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 />
OiII
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 />

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 />

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 />

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 />

COMMON FUELWOOD CROPS
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 />

rounded, flattened, blackish-brown.<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 />

thickets.<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 />

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 />

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 />

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 />
crowded, tiny, narrow leaflets 1-5 mm long, bluish gray green, finely hairy.<br />
Flower clusters (heads) like balls, in masses over tree, 1-4 on slender stalks<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 />

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 />

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 />

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 />

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 />

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 />

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 />

Birch Family, Bctulaceae<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 />

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 />

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 />

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 />

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 />

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 />

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 />

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 />

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 />

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 />

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 />

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 />

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 />

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 />

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 />

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 />

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 />

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 />

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 />

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 />

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 />

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 />

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 />

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 />

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 />

general electrification and gasification of populated areas its use now limited.<br />
Other Uses Foliage browsed by livestock. In the southern regions species<br />
important as winter forage for camels and sheep. Planted in grasslands to increase<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 />

After softening in boiling water, seeds strung as beads into necklaces,<br />
bracelets, decorations on hats, and curiosities for tourists. Young pods cooked<br />
as a vegetable, and seeds prepared as a coffee substitute. Bark and roots<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 />

(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 />

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 />

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 />

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 />

Common Names Caribbean pine, Caribbean pitch pine, pitch pine,<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 />

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 />

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 />

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 />

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 />
hairless throughout.<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 />

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 />

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 />

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 />

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 />

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 />

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 />

Classed as an excellent fuel, burning well.<br />
Other Uses Used in construction, including posts, beams, rafters, panels;<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 />
Climate and Soils Humid tropical and subtropical with high rainfall.<br />
Where introduced, annual rainfall varies from 1500 to 10,000 mm. Soils many<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 />

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 />

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 />

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 />

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 />
in diameter (often crooked), and rounded crown of<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 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 />

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 />
