by direct seeding. Growth is<br />

fast, as much as 15 m in height in 3 years. Trees have been harvested on rotationr,<br />

as short as 3 years.<br />

Seeds reportedly remain viable up to 3 years under normal conditions of<br />

temperature and humidity. Storage in cold chambers has been recommended.<br />

To obtain rapid and uniform germination, the seeds should be rcarified,<br />

heated for not less than 3 minutes, and sown immediately afterwards. Also,<br />

the seeds can be left to soak in water for 2 days before sowing to accelerate germination.<br />

The genus Mitnosa has about 400-500 species, mainly herbs and low shrubs<br />

and some trees. Most grow in tropical and subtropical America, but a few are<br />

found in Africa and Asia. The generic name Mimosa from Greek meaning "to<br />

imitate" or "a mimic actor" may refer to some species called sensitive plants.<br />

They imitate animals by moving and folding their leaflets when touched. The<br />

specific name, meaing "slightly rough to the touch," refers to the densely<br />

hairy foliage.<br />

Description Small to medium-sized tree 4-12 in high Isometimes to 20 m),<br />

with tall straight slender trunk 10-50 cm in diameter in forest, or short and<br />

branched, with dense rounded crown of gray foliage, or a large shrub. Bark<br />

whitish-gray, smoothish. Twigs densely scaly.<br />

Leaves bipinnately compound, small, with axis 3-11 cm long and 3-9 pairs of<br />

54. Muntingia calabura<br />

Botanical Name Muntingia calaburaL.<br />

Common Names strawberry-tree, Jamaica-cherry, calabur-tree (English);<br />

capulln, capulin blanco, capulin de comer (Spanish); memiso (Cuba); pasito<br />

(Panama); chitato, majagiiito (Colombia); majagiiillo (Venezuela); nigiiito<br />

(Venezuela, Ecuador); bolina (Peru); bois d'orme (Haiti); calabura, pau-deseda<br />

(Brazil); buah cheri, cherry-tree, Japanese.cherry (Peninsular<br />

Malaysia); datiles (Philippines).<br />

Elaeocarpus Family, Elaeocarpaceae<br />

This fast-growing small tree of tropical America is a handsome ornamental<br />

but has become a naturalized weed where introduced, such as in southeastern<br />

Asia. It is distinguished by the 2 rows of irregularly toothed, lance-shaped or<br />

oblong leaves with 3 main veins from a very 1-sided base, by the long-stalked<br />

flowers at leaf bases with 5 spreading rounded white petals, and by the reddish<br />

or yellowish, round, slightly sweet berries. This is a fuelwood species for<br />

the humid tropics.<br />

The plants grow readily in open areas from seeds and cuttings but are shortlived.<br />

This hardy species may reseed naturally and become an undesirable<br />

weed in fields and waste places. Thus, its proposed use as shade for livestock<br />

has been questioned.<br />

Muntingia, a genus of 3 species of trees in tropical America, was dedicated to<br />

the Dutch botanist and physician Abraham Munting (1626-83). Calabura is<br />

from Latin, meaning "long fiber." The name "strawberry-tree" is su 13ested by<br />

the white flowers and reddish fruits.<br />

Description Evergreen small tree 8-13 m high, with trunk 10-20 cm in<br />

diameter and short broad spreading crown of foliage with musky scent. Bark<br />

smooth, brown; inner bark whitish, fibrous. Twigs spreading nearly horizontal,<br />

gray with tiny star-shaped hairs when young, later turning brown.<br />

Leaves alternate in 2 rows in flattened arrangement, 5-10 cm long, 1-3 cm<br />

wide, lance-shaped or oblong, long-pointed, with 3 main veins from very<br />

1-sided or oblique rounded base, irregularly toothed, thin, green upper surface<br />

with soft hairs, gray-green underside covered with tiny :,tar-shaped hairs.<br />

Leafstalks short, about 5 mm long, hairy.<br />

Flowers 1-3 on stalks 2-3 cm long at leaf bases, 2-2.25 cm across, produced<br />

continuously. There<br />

are 5 narrow green sepals, turned back; 5 spreading,<br />

rounded, white petals 6-10 mm long, shedding same day; many short yellow<br />

stamens; and on a disk the greenish pistil with 5-celled ovary and 5 stalkless<br />

stigmas.<br />

Fruits (berries) round, reddish, or ye.lowish, 10-15 mm in diarmieter, with<br />

stigmas at tip and juicy light brown pulp, slightly sweet and edible.<br />

Wood with sapwood lighter in color than pale brown heartwood,<br />

lightweight, medium-textured, with irregular grain, very easily worked, but<br />

susceptible to decay. Used locally for firewood. Thoroughly dry wood ignites<br />

quickly, producing a high flame with intense heat and little smoke, leaving red<br />

glowing embers.<br />

Other Uses Also used locally for barrel staves. Wood considered potential<br />

source<br />

of paper pulp. Tough bark fibers served in making rope and baskets;<br />

flowers used in home remedies. Sweetish red berries edible but without distinctive<br />

flavor.<br />

Its main value is as showy ornamental and shade tree. Fas'.growing in full<br />

sunlight, continuously bearing white flowers and reddish berries from about<br />

age 2 years onward. However, irregular appearance, musky scent of foliage,<br />

and s-'atter of juicy fruits objectionable. Widely spreading limbs break in<br />

strong winds and may require annual pruning.<br />

Natural Distribution<br />

Native from southern<br />

Mexico south to Brazil,<br />

Bolivia, and Peru and in West Indies (Cuba, Jamaica, Hispaniola). Altitude<br />

from sea level to 1300 m.<br />

Introduced sparingly elsewhere in West Indies, such as Puerto Rico, and in<br />

southern Florida; escaping from cultivation. Planted also in Hawaii and<br />

through the Pacific islands. Naturalized in Southeast Asia (Thailand and Vietnam,<br />

for example) and Malaysia, where common and considered native.<br />

Humid tropical with annual rainfall of 1000-2000 mm.<br />

Climate and Soils<br />

Soils many types, including sand, sandy coral soils, limestone. Scattered in dry<br />

to moist thickets and secondary forests along slopes and valleys where native.<br />

a closely related species local in<br />

Related Species Muntingia rosea Karst.,<br />

Legume Family, Leguminosae (Caesalpinioideae<br />

This fast-growing hardy tree, native to tropical and subtropical America, is<br />

widely planted and naturalized as a weed in arid and semarid regions of the<br />

world. It is also found in the humid tropics. Thus, the hard wood is available<br />

for firewood and charcoal. Easy identification is by the smooth yellow-green<br />

trunks, branches, and twigs; distinctive leaves consisting of a very short axis<br />

ending in a spine and beai!ng 2 or 4 drooping, long, flat, yellow-green strips or<br />

streamers and many small leaflets that shed early; clusters of showy golden<br />

yellow flowers; and nearly cylindrical pods narrowed between seeds.<br />

This species produces seed abundantly and grows easily from seed, root or<br />

shoot cuttings, or air-layers. It is more frost-hardy than most subtropical trees;<br />

for example, it is planted in the southern United States. It is very droughtresistant<br />

and thrives in full sunlight but may not be adapted to wet climates. It<br />

can become an undesirable weed.<br />

The genus Parkinsonia, which has a second species in Africa, honors John<br />

Parkinson (1567-1650), a British botanist. The specific name means "with<br />

spines or prickles." "Jerusalem" in this and other plant names does not refer to<br />

the city in Israel but is a corruption from Italian of "girasol," meaning "turning<br />

toward the sun."<br />

Description Small spiny tree 4-10 m high, with short often crooked trunk<br />

to 40 cm in diameter, often branching near ground, with very open crown of<br />

spreading branches, and very thin drooping foliage; green throughout the year<br />

though appearing leafless after leaflets fall. Bark of trunk, branches, and twigs<br />

smooth, yellow-green or blue-green, on large trunks becoming brown and<br />

fissured or scaly; inner bark green and slightly bitter. Twigs slender, slightly<br />

zigzag, finely hairy when young, often with spines 3 or I remaining at nodes,<br />

including 2 short spines (stipules).<br />

Leaves specialized, alternate, actually bipinnately compound, consisting of<br />

very short axis ending in spine 1-2 cm long, and I or 2 pairs of long yellowgreen<br />

drooping side axes, strips or streamers 20-30 cm long and 3 mm broad,<br />

flat and slightly thickened. Each strip with 20-30 pairs of thin, oblong, green<br />

