1 Gardens Etlingera Giseke Bulletin of Java Singapore 59 (1&2): Etlingera Giseke of Java A.D. POULSEN Royal Botanic Garden Edinburgh, 20A Inverleith Row Edinburgh EH35LR, Scotland Abstract Nine species of Etlingera Giseke are known in Java, though two of them have not been collected recently. An identification key is given, along with descriptions, illustrations, and notes on local names, uses, and ecology. The conservation status of each species is assessed. Two species remain enigmatic and the remaining seven, including E. parva, which is synonomized with E. brachychila, are all found in Borneo, Sumatra and/or the Malay Peninsula. Introduction The genus Etlingera Giseke (Zingiberaceae) is an Indo-Pacific genus especially rich in species in the perhumid forests of Thailand, Malaysia, Indonesia and New Guinea. Many species are useful to man as food, condiment, medicine or as ornamentals. They also play an important role in the understorey as a food source for animals. The leafy shoots can be up to 8 m tall and often dominate gaps in disturbed forests. In Java, Etlingera may be confused with other genera that have radical inflorescences: Amomum Roxb., Hornstedtia Retz. and Zingiber Mill. Etlingera is, however, distinguished from all these by having a staminal tube. Blume (1827), described five ginger species from Java which are included in the present paper as Etlingera coccinea (Blume) S. Sakai & Nagam., E. foetens (Blume) R.M.Sm., E. hemisphaerica (Blume) R.M.Sm., E. solaris (Blume) R.M.Sm., an E. walang (Blume) R.M.Sm. At that time, E. elatior (Jack) R.M.Sm. had already been collected in Sumatra and described. Subsequently, E. megalocheilos Griff. was described from Peninsular Malaysia (Griffith, 1851) and Valeton (1904) documented its presence in Java with useful information also on other species of Etlingera there. Valeton published further observations and clear and informative illustrations in In 1921, he described what is here included as E. heyniana (Valeton) R.M.Sm. and E. parva (Valeton) R.M.Sm. Since then no further species of

2 146 Gard. Bull. Singapore 59 (1&2) 2007 Etlingera has been described from Java and thus the revision by Bakhuizen f. (1958; 1968) includes a total of nine species. In the present treatment, seven of these at least are good species but two remain somewhat mysterious. Material and Methods Measurements of plants follow Poulsen (2006). Only recent collections are cited in the present paper. As new flowering material will be collected allowing detailed measurements, a wider range can be expected for some of the character measurements included below. This is demonstrated by the variation exhibited by the most commonly collected E. coccinea, the species with most collections assessed in the present paper. Assessments of conservation status were carried out following IUCN (2000), based on current knowledge and using their terminology on categories, criteria and subcriteria.

Distribution: W Java and Borneo. Conservation status: EN B1ab (iii). Deforestation seriously threatens the forest in the southern part of Java, including its type locality at Cipatuja. With only one recent collection from one location, despite intensive searching, it is potentially endangered in Java. Valeton noted as early as 1921(b), that this species is apparently very rare as are the primaeval forests, its habitat. Additional material examined: Banten Province, buffer zone of Ujung Kulon NP, Gunung Honje, 250 m, 17 Nov 1996, flowering and fruiting, Funakoshi IU 19 (E, BO n.v.). Notes: The collection by Funakoshi is to my knowledge the only one from Java since the type of E. parva was collected in 1913, and the first including the infructescence. The material matches the type of E. brachychila from

5 Etlingera Giseke of Java 149 Sarawak very well, except the calyx and corolla tube being slightly longer and the lateral lobe of the labellum being yellow but these characters are still within the range of E. brachychila var. vinosa A.D. Poulsen also from Borneo. Etlingera brachychila is easily distinguished from other Javanese species with their inflorescence at ground level by its poorly developed involucral bracts, short labellum and its conspicuous soft-toothed fruit somewhat resembling an Amomum. It resembles two species so far only known from Borneo: E. aurantia A.D. Poulsen and E. kenyalang A.D. Poulsen & H. Chr. Etlingera brachychila is distinguished from the other two by the smaller and fewer sterile bracts which give less support to the spike. The apex of the calyx is less mucronate. Finally, E. brachychila differs in its flower colour and the orientation of the lateral lobes of the labellum (reflexed vs. erect or involute). In Borneo a variety E. brachychila var. vinosa has a white-waxy sheath and often more or less bullate leaves which are burgundy beneath. In Java, this variation in leaf colour has not been documented and the leaves are only sparsely hairy. Future collections may demonstrate more pubescent leaves like those E. brachychila var. brachychila in Borneo. 2. Etlingera coccinea (Blume) S. Sakai & Nagam. Edinburgh J.