(French);<br />

Pine Family, Pinaceae<br />

Pinus (from the classical Latin name), with nearly 100 species, is the most<br />

widespread genus of conifers and the one with the most commercial value.<br />

Conifers (Coniferae), known also as softwoods, are represented by about 600<br />

species native mostly in temperate regions. They are important sources of<br />

as lumber and other wood products. They are<br />

resinous fuel as well<br />

distinguished from hardwoods (Dicotyledons) by seeds that are exposed or<br />

naked in cones and by the absence of flowers and fruits.<br />

Pines ate evergreen resinous trees with straight trunk and axis and rings<br />

(whorls) of horizontal or spreading branches that are conical to the spreading<br />

crown. The bark is mostly thick and furrowed and sometimes scaly. End buds<br />

are compound, containing smaller side buds. There are usually 2-5 needlelike<br />

leaves in a bundle with a sheath of scales at the base. Male and female cones<br />

are found on the same tree. Female cones mature in 2 years, with paired longwinged<br />

seeds exposed at the base of many overlapping hard cone.scales. The<br />

cones nroduce ouantities of pale yellow<br />

numerous, crowded, small male<br />

pollen.<br />

Steven, Pinushalepensis var. pityusa (Steven) Gordon<br />

Common Names brutia pine, Calabrian pine, Cyprus pine (English), maindano<br />

(Tanzania); kadi.<br />

Pine Family, Pinaceae<br />

This pine species of the eastern Mediterranean region is closely related to<br />

Pinus halepensis and often classed as a variety or synonym. It is distinguished<br />

by the longer leaves 2 in a bundle and by the mostly 2-4 upright or spreading,<br />

nearly stalkless cones. The resinous wood is a useful fuel. This is a fuelwood<br />

species for arid and semiarid regions.<br />

Pinus brutia was<br />

named for Calabria province (ancient name Brutium) of<br />

southern Italy, where it apparently was introduced. Pinus halepensis,the close<br />

relative from the western Mediterranean region, has often slightly shorter and<br />

thinner leaves, fewer cones in a cluster that are pointed back on stout stalks,<br />

and cone-scales raised with a horizontal ridge on the exposed end.<br />

Description Needleleaf, evergreen, coniferous, medium to large pine tree<br />

12-24 m high (rarely 30-36 ni), with straight trunk and thin irregular spreading<br />

crown, forming more than 1 circle of reddish or yellowish branches a year;<br />

resinous throughout. Bark brownish-gray, furrowed. Twigs reddish, becoming<br />

gray-brown, ending in winter buds wih many fringed scales curved back.<br />

Leaves 2 in bundle, needlelike, 11-15 (-18) cm long, 0.5-1.5 mm wide,<br />

slender, sharp-pointed, edges with tiny tceth, green with whitish lines on all<br />

surfaces; at base a sheath of persistent scales.<br />

Cones (female) mostly 2-4 (sometimes to 6), in a ring, upright or spreading<br />

Honduran pine, Bahaman pine, yellow pine (English); pino caribea, pino del<br />

Caribe, pino hondurefio (Spanish); pino macho, pino amarillo (Cuba); pino<br />

colorado (Central America); ocote blanco (Guatemala); pino de la costa (Honduras).<br />

Pine Family, Pinaceae<br />

Pinus caribaea has become one of the most important timber trees planted<br />

through the humid lowland tropics, because it can grow at sea level on poor<br />

sites. Firewood is easily obtained as a byproduct. Where native this species is<br />

common in pine forests, pure stands or with other pines, and scattered in open<br />

savannas and grasslands.<br />

This species is distinguished by the long needlelike leaves mostly 3 in a<br />

bundle and the shiny reddish-brown prickly cones opening at maturity. Pinus<br />

caribaea is a fuelwood species for humid tropics and tropical highlands.<br />

Description Needleleaf, evergreen, coniferous, large tree becoming 20-30<br />

m tall and 30-60 cm in trunk diameter (rarely to 45 m and 1.3 m); resinous<br />

throughout, with odor like turpentine. Axis straight, with thin pointed conical<br />

crown of regular circles of horizontal branches, becoming rounded or irregular.<br />

Bark gray to reddish-brown, rough, thick, with long scaly ridges or<br />

plates and deep furrows exposing reddish-brown inner bark composed of rings<br />

like wood. Branches gray-brown, rough and scaly. Twigs stout, whitish-gray.<br />

Winter buds cylindrical, with many long, narrow, reddish-brown scales<br />

white-fringed.<br />

Leaves crowded and spreading at end of twigs, mostly 3 (2-5) in a bundle,<br />

needlelike, 15-25 cm long, less than 1.5 mm wide, slightly stiff, sharp-pointed,<br />

slightly rough on edges from tiny teeth, dark or yellowish-green, with whitish<br />

lines on all surfaces; at base a persistent sheath of gray-brown scales.<br />

Copies (female) mostly in upper <strong>part</strong> of crown, mostly 2-4 in a ring (whorl)<br />

and 1-3 rings a year, short-stalked, narrowly conical when closed, 4-12 cm<br />

long, 2.5.4 cm ii. diameter, shiny reddish-brown, composed of many over-<br />

Iappag hard cone-scales, maturing second year, opening to release seeds, then<br />

shedding or remaining attached a few years. Cone-scales ending in ridge and<br />

prickle less than 1mm long. Seeds 2 exposed at base of cone-scale, with elliptical<br />

body 6 mm long, black, mottled gray, or light brown, and membranous<br />

brown wing 20 mm long, becoming detached or remaining attached. Male<br />

cones many, crowded in clusters mostly in lower <strong>part</strong> of crown, narrowly<br />

cylindrical, 20-40 mm long, red-brown.<br />

Heartwood reddish-brown and sapwood whitish, of varying thickness.<br />

Wood soft, moderately lightweight (sp. gi. 0.61-0.68), nonporous, with growth<br />

Pinusin the New World. Altitude from sea level to 12 m in Bahamas, to 280 m<br />

in Cuba, and to 1000 m in Central America.<br />

Widely introduced in forest plantations around the world in some 40 countries<br />

with tropical and subtropical climates. It has been predicted that large<br />

centers of plantations of this pine likely will be in Brazil, lowland tropical<br />

Africa, Queensland in Australia, Fiji, and possibly eastern India. Several other<br />

countries have smaller centers of development.<br />

Propagation from seeds and seedlings is easy, and growth is rapid. Inoculation<br />

of soils with fungi that form mycorrhizae on the roots may be needed.<br />

Volume tables for plantations have been prepared. According to tests, this<br />

3<br />

species can produce a mean annual increment of 17 to 37 m per ha.<br />

Pine Family, Pinaceae<br />

The most widespread pine of the Mediterranean region is hardy and<br />

drought-resistant. It is characterized by the needlelike leaves 2 in a bundle and<br />

6-10 cm long, by 1-3 cones pointed back on stout scaly stalks, and by conescales<br />

raised with a horizontal ridge. The resinous wood makes good fuel and<br />

has served for charcoal. This is a fueiwood species for arid and semiarid<br />

regions.<br />

Aleppo pine is a hardy drought-tolerant pine for the Mediterranean climate<br />

and hot dry regions. It grows rapidly with good form and regenerates freely<br />

after fires. However, for lumber production it is recommended only where<br />

more profitable species with wood of higher quality are not adapted.<br />

Common and scientific names are from Aleppo in northwestern Syria.<br />

However, this species is restricted to the coast in that area and does not grow<br />

as far inland as that city.<br />

Description Needleleaf, evergreen, coniferous, medium to large tree 15 m<br />

high {sometin'es to 27 in), with straight trunk 50-100 cm in diameter and open<br />

rounded crown of irregular spreading branches, often more than 1 circle a<br />

year, smaller on poor sites; resinous throughout. Bark smooth, silvery or<br />

ashy-gray, shiny, becoming furrowed, scaly, and reddish-brown. Twigs<br />

whitish or ashy-gray, slightly rough, hairless. Winter buds conical, with many<br />

brownish-white scales fringed and often bent back tt tip, not resinous.<br />

Leaves 2 in bundle, needlelike, 6-10 cm long, less than 1mm wide, slender,<br />

curved-twisted, sharp-pointed, edges with tiny teeth, light green, with whitish<br />

lines on all %urfaces;at base a sheath of persistent scales.<br />

conical, 6-10 cm long, symmetrical or nearly so, shiny reddisn or<br />

yellowish-brown, composed of many overlapping hard cone-scales, maturing<br />

second year, remaining attached and closed often for a few years. Cone-scales<br />

with exposed end 4-angled, raised with hoiizontal ridge, without a prickle.<br />

Seeds 2, exposed at base of cone-scale, with oblong brown body 6 mm long<br />

and pale brown wing more than 2 cm long. Male cones many, crowded, elliptical,<br />

6-8 mm long, yellow tinged with red.<br />

Heartwood yellowish.brown and sapwood yellow. Wood heavy {sp. gr.<br />

0.71), coarse-textured, nonporous, resinous. Resinous or pitchy wood makes<br />

good fuel and has served for charcoal.<br />

Legume Family, Leguminosac (Mimosoideae)<br />

This widely planted tree is native to tropical America. It has bipinnately<br />

compound leaves with only 4 oblong leaflets, paired slender spines at the base<br />

of most leaves, ball-like heads of many small white flowers, and curved or<br />

coiled pink to brown pods bearing several shiny black seeds mostly covered<br />

by pink or whitish edible pulp. The ti,-es are growa mainly for shade and ornament<br />

and have various useful products. Pithecellobiun dulce is a fuelwood<br />

species for arid and semiarid regions and also for the humid tropics.<br />

ais hardy species is readily propagated by cuttings and weeds. It is fastgrowing<br />

and drought-resistant, withstands heavy cutting, and coppices<br />

vigorously. However, it may spread and become an undesirable weed. Heavy<br />

windstorms may break the branches or topple the shallow-rooted trees.<br />

Spaniards early introduced this New World tree into the Philippines, where<br />

it became thoroughly naturalized. It was named and described botanically in<br />

1795 in Coromandel, India, where it had been further transported.<br />

The tropical genus Pithecellobium has 150 to 200 tree species, some with<br />

spines, and has 2 each north to southern Florida and southern Texas. The<br />

generic name, coming from Greek words meaning "ape's earring," refers to the<br />

coiled pods of some species. The Latin specific name meaning "sweet"<br />

describes the edible seed pulp.<br />

Description Small to medium-sized spiny tree 5-20 m high, with short<br />

trunk 30-60 cm (to 1 m)in diameter, trunk and branches often crooked, and<br />

broad spreading crrwn to 30 in across. Nearly evergreen but shedding old<br />

leaves as new one, appear. Bark light gray, smnoothish, becoming slightly<br />

rough and furrowed; inner bark thick, light brown, bitter or astringent. Tivigs<br />

slender and droopinj', a few very long, greenish and slightly hairy when<br />

young, becoming gray<br />

Leaves alternate, biinnately compound, with very slender green leafstalk<br />

1-3 cm long bearing tiny round gland near tip and 2 very short side axes (pinnae)<br />

3-6 mm long. Leaflets 4, nearly stalkless, 2 at end of each side axis, oblong<br />

moderately hard, heavy (sp. gr. 0.64), fine-textured. Strong and durable, takes a<br />

high polish but brittle and not easily worked. Wood widely used as fuel but<br />

smokes considerably and is not the best quality firewood.<br />

Other Uses In India trees planted for fuel for brick kilns. Also used for general<br />

construction, paneling, boxes, posts. This attractive tree planted along streets and<br />

highways for shade and ornament and for shelterbelts. Can be pruned and<br />

trimmed into thorny hedges and fences for livestock.<br />

Edible pulp around the seeds eaten fresh or made into a drink like lemonade.<br />

Greenish oil in seeds can be used for food or in making soap, after processing.<br />

Presscake residue rich in protein and may be used as stockfeed. Pods and leaves<br />

good forage for cattle, horses, sheep, and goats. Plants withstand heavy browsing.<br />

Hedge clippings often gathered for animal feed.<br />

Miscellaneous products include tannin and home remedies from the bark, a<br />

mucilaginous gum from wounded bark, and good-quality honey.<br />

Natural Distribution Native from northwestern Mexico (Baja California<br />

and Sonora) south through Central America to Colombia and Venezuela.<br />

Widely planted and naturalized in many tropical regions, for example, in warmer<br />

and drier larts of the Philippines and India. Formerly planted extensively in<br />

southern India for many purposes, especially fuel and hedges. Introduced into dry<br />

areas of tropical Africa and naturalized in the West Indies and Hawaii. Also in<br />

southern Florida.<br />

Climate and Soils Where native dry or semiarid subtropical and tropical<br />

with low rainfall. Altitude from near sea level to 1800 in. Annual rainfall where<br />

planted 450-1650 mm. Soils most types, including clay, limetone, sands, and<br />

brackish sands. Often common in dry thickets or forests on coasts, plains, and hillsides<br />

The genus Prosopis has about 40 species in warm<br />

World centered in Argentina and ranging north to Mexico and southwestern<br />

United States. There are 4 other species in the Old World, from tropical Africa<br />

to southwest Asia and India. It is widely cultivated and naturalized in other<br />

dry tropical regions. Natural distribution of the genus is shown in Figure 106.<br />

Prosopis, applied to this genus by Linnaeus, is an ancient Greek name of a<br />

plant with prickly fruit, apparently burdock. Mesquite, the English term for<br />

the New World species is from the Spanish "me quite" and the Nahuatl native<br />

for this genus, is that of the carob tree<br />

term. Algarrobo, the Spanish name<br />

Mediterranean region.<br />

This genus has small to medium-sized deciduous trees and shrubs of dry<br />

tropical, subtropical, and warm temperate zones, with short<br />

regions, and<br />

trunk and spreading crown of very thin foliage, mostly spiny. Twigs are often<br />

are<br />

zigzag and enlarged at nodes. The variable, straight spines from twigs<br />

paired stipules or scattered prickles.<br />

The bipinnately compound leaves are alternate or on short spur shoots, and<br />

have 1-4 1-7) pairs of side axes (pinnae); the leafstalk has a round gland at end.<br />

oblong or linear, not<br />

many, mostly paired leaflets are small, narrow,<br />

The<br />

toothed on edges, and mostly yellow-green on both surfaces; they sometimes<br />

shed early.<br />

At the leaf bases therm are cylindrical flower clusters (spikelike racemes) of<br />

many crowded, nearly stalkless flowers along an axis. The flowers are small<br />

and greenish-white. The calyx is short, bell-shaped and 5-toothed; the corolla<br />

10<br />

of 5 narrow petals is often united toward base and often hairy. There are<br />

separate threadlike stamens longer than the petals. The pistil has a narrow,<br />

stalked, hairy ovary and threadlike style.<br />

The narrow fruits of pods (legumes) are straight, curved, or spirally coiled,<br />

with spongy sugary pulp, not splitting open. Each of the several, beanlike, flattened,<br />

shiny brown seeds is enclosed in a 4-angled nutlike case.<br />

This South American tree has spines paired on twigs- leaves with 1-3 pairs of<br />

side axes (pinnac); numerous, very narrow leaflets, and long, narrow, flattened<br />

pods curved in a ring. Its valuable products include firewood, timber for<br />

construction and other uses, and pods for forage and human consumption. It is<br />

called "el Arbol" ("the tree") in northeastern Argentina because of its importance<br />

and abundance there. This is a fuelwood species for arid and semiarid regions.<br />

Description Medium-sized, deciduous, spiny tree 5-15 (-18) m tall, with<br />

short trunk 40-70 cm, sometimes I m or more in diameter, often twisted, and<br />

broad rounded crown of many large branches. Bark gray to brown, with long<br />

furrows, thin. Twigs slender, drooping, with infrequent paired spines 2-4 cm<br />

long at enlarged nodes or leaf bases on vigorous twigs; some varieties thornless.<br />

Leaves alternate, bipinnately compound, hairless, with axis 0.5-8 cm long<br />

and 1-3 pairs of side axes (pinnae) 6-14 cm long. Leaflets numerous, 25-50 pairs<br />

on each side axis, stalkless, very narrow (linear), 5-17 mm long and 1-2 mm<br />

wide, short-pointed or blunt at tip, gray-green.<br />

Flower clusters (spikelike racemes) few at leaf bases, 7-11 cm long. Flowers<br />

many, crowded, almost stalkless, regular, greenish-white to yellowish, about 5<br />

mm long, composed of cuplike calyx 1mm long, corolla of 5 petals 3 mm long,<br />