Seeds 2 3 mm across. Plate 1B. Local names and uses: Blume (1827) listed tepus, tepus gede, and mancirian (Sundanese). Valeton (1904) mentioned that tepus bener (genuine) and tepus leuweung (forest or wood) as names for subspecies with an entire or emarginate apex to the labellum, respectively. Heyne (1927) also mentioned tepus bener but specified that mancirian is the name of the flower, and rongod refers to the fruit. The young leafy shoot and the fruits are edible (Poulsen et al. 2282). Shoot tastes cabbage-like when young; bitter when old. Even though it is often considered useful I never came across it being planted and cultivated in Java. Etymology: Coccinea means scarlet. Ecology and habitat: Old field edges, in traditional home gardens (but not planted), secondary forests, or in gaps or near streams of primary forests at m. Valeton (1904) noted that the seeds are frequently dispersed by animals that leave behind a big hole in the top of the empty fruit. In Sumatra and Borneo, E. coccinea is pollinated by bees or spiderhunters (Kato et al., 1993; Sakai et al., 1999). Fruit eaten by rodents. Distribution: Thailand, Peninsular Malaysia, Singapore, Sumatra, Java and Borneo. Conservation status: LC (least concern), because of its wide distribution and persistence in very disturbed habitats.

Singapore 59 (1&2) 2007 Additional material examined: Banten Province: bufferzone of Ujung Kulon NP, Gunung Cibiug, 3 km E of Tamanraya village (6 o 47 S 105 o 32 E), 130 m, 27 Apr 2005, flowering and fruiting, Poulsen et al (AAU, BO, E). West Java Province: Gunung Salak (6 o 40 S 106 o 44 E), 950 m, 28 Sep 2003, flowering, Poulsen et al (BO); Halimun NP, Citalahab (6 o 44 S 106 o 32 E), 1100 m, 20 Mar 2004, flowering and fruiting, Poulsen et al (AAU, BO, E); Gunung Kancana, 2 km WSW of Parabuan village (6 o 55 S 107 o 03 E), 950 m, 27 Mar 2004, flowering, Poulsen et al (AAU, BO); Cisarakan (7 o 05 S 106 o 35 E), 500 m, 10 Aug 2006, flowering, Poulsen et al (BO); Cikaso (7 o 22 S 106 o 37 E), 40 m, 11 Aug 2006, flowering, Poulsen et al (BO, E); Gunung Cikuray (7 o 19 S 107 o 54 E), 1250 m, 13 Aug 2006, flowering, Poulsen et al (BO, E). Notes: In Java, E. coccinea can most easily be confused with E. megalocheilos. Etlingera coccinea differs in its (most often) sessile leaves, absence of tufts on the apex of the calyx, the broad, pink dorsal corolla lobe hooded over the stamen, the long-elongate labellum with a broad yellow centre and red margin and thecae dehiscing almost to base. The margins are inrolled and like a tube so that the red at first glance appears to be in the centre of the labellum (like in E. megalocheilos). Most often the leaf of E. coccinea is glabrous but not always. During my recent survey, one plant was collected in which the lamina was pubescent beneath (Poulsen et al. 2457) and E. megalocheilos also varies regarding the indumentum beneath the lamina. Thus as demonstrated in the Bornean revision of Etlingera (Poulsen, 2006) indumentum is not a completely reliable character. Schumann (1904) regarded E. coccinea as a synonym of E. punicea, and therefore the latter name was used by Smith (1986) and others. This misconception was finally sorted out by Sakai & Nagamasu (2003). Valeton (1904) described beautifully how the flowers in one inflorescence opened, in up to three circles of up to 15 flowers, each lasting only one day; he obviously took great care in making precise observations of live plants of Etlingera in Java. Valeton (1904) further mentioned that the subspecies (cf. etymology above) with an entire apex to the labellum is much more common than the emarginate one, whereas I found the opposite to be the case. In any case, I do not see any reason to formally recognize this variation in two subspecies. The local name in Java, tepus (Sundanese), is also used in Borneo by many tribes (Poulsen, 2006). Often peoples in Borneo use a generic name for all gingers that seems to be derived from that. The giant form that I collected in several places in Borneo is most similar to wild plants in Java,