10 separate threadlike stamens 4-5 mm long, and pistil with hairy ovary and<br />

slender style.<br />

Fruits or pods (legumes) beanlike, long, narrow, curved or in a ring, 12-25<br />

(-30) cm long, 11-20 mm wide, 4-5 mm thick, very flattened, long-pointed,<br />

light yellow, with sweetish pulp, not splitting open. Seeds 12-30, bean-shaped,<br />

oblong, flattened, each in 4-angled case.<br />

Wood with yellowish-white sapwood and heartwood rose-brown with<br />

streaks, turning dark brown. Modciately heavy to heavy (sp. gr. 0.75-0.85),<br />

nedium-textured, interlocked grain, semi-:ing-porous with large vessels and<br />

growth rings slightly distinguished. Difficult to work. Firewood an important<br />

use. Surpassed in calorific value by uly a few tree species.<br />

Other Uses One of thc most usetil woods in its range. Timber highly<br />

valued for construction, doors, window frames, benches, billiard cues, shoe<br />

lasts, pegs, barrel staves. A former us,.! was paving blocks. leartwood yields<br />

good-quality tannic acid for curing fine skins.<br />

Pods excellent forage for cattle and other animals. Algarroba flour from<br />

ground or milled pods made into baked goods. Jellies, paste, arrope (wine),<br />

aguardiente, vinegar are other food products. Trees cultivated to limited extent,<br />

especially for windbreaks and roadside planting; very drought-resistant.<br />

Introduced into semidesert regions of Africa. Use in reforestation has been<br />

tested in Chile, Argentina, and elsewhere. Thornless varieties planted as ornamentals<br />

in southwestern United States.<br />

Climate Semidesert subtropical with high temperatures. Plants withstand<br />

mild frosts. Rainfall where planted in Africa 200.400 mm with 8-11 dry<br />

months a year.<br />

Varieties Three named varieties differ mainly in shape and size of leaflets<br />

and pods. Selection for cultivation in this variable species has been suggested;<br />

for example, taller trunks, increased truit production, and absence of thorns.<br />

The nomenclature of Prosopis chilensis has been confused. The specific<br />

epithet was from Chile, and the type locality was in the vicinity of Santiago.<br />

This obscure older name was revived as a substitute for Prosopisjuliflorabut<br />

instead replaces Prosopis siliquastrum. Thus, some introductions under this<br />

name were Prosopisjuliflora. Others, for example, to Hawatii, were Prosopis<br />

pallida.<br />

a noxious wecd. The plants spread into wheat and cotton fields by root sprouts<br />

and thus bccome undesirable weeds. This is a fuelwood species for arid and<br />

semiarid regions.<br />

Prosopisfarcta is sometimes placed alone in a distinct genus because of its<br />

short "swollen" or "fat" pods, not flattened. The specific name, meaning<br />

"stuffed, filled, or solid with soft tissue," refers to this character. A variety is<br />

Wood of this low shrub available in small sizes. Obviously prized for<br />

firewood where larger woody plants are absent. Taproots as much as 5 m deep<br />

apparently contain more wood than the branches.<br />

Other Uses This hardy shrub is browsed by sheep, goats, cattle, and<br />

camels. Livestock eat the pods and scatter the seeds but feed on the foliage<br />

only when young, because of the spiny branches. Listed as a good honey plant<br />

but suspected of causing hay fever. The roots and pods contain tannin.<br />

Natural Distribution North Africa (Tunisia, Algeria-rare, Egypt) and<br />

southwestern Asia including Cyprus, Asia Minor, Syria, Palestine, Iraq, Iran,<br />

Causia, Afghanistan, Pakistan, India (Punjab). Altitude from sea level to 1900<br />

mn.<br />

In Iraq this species formerly grew in dense impenetrable thickets more than<br />

2 m high, providing shelter for abundant wildlife. However, those thickets<br />

mostly destroyed by fuel gatherers, who continually cut plants back to the<br />

ground. Plants seldom grow higher than 0.5 m before cutting. In Egypt often<br />

grow hidden in sand with only the pods exposed.<br />

Climate and Soils Semiarid and desert, with low rainfall. :..apted to deep<br />

alluvial soils, espec'ally with shallow water table, but common on dry clay.<br />

Also on saline soils, sandy hillsides and dunes, and red marl banks.<br />

Widely distributed and common on dry plains, foothills, mountains, river<br />

valleys, seashores. Also around canals and wells. Covers immense tracts of<br />

barren land.<br />

Legume Family, Leguminosae (Mimosoideae)<br />

This hardy tree of the dry Pacific coastal region of South America has flower<br />

clusters much longer than its leaves, leaves with 2-4 pairs of side axes (pinnae),<br />

long, and long, narrow, nearly straight pods.<br />

small leaflets less than 8 mm<br />

The wood has various<br />

uses in addition to firewood and charcoal, and the<br />

pods are valuable forage for livestock. Prosopispallida is one of the most useful<br />

hntroduced trees of Hawaii, occupyirg dry barren lands.<br />

This species was long known in both Hawaii and Puerto Rico as Prosopis<br />

julilloraand for a shorter time as Prosopischilensis, when the latter, older name<br />

introductions under<br />

was thought to represent the same species. Thus, some<br />

may refer to Prosopispallida. The specific name refers to the<br />

those names<br />

a fuelwood species for arid and<br />

pallid or pale gray-green foliage. This is<br />

semiarid regions.<br />

Description Small to medium-sized deciduous tree 8-20 m high, usually<br />

spiny, with irregular short trunk to 60 cm in diameter, often angled and fluted,<br />

twisted, crooked, with widely forking branches, and with broad spreading,<br />

very thin, often flat-lopped crown. Bark gray-brown, finely fissured or deeply<br />

hairless,<br />

furrowed, inner bark orange-brown, fibrous, bitter. Twigs green,<br />

slightly zigzag, some enlarged nodes or leaf bases with 1-2 spreading spines to<br />

3 cm long; some trees without spines.<br />

Guava is extensively cultivated and naturalized through the tropics for its<br />

rounded yellow edible fruits from which paste and jelly are made. It is a good<br />

firewood source because of its abundance, natural propagation, and classificaweed.<br />

Psidium guajava is identified by the smooth,<br />

tion as an undesirable<br />

oblong, dull green leaves with many sunken parallel side veins, and by the<br />

large white flowers with 4 or 5 petals mostly single at leaf bases.<br />

The hardy trees invade pastures as troublesome weeds. Even in densely<br />

populated and urban areas, the plants continue to spread. Firewood cutting<br />

Fruit varieties are propagated by root cuttings. Growth<br />

a site with full<br />

cellent, and the plants coppice readily. The trees can occupy<br />

sunlight and can withstand <strong>part</strong>ial shading. Control is difficult, even with herbicides.<br />

This species has been declared a noxious weed in at least one country.<br />

for the humid tropics.<br />

Thus, guava is a good firewood source<br />

to<br />

The genus Psidium has about 150 species of trees and shrubs native<br />

tropical America including I in southern Florida. This late Latin name for the<br />

pomegranate was adopted by Carolus Linnaeus. The specific name is from the<br />

Spanish guayaba.<br />

Description Evergreen shrub or small tree 3-10 m high, with trunk to 20<br />

cm in diameter and broad spreading crown, often branching near ground and<br />

68. Robinia pseudoacacia<br />

Botanical Names Robinia pseudoacacia L.<br />

Common Names black locust, yellow locust, locust, false acacia, robinia<br />

(English).<br />

Legume Family, Leguminosae (Faboideae or Papilionoideae)<br />

Black locust of tile eastern United States is cited under tropical highlands in<br />

the Master List of Firewood Species in Firewood Crops and is added here. This<br />

temperate zone tree produces excellent firewood and charcoal and has been<br />

introduced into many <strong>part</strong>s of the world. It is easily identified by the paired<br />

brown spines along twigs; pinnately compound leaves with 7-19 elliptical dull<br />

blue-green leaflets having a tiny bristly tip; clusters of showy, pea.shaped,<br />

white flowers; and narrowly oblong, Ilat, thin pods.<br />

This species forms the black locust forest cover type, which is spotty but<br />

widespread, for example, as a pioneer on old fields, burned areas, and lands<br />

strip-mined for coal. Black locust is a minor component of other forest cover<br />

types with oaks (Quercus) and other hardwoods and in mixed stands with<br />

pines (Pinus).<br />

Black locust grows rapidly but is short-lived. Natural reproduction commonly<br />

is by root sprouts or suckers, which spread onto bare areas. The number of<br />

sprouts can be increased by injury to the plant or root system. Seed crops often<br />

are heavy, but germination of untreated seeds in nature is poor. Propagation is<br />

by planted seedlings, direct seeding, transplanting sprouts, and cuttings.<br />

This species is intolerant of shade and is shallow-rooted without a taproot.<br />

As a legume it increases nitrogen content of the soil by nitrogen-fixing bacteria<br />

on root nodules and by decomposition of leaf litter.<br />

Robinia pseudoacacia var. rectissimta Raber, shipmast locust, a clone of<br />

unknown origin, has become established in northeastern United States, mainly<br />

New England. It has a straighter trunk and greater resistance to insect<br />

borers and decay. Propagation is by vegetative nieans.<br />

Robinia commemorates Jean Robin (1550-1629) and his son Vespasian Robin<br />

(1579-1662), herbalists to French kings and introducers of this species to<br />

Europe. The genus has about 10 species of trees and shrubs, all in the United<br />

States except 1confined to Mexico. The specific name, an old generic name,<br />

means "false Acacia."<br />

Description Deciduous, spiny, medium-sized tree 15 m high, with forking,<br />

slightly angled trunk 30 cm in diameter, often crooked, and irregular open<br />

crown of upright branches; rarely a large tree to 30 in and 60 cm in diameter.<br />

Bark light gray, thick, deeply furrowed into long rough forking ridges. Twigs<br />

stout, slightly zigzag, angled, becoming hairless, often with paired stout brown<br />

spines 6-25 nn (from stipules) at nodes. Buds few together in leaf scar, tiny,<br />

brownish, hairy; no end bud.<br />

Leaves spreading in 2 rows, alternate, pinnately compound, 15-30 cm long.<br />

Legume Fa, aily, Leguminosac (Faboideae or Papilionoideae)<br />

This fast-growing small tree produces forage, firewood, pulp and paper,<br />

food, and green manure. It is a handsome ornamental and has served in<br />

reforestation. Sesbania grandiflora is recognized by the pinnately compound<br />

leaves with many oblong leaflets rounded at both ends, the giant white or red<br />

pea-shaped flowers, and the very long, narrow, flattened pods that are longpointed<br />

at both ends.<br />

This fuelwood species for humid tropics propagates easily from seed, seedlings,<br />

and cuttings. It has extremely fast growth in plantations. Vigorous<br />

sprouts are formed after cutting. This is a short-lived species. The specific<br />

name, meaning "large-flowered," refers to this distinctive feature.<br />

Description Deciduous or evergreen small tree to 10 m high, with straight<br />

trunk to 30 cm in diameter and spreading thin crown of few nearly upright<br />

branches. Bark gray, rough, deeply furrowed into thick plates, corklike; inner<br />

bark pink, slightly bitter. Young twigs finely hairy.<br />

Leaves alternate, pinnately compound, 15-35 cm long, with hairless or finely<br />

hairy axis enlarged at base. Leaflets 10-30 pairs, very short-stalked, oblong,<br />

2-4 cm long, 6-12 mm wide, rounded at both ends, thin, pale yellowish-green,<br />

nearly hairless except when young.<br />

Flower clusters (racemes) hanging at leaf base have 2-5 very large or giant<br />

white or red flowers 6-9 cm long from curved bud. Flowers pea-shaped, with<br />

unpleasant odor, composed of bell-shaped whitish calyx about 2 cm long,<br />

slightly 2-lobed with 5 shallow teeth; corolla of 5 white or red fleshy petals 6-9<br />

cm long, stalked at base, the oblong spreading standard shorter than others<br />

and curved back, 2 curved wings, and 2 united curved keel petals; 10 curved<br />

stamens, 9 united into tube and 1separate; and pistil with very narrow stalked<br />

ovary and slender style.<br />

Pods (legumes) very long and narrow, hanging down, 30-45 (-60) cm long,<br />

6-8 mm wide, flattened but slightly 4-angled, long-pointed at both ends, light<br />

brown, long-stalked, splitting open. Seeds 15-50, beanlike, elliptical, 5 mm<br />

long, brown.<br />

Botanical Name Syzygiurn cumini (L.) Skeels<br />

Synonyms Syzygium jambolanum (Lam.) DC., Eugenia culnini (L.) Druce,<br />

Eugenia jambolana Lam.<br />

Common Names jambolan, jambolan-plum, Java.plum, Malabar-plum,<br />

black-olum tree (English); mzambarau (Tanzania); jaman (Pakistan); jaman,<br />

jam, jambul (India); madan, naval (Sri Lanka): thabyebyi (Burma); jambolan,<br />

jiwat (Pen. Malaysia); obah (Sabah, Malaysia); duhat (Philippines).<br />

Myrtle Family, Myrtaceae<br />

Jambolan, native to southern Asia, is extensively planted in many tropical<br />

and subtropical regions for sl-ie and ornament as well as for the plumlike<br />

fruits. Classed as a humid tropics .-pecies, it produces excellent fuelwood. It is<br />

identified by the opposite, narrowly elliptical, leathery leaves, by clusters of<br />

many small white flowers on old twigs back of the leaves, and by many<br />

crowded, almost stalkless, oblong fruits that are dark purple to black and sour<br />

but edible.<br />

Jambolan is easily propagated from seed but can be rooted from cuttings.<br />

The plants are fast-growing and are vigorous after coppicing and pruning. The<br />

abundant fermenting fruits, which are widely disseminated by birds, can<br />

become litter and a nuisance. In some areas, such as Hawaii, the plants have<br />

become undesirable weeds, shading out forage plants.<br />

The genus Syz.ygium, often united under Eugenia, contains about 500 species<br />

of trees and shrubs in the Old World tropical and subtropical regions. The<br />

generic name is from Greek, meaning "paired or joined together." The specific<br />

name, "of cummin," refers to an Egyptian dwarf plant grown for its aromatic<br />

seeds used in flavoring.<br />

Description Small to large evergreen tree 13-30 high, with straight or<br />

crooked trunk 50 c:, -i n in diameter and crown of many branches. Bark light<br />

gray with darker patches, smoothish; inner bark with thin green outer layer,<br />

mottled light brown, astringent and bitter. Twigs light green, becoming light<br />

gray, slightly flattened, hairless.<br />

Leaves opposite, hairless, with slender light yellow leafstalk 1.5-2 cm long,<br />

narrowly elliptical, 7-13 cm long, 3-7.5 cm wide, abruptly short-pointed at tip,<br />

short-pointed at base, not toothed on edges, slightly thickened, leathery, dull<br />

light green, paler underneath, light yellow midvein and many fine, straight,<br />

parallel side veins close together, with many tiny gland-dots visible under a<br />

lens, pinkish when young, turning red before shedding.<br />

Flower clusters (cynies) on old twigs back of leaves, 5-6 cm long and wide,<br />

with many paired stout forks at nearly right angles, end flower opening first.<br />

Flowers many, small, about 7 mm long, slightly fragrant, nearly stalkless, with<br />

cuplike conical light green base (hypanthium) 3 mm long and broad, bearing<br />

on rim 4 tiny rounded calyx lobes, 4 white rounded concave petals more than<br />

also carts, boats, masts, oars, farm timbers, mine timbers, railroad crossties. In<br />

Hawaii used on a small scale as decorative veneer for manufacture of marquetry<br />

designs on place mats.<br />

Astringent bark has served in tanning and yields a brown dye. Bark, fruit,<br />

seed, and leaves utilized in native medicines.<br />

Widely planted for edible plumlike fruits varying in size and in flavor from<br />

sour to sweet with astringent taste that can be reduced by soaking in salt<br />

water. Fruits eaten raw; can be made into juice, jellies, syrup, vinegar, wine,<br />

tarts, puddings. Handsome trees cultivated also for shade, ornament, windbreaks,<br />

hedges. Popular along avenues in India. Flowers yield high-quality<br />

honey.<br />

Natural Distribution Native from India to Burma, Sri Lanka, Andaman<br />

Islands, and Thailand in southeastern Asia. Widespread through India.<br />

Altitude from sea level to 1800 ni.<br />

Extensively planted and naturalized in many tropical and subtropical<br />

regions of the world, including Philippines, East Indies, Australia, Africa.<br />

Thoroughly naturalized in Hawaii. Less common in the New World but scattered,<br />

as in southern Florida, West Indies (not Puerto Rico), Central America,<br />

Guyana.<br />

or less twisted and fibrous, diffuse-porous, growth rings indistinct, lustrous,<br />

rough, strong, brittle. Difficult to season and not durable.<br />

Used for firewood and charcoal; burns reasonably well though slow to catch<br />

fire and with high ash content. Not considered a good railway fuel. Green<br />

wood reportedly produces offensive odor when burned. Leaf litter and small<br />

branches burn poorly and slowly, perhaps because of their high salt content.<br />

This species is important in arid regions because of its availability where few<br />

other trees can exist.<br />

Other Uses Wood used for carpentry, farm implements such as plows,<br />

turnery, furniture, cabinetwork, boxes, ornaments. Bark and galls have served<br />

in tanning and in home remedies, and the twigs in basketry.<br />

Trees widely planted for shelterbelts and windbreaks in arid zones, being<br />

evergreen and effective year-round. Rows of tanarisks protect highways and<br />

railroads from wind and blowing sand. 'Trees also used for erosion control and<br />

to stabilize sand dunes with their deep and extensive root system.<br />

can be planted as firebreaks along highways and<br />

Strips of tarnarisks<br />

railroads. Dense salty litter prevents growth of other plants and does not burn.<br />

Salt secreted from foliage may increase salt content of the ground. Trees also<br />

grown for ornament and shade: can be pruned into screens and hedges.<br />

India-almond is recognized by horizontal branches in circles at different<br />

levels, large leathery leaves that are broadest toward tip, and turn reddish<br />

before falling, and elliptical slightly flattened fruits with hard fibrous husk and<br />

edible seed. The fast-growing trees are hardy along sandy seashores. This is a<br />

good fuelwood species for the humid tropics.<br />

The seeds, which float, are dispersed by ocean currents and also by fruiteating<br />

bats. Growth is fast. The trees tolerate salt spray and drought.<br />

Terininaliahas about 250 species of trees widespread in tropical regions. The<br />

generic name refers to the clustered terminal leaves at ends of branches, and<br />

that of the species is from the Malabar name "katapang." Many other species of<br />

smaller ranges merit testing locally for firewood production.<br />

Description Small or medium-sized tree 10-15 in high, with short trunk 30<br />

cm in diameter, sometimes much thicker and angled with slight buttresses,<br />

with horizontal branches in circles or rows at different levels on trunk, with<br />

flattened crown. Evergreen or in dry climates deciduous, shedding leaves<br />

often twice a year. Bark gray, smoothish, thin, becoming slightly fissured; inner<br />

bark pinkish-brown, slightly bitter and astringent. Twigs brown, finely<br />

hairy when young, slender but swollen at nodes.<br />

Leaves alternate but crowded together near ends of twigs, with stout finely<br />

hairy leafstalks 1-2 cm long. Leaf blades large, broadest toward tip (obovate),<br />

15-28 cm long, 9-15 cm wide, abruptly short-pointed or rounded at tip,<br />

gradually narrowed toward rounded or slightly notched base, not toothed on<br />

edges, slightly thickened, leathery, upper surface shiny green or dark green<br />

and hairless, underneath paler, often with fine brown hairs and with 2 glands<br />

near base, turning bright red, sometimes yellow, before shedding.<br />

Flower clusters (narrow racemes) at leaf bases, 5-15 cm long. Flowers<br />

many, small, slightly fragrant, greenish-white, 5-6 mm across, mostly male<br />

TREMA<br />

Common Names trema, charcoal-tree (English)<br />

Elm Family, Ulmaceae<br />

The genus Trenta has about 25 species of generally small trees in tropical and<br />

subtropical regions that are mostly humid. They are recognized by the 2 rows<br />

of short-stalked, alternate leaves on long slender twigs; the leaves, commonly<br />

having 3 main ve'ns from an unequal-sided base, are long-pointed and have<br />

toothed edges. Tiny greenish flowers, clustered at leaf bases, are inconspicuous<br />

and without petals. Male and female flowers are located on the<br />

or black fruit (drupe) is<br />

same or different plants. The juicy, I-seeded, pink<br />

name from Greek,<br />

small and rounded with the style at the tip. The generic<br />

me",ing "hole," refers to the pitted stone of the fruit.<br />

The fast-growing plants are pioneers on bare soil, such as clearings and roadsides.<br />

The soft wood is of limited value as firewood but serves for charcoal, as<br />

the common name "charcoal-tree" suggests.<br />

This handbook describes and illustrates 4 of the 5 Trema species that were<br />

treated as a unit in Firewood Crops. A key to these 4 species follows.<br />

75. Trema guineensis<br />

Botanical Name Trema guineensis (Schumach &Thonn.) Ficalho<br />

Common Names trema, charcoal-tree (English); pigeonwood, hopout<br />

(South Africa); ngomba-wuli (Sierre Leone); adaschia (Ivory Coast); tieku<br />

(Niger); kasisa (Uganda); mainga (Tanzania); mijamuni, mpefu (Malawi).<br />

Elm Family, Ulnaceae<br />

Widespread through tropical Africa, this species is closely related to Tremna<br />

orientalis of Asia and is also included under that species. The rounded fruits<br />

are 4.6 mm in diameter, mostly turning black. The specific name of<br />

geographic origin refers to Guinea. The common name "charcoal-tree" indicates<br />

one of its uses. This is a fueiwood species for the humid tropics.<br />

The trees are one of the fastest-growing in their range, growing as much as 2<br />

m in height annually when young but less later. The trees spread from seeds,<br />

which germinate rapidly, and from root sprouts. However, they are very<br />

short-lived, maturing at only 5 or 6 years.<br />

Description Shrub or small to medium-sized tree 6-12 m high (sometimes<br />

'to 20 in), with straight trunk to 30 cm (sometimes 60 cm) in diameter,<br />

spreading crown, evergreen or deciduous. Bark smooth, light gray, thin; inner<br />

bark very pale pink to white, turning brown nn exposure. Twigs brownishgray,<br />

with soft whitish hairs when young.<br />

Leaves alternate in 2 rows, narrowly ovate to oblong, 6-12 cm long, 2.5-5 cm<br />

wide, unequal-sided, ending in very long point, edges finely saw-toothed, with<br />

3 main veins from slightly notched or rounded base and 4-5 side veins prominent<br />

on under surface; slightly thickened, bright green, rough upper surface;<br />

p,'e green with soft whitish hairs underneath; turning yellow before shedaing.<br />

Leafstalk short, 4-8 mm long.<br />

Flower clusters (cymes) short, branched at leaf bases. Flowers many,<br />

crowded, nearly stalkless, tiny, 3 mm wide, yellow-gree,, with calyx of 5<br />

hairy sepals and no petals, mostly male and bisexual or female in different<br />

clusters on same<br />

tree. Male flowers have 5 stamens opposite sepals; female<br />

flowers have pistil with 1-celled ovary, I ovule, and 2 short styles.<br />

Fruits (drupes) many on very short stalks, rounded or egg-shaped, 4-6 mm<br />

in diameter, with calyx at base, turning from green to dark purple or black,<br />

juice. Seed (stone) round, pale brown, hard.<br />

Wood whitish, faintly tinged with pink, without distinct heartwood, with<br />

large pores and annual growth rings, lightweight (sp. gr. 0.5), soft, perishable.<br />

Wood widely used for fuel and charcoal, as indicated by the name "charcoaltree."<br />

Other Uses Used for fruit boxes and poles. Strong cord made from bark.<br />

Shavings from inner bark rubbed on fishing lines as a preservative. Brown dye<br />

obtained from leaves; ashes from leaves have served in soapmaking.<br />

Chopped young leaves and fruits reportedly edible. Birds and bats eat juicy<br />

dry.<br />

Very common as a pioneer in secondary deciduous forests, forest borders,<br />

clearings, old farms. Also river banks, stream beds, valleys.<br />

Related Species Closely related to Trena orientalis (L.) Blume of Asia (No.<br />

77 here) and included under that species by sonic specialists. However, the<br />

range of the combined species would be very large and would include<br />

geographical variations. The separate name for the African variation is helpful<br />

in identifying the seed source.<br />

Botanical Name Trema politoria (Planch.) Blume<br />

Common Names banharria, khagshi, tila, kharkas (India); khakshi (Nepal).<br />

Elm Family, Ulmaceae<br />

This subtropical small tree of India and nearby areas grows insa drier climate<br />

than related species and may be more hardy and drought-rdsistant. It is<br />

distinguished by the very rough leaves with 3 main veins from slightly above<br />

the rounded base and by ,he small elliptical fruits 3 mm long.<br />

This species has very rapid growth from seed and has been proposed for af­<br />

forestation trials. It is suitable for planting on denuded and disturbed areas<br />

and as a soil binder. It is common as a pioneer on bare soil of open and disturbed<br />

areas including clearings, roadside cuts and embankments, landslides,<br />

and stream banks and beds. This species is abundant locally in open forests<br />

and is found along streams and in valleys. Trema politoria is a fuelwood species<br />

for the humid tropics and perhaps semiarid regions.<br />

Description Small evergreen tree 5 m high with short trunk 10 cm :n<br />

diameter and few spreading branches. Bark greenish-white or reddish-brown,<br />

thin, smoothish or becoming rough, with longitudinal fissures; inner bark red,<br />

fibrous. Twigs stout, rough with long, stiff, whitish hairs.<br />

Leaves alternate in 2 rows, oblong or lance-shaped, 5-15 cm long, 1.5-5 cm<br />

wide, ending in very long point, with sides almost equal, edges finely sawtoothed,<br />

with 3 main veins from slightly above rounded base and 6-7 veins on<br />

each side, slightly thickened, very rough on both surfaces with scattered hairs<br />

and raised bases of fallen hairs, shiny green upper surface, paler underneath.<br />

Leafstalk 5-10 mm long.<br />

Flower clusters (cymes) compact, branched at leaf bases. Flowers several,<br />

tiny, 3 mm wide, greenish, with calyx of 5 narrow hairy sepals, mostly male<br />

and bisexual or female in different clusters on same tree. Male flowers in short<br />

clusters with 5 stamens opposite sepals; female flowers in slightly larger<br />

clusters have pistil with hairless ovary and 2 spreading hairy styles.<br />

Fruits (drupes) several, elliptical, 3 mm long, with calyx at base, black,<br />

juicy, with I seed (stone).<br />

Wood gray-brown or reddish.brown, soft or moderately hard, moderately<br />

fine-textured, fibrous, with small pores, annual growth rings. Splits and cracks<br />

in seasoning. Used for fuelwood.<br />

Other Uses Rope made from fibrous bark; branches lopped for fodder.<br />

Very rough leaves used like sandpaper to polish wood and horn. The appropriate<br />

specific name from Latin means "polisher."<br />

Natural Distribution Through subtropical northern and central India<br />

from Gujarat in the west to Assam in the east; also Pakistan. Altitude from sea<br />

Buckthorn Family, Rhamnaceae<br />

This hardy spiny shrub or small tree, native to southern Asia, is cultivated<br />

throughout the tropics for its edible elliptical or rounded reddish fruits. It is<br />

also a fuetwood species for arid and semiarid regions.<br />

Its elliptical leaves are rounded at the tip and finely wavy-toothed on the<br />

edges; under surfaces of leaves have dense, %hitish, soft hairs. Small starshaped<br />

yellow flowers are clustered at leaf bases.<br />

This species is propagated by direct seeding or vegetatively, such as by grafting<br />

in the fruit varieties. Thornless varieties are known. The trees grow fast,<br />

coppice well, and sprout vigorously from stumps and roots. This species can<br />

be planted in dry areas and on poor sites unfit for other crops.<br />

The genus Ziziphus has 100-150 species of trees and shrubs widespread in<br />

tropical and subtropical regions including Australia and north to southwestern<br />

from Persian. The<br />

United States. This ancient Greek name was derived<br />

specific name, meaning "Mauritian," refers to Mauritania in northwestern<br />

Africa, where this tree was introduced long ago.<br />

MANGROVES<br />

Botanical Names Rhizophora, Bruguiera, and Ceriops in Mangrove Family,<br />

Rhizophoraceae; Avicennia in Avicennia Family, Avicenniaceae; Conocarpus<br />

and Lagunculariain Combretum Family, Combretaceae; Sonneratia in Sonneratia<br />

Family, Sonneratiaceac; etc,<br />

Common Names mangrove (English); mangle (Spanish); manglier (French);<br />

mangue (Portuguese); mangro, mangel (Dutch); Mangelbaum (German).<br />

The term "mangrove" is applied to as many as 50 tree species in about 13<br />

genera and 8 families. These trees form the mangrove swamp forests of silty<br />

seashores widespread throughout tropical regions. As indicated above, some<br />

species are closely related, whilk others are ,'assified in several unrelated<br />

plant families. The Old World tropics have a greater richness of species than<br />

the New World, which has only 4 genera in 3 families.<br />

Firewood Crops treats the mangroves together as a group for the humid<br />

tropics. This handbook describes and illustrates 10 species of mangroves<br />

belonging to 7 genera and 4 families; they are arranged alphabetically by<br />

botanical name.<br />

This introduction to mangroves contains general notes<br />

on the group, in-<br />

cluding characteristics, natural distribution, and ues. Next follows a key to the<br />

10 species described here.<br />

Mangroves produce good fuelwood in a readily accessible narrew coastal<br />

zone where other trees cannot exist. These trees are easily harvested by water.<br />

Natural regeneration is successful, and growth generally is rapid. Thus,<br />

firewood can be removed at intervals under management without establishment<br />

of plantations. Some species respond to cutting by sprouting from buds<br />

along the trunk and branches. Forests can be extended by vegetative propagation.<br />

These trees are pioneer plants on the bare depositing silt shores or mud flats.<br />

They are tolerant of salt water and brackish water. Many species have special<br />

adaptations that also aid in identification. Some have stilt roots or prop roots,<br />

often branched, that serve to anchor and to expand the forest. Roots of others<br />

rise above the water as pencillike projections or spongy "knee-roots"<br />

(pneumatophores), which function as aerators to absorb air. Some have seeds<br />

that germinate on the tree before falling or seeds that can float and germinate<br />

in salt water.<br />

Mangrove wood is prized for firewood and charcoal in many countries. It<br />

burns well when freshly cut, and the bark makes excellent fuel. The wood of<br />

most species is heavy and splits easily. It has a high calorific value and leaves<br />

little ash. Other uses of mangrove wood include marine pilings, furniture,<br />

wood chips for pulp and rayon, and extractives such as tannins and resins.<br />

As pioneers, mangroves tend to spread into open water, collect silt, and extend<br />

shore lines, thus increasing the land surface area. Other uses of mangrove<br />

Avicennia Family, Avicenniaccae (or Verbena Family, Verbenaceac)<br />

The genus Avicennia is recognized by lance-shaped leaves having fine gray<br />

hairs underneath and by upright, headlike clusters of flowers with a tubular,<br />

4-lobed, white or yellow corolla 10 mm across. The fruit is an egg-shaped flatupright<br />

pencillike projections (pheumatophores)<br />

tened capsule. Numerous<br />

rise from the roots. This is the norlhernmost and hardiest mangrove of the<br />

New World.<br />

the<br />

Avicennia germinans is common in mangrove swamp forests, mainly on<br />

landward side, in brackish water in mud flats of tidal zones of protected silty<br />

shores, and at the mouths of rivers. It is usually found with other mangrove<br />

species, rarely forming pure stands. This species penetrates farther inland<br />

along rivers and Lppears to withstand prolonged flooding.<br />

The name of the genus Avicennia, with about 10 species on tropical shores of<br />

or Abu Ali Huthe<br />

world, commemorates Abu Sina (Latinized as Avicenna),<br />

sian ibn-Abdallah ibn-Sina (980-1037), of Bokhara, a Persian physician, mathe­<br />

"germatician,<br />

philosopher and naturalist. The specific name, meaning<br />

minating," refers to the early seed germination often within the fruit on the<br />

tree.<br />

eDescription Evergreen shrub or small tree 3-12 in high Irarely to 25 i)<br />

spreading branches. Masses of small air roots 15-45 cm long sometimes hang<br />

in the air from upper <strong>part</strong> of large trunks. Numerous, upright, fleshy pencillike<br />

projections (pneumatophores) often rise 5-10 cm from the long horizontal<br />

roots in mud under tree, perhaps aiding in air movement. Bark dark gray<br />

or brown and smooth on small trunks, becoming dark brown, fissured, scaly,<br />

and thick; inner bark bright orange to yellow and within brown, slightly salty<br />

in taste. Twigs gray or brown, finely hairy when young, with rings at enlarged<br />

Avicennia Family, Avicenniaceae (or Verbena Family, Verbenaceae)<br />

This widespread Old World species of Avicewnia is distinguished by opposite<br />

leaves with fine gray hairs underneath, headlike clusters of small<br />

ovate<br />

the 4-lobed white corolla, an egg-shaped flattened capflowers<br />

5 mm across<br />

sule fruit, and numerous upright, pencillike projections from the root. .<br />

Avicennia marina is common and often the dominant species in mangrove<br />

swamp forests and salt marshes in mud flats of tidal zone:; along silt shores and<br />

along adjacent river banks at sea level. It is often a pioneer in mud,<br />

esta|llishing by other unrelated species. This<br />

i forest, and being follewed<br />

species is also found in mature mangrove forests in brackish water in a zone<br />

farthest away from the shore. Because it is not tolerant of shade, it gradually<br />

disappears in dense forests. The largest size is attained where drainage is good.<br />

This very variable species is one of the 5 mangroves of South Africa and the<br />

name "marine" refers to the<br />

southernmost, thus t~ie hardiest. The specific<br />

habitat. Five varieties differ in details such as leaf shape and size and in size of<br />

flower cluster, as well as geographical distribution.<br />

Combreturn Family, Combretaceac<br />

This mangrove is recognized by the elliptical leaves rounded at both ends<br />

and often notched at the tips, leafstalks with 2 raised gland-dots, small bellshaped<br />

whitish flowers with 5 tiny petals, ilar-shaped flattened fruits with 5<br />

tiny sepals remaining at the tips, and the upright pencillike projections often<br />

rising from roots.<br />

This species, found only in the New World and western Africa, is common<br />

in mangrove swamp forests of tropical shores with other species of mangroves<br />

and is often the most widely distributed. Flowers and fruits may be produced<br />

at less than 2 years. Growth is rapid. After cutting, a clump of many stems<br />

may sprout.<br />

Laguncuaria is from Latin, meaning "asmall flask or bottle," and refers to the<br />

fancied resemblance of flower and fruit to a bottle. The specific name<br />

"racemose" refers to the branching flower clusters. This genus has only I or 2<br />

species.<br />

Mangrove Fainl'y, Rhizophoraceac<br />

Rhizoluhrc, red mangrove, is perhaps tile most common and most widely<br />

distributed of the genera of mangrove swamp forests. Trees are recognized by<br />

the large branchy and arching stilt roots bordering the ocean, the small<br />

yellowish flowers with 4 sepals curved back on the fruit, the long cigar-shaped<br />

seedling hanging down, and blunt-pointed leaves.<br />

Trees of the genus Rhizophora are the most common mangroves in the New<br />

World and are also found in western AfriLa and Oceania. They are common to<br />

abundant in mangrove swamp forests over large flat areas of silty or muddy<br />

shores in salt and brackish water. Trees form pure stands on the seaward side<br />

and mixed stands with other mangrove species farther inland. Rhizophora with<br />

its stilt roots growing in shallow water extends farther seaward than other<br />

nangroves.<br />

The genus Rhi'oplhora has about 5 species on tropical shores. The generic<br />

name from Greek, meaning "root-bearing," refers to the prominent arching<br />

prop roots. The specific name is the Spanish common name for mangrove.<br />

Description Small to large tree of mangrove swamp forests 5-20 m<br />

(sometimes to 30 m) high with upright trunk 20-50 cm in diameter (sometimes<br />

to 70 cm), casily recognized by the branched, curved and arching stilt roots<br />

2-4.5 m high in salt water: sometimes a large shrub. Bark gray or gray-brown,<br />

smooth and thin on small trunks, becoming furrowed and thick; inner bark<br />

reddish or pinkish, with slightly bitter and salty taste. Twigs stout, gray or<br />

brown, hairless, with ring scars at nodes, ending in long narrow pointed green<br />

bud 2.5-6 cm long.<br />

Leaves opposite or paired, elliptical, blunt-pointed at tip, short-pointed at<br />

base, edges slightly rolled under, without visible veins, thick, leathery,<br />

hairless. 6.12 cm long, 2.5-6 cm wide, shiny green upper surface, yellow-green<br />

and black-dotted underneath. leafstalk 1.5-2 cm long. Paired narrow stipules<br />

at base of each leaf pair form narrow bud and shed, leaving ring scar.<br />

Flowers mostly 2-4 on forked stalk 4-7 cm long at leaf base, pale yellow,<br />

about 2 cot across, slightly fragrant. lell-shaped pale yellow base (hypanthiutm)<br />

about 5 mn long bears 4 widely spreading, narrow, leathery, pale<br />

yellow sepals 12 mill hog, which become enlarged and curved back and remain<br />

on fruit: 4 narrow thin petals I cm long, curved downward, whitish but<br />

turning brown, white woolly or cottony oil inner side, and 8 stalklesE stamens.<br />

90. Sonneratia caseolaris<br />

Botanical Name Sonneratia caseolaris (L.) Engl.<br />

Synonym Sonneratiaacida L. f.<br />

Common Names crabapple mangrove, mangrove (English); orcha (India);<br />

kirilla, kinnai (Sri Lanka); berembang (Pen. Malaysia); padada, pagatpat<br />

(Philippines); pedada, perepat, bedada (Malaysia); bidada (Java).<br />

Sonneratla Family, Sonneratiaceae<br />

Sonneratia, one of the minor genera of mangroves found along Old World<br />

tropical silty shores, is adapted to cutting for firewood because of its rapid<br />

regrowth from buds along the trunk and branches. The genus is characterized<br />

by very long, shallow, horizontal roots, from which arise many vertical "kneeroots"<br />

or "breathing-roots," which bear many fine horizontal "nutrition-roots"in<br />

the water. There are a few large flowers with many stamens. The fruit, having<br />

an ill-smelling pulp, is a rounded berry with calyx lobes spreading horizontal.<br />

ly.<br />

Soneratia caseolaris is common in mangrove swamp forests of silty shores,<br />

generally in less salty <strong>part</strong>s. This species is often found along tidal streams<br />

with slow-moving brackish<br />

or fresh water and as far inland as the salt water<br />

floods. Sonneratia is easily accessible in mangrove forests for firewood from<br />

wild stands. Because the trees recover rapidly after branchwood is cut, plantations<br />

should not be needed.<br />

This genus was dedicated to Pierre Sonnerat (1748-1814), a French naturalist<br />

and explorer. The 5 species are distributed from East Africa to southeastern<br />

Asia, northern Australia, the Philippines, and other western Pacific islands.<br />

Description Small to medium-sized evergreen tree of mangrove swamp<br />

forests 5-15 in high (rarely 20 m), trunk without buttresses or stilt roots, with<br />

rather open spreading crown, hairless throughout; or a shrub. "Knee-roots"<br />

(pneumatophores) 50-90 cm high, 7 cm in diameter. Bark gray, coarsely flaky.<br />

Twigs drooping, bluntly 4-angled when young, with rings at nodes.<br />

Leaves opposite, without stipules, with very short stout leafstalk, elliptical,<br />

oblong or ovate, 5-13 cm long, 2-5 cm wide, with broad or tapering base and<br />

biunt or rounded tip, not toothed on edges, stout midvein with 8-12 widely<br />

spreading fine side veins on each side, leathery, light green upper surface,<br />

paler underneath.<br />

Flowers 1-3 at end of drooping twig, from broadly elliptical bud, opening at<br />

sunset, nocturnal, short-lived, with disagreeable odor. The cup-shaped base<br />

(hypanthium) bears 6-8 calyx lobes greenish or yellowish-white on inner surface,<br />

persistent and spreading horizontally on fruit; petals 6-8, 2-3.5 cm long,<br />

1.5-3.5 mm wide, dark or blood-red, shedding early; stamens numerous, with<br />

threadlike filaments 2.5-3.5 cm long, red in lower <strong>part</strong> and white beyond;<br />

pistil with 16-21-celled ovary containing many ovules, and very long stout<br />

style. Flowering throughout the year.<br />