9 Etlingera Giseke of Java 153 such as those on Gunung Salak. All these lack a strong smell. Many local names in Borneo include an epithet that refers to the distinct smell. Some forms may have been selected over centuries and taken into cultivation. These plants are often smaller, but I did not find any floral measurements justifying the recognition of the smaller and smellier plants even at a lower taxonomic rank. In this context it is interesting that the enigmatic Etlingera walang (Blume) R.M. Sm. is considered a very smelly plant. New collections in Java of a smelly Etlingera coccinea may provide the necessary evidence for establishing this synonymy. 3. Etlingera elatior (Jack) R.M. Sm. Notes Roy. Bot. Gard.

Seeds to 4 mm across, rounded-angular. Plate 1C. Local names and uses: Blume (1827) listed the following names konje, hunje, hunje-reuma (Sundanese). Heyne (1927) mentioned that rombe refers to the young inflorescene and combrang (tjombrang orth. var.) to the flowers (also Sundanese) and in Javanese or kecombrang, cumbrang, combrang. Hondje hedjo (Sundanese; hedjo means green referring to the colour of the leaves as opposed to E. hemisphaerica that has reddish leaves beneath; Poulsen et al. 2293). Edible leafy shoots, flowers, and fruits. Often sold at the market. Etymology: The epithet refers to the raised inflorescence. Ecology and habitat: It is difficult to say with certainty if Etlingera elatior is native to Java as it has been cultivated there for a very long time. Bakhuizen f. (1968) listed its occurence in primary and secondary forests to 1200 m, though I am yet to encounter it in natural vegetation in Java. Distribution: Widespread in the tropics (Poulsen, 2006). Conservation status: LC (Least Concern). Not threatened.

12 156 Gard. Bull. Singapore 59 (1&2) 2007 Additional material examined: West Java Province, Gunung Kancana, 800 m, W of Parabuan village (6 o 54 S 107 o 03 E), 800 m, 26 Mar 2004, flowering, Poulsen et al (AAU, BO). Notes: Etlingera elatior is most similar to E. hemisphaerica but the most striking differences between the two is the the longer and reflexed lower bracts in the involucre of E. elatior. Furthermore, the inflorescence is usually more than 1 m (vs. <1 m), the receptacle extends to 10 cm (vs. <2 cm), and the fruit is reddish (not green). The description by Bakhuizen f. (1968) mentions that the leaves can be purple beneath which could resemble those of E. hemisphaerica. This I have only observed in Java in cultivated plants. The colour of the bracts of E. elatior can vary from deep blood-red to white (Poulsen, 2006). In Java, some of the inflorescences sold in the market are deep red whereas the more typical ones are pink. In rare cases, such as the type of Diracodes javanica Blume, the inflorescence in E. elatior appears terminally on a leafy shoot. 4. Etlingera foetens (Blume) R.M. Sm. Etlingera foetens (Blume) R.M.

14 158 Gard. Bull. Singapore 59 (1&2) 2007 Javan Skunk Marten (possibly Mydaeus javanensis) which is infamous for its revolting smell, resembling asafoetida and fennel. The fruits are eaten. Etymology: The epithet means smelly. Ecology and habitat: Lowland primary or disturbed forests at banks of rivers or streams to 950 m. Distribution: Borneo, Java, Sumatra and possibly Peninsular Malaysia and Thailand. Conservation status: EN B1ab(iii). Deforestation seriously threatens the forest in Java especially in the lowlands. Already Bakhuizen f. (1968) noted that E. foetens was rare and, during my surveys from , I only found one sterile plant. Additional material examined: West Java Province, Gunung Kancana, 2 km WSW of Parabuan village (6 o 55 S 107 o 03 E), 950 m, 27 Mar 2004, sterile, Poulsen et al (AAU, BO). Notes: Etlingera foetens is easily recognized by its deeply reticulate and broad leaf bases, plain red flowers where the dorsal lobe of the corolla does not cover the anther, the elongate and broad labellum and the strong smell when crushed. I have not seen flowering plants of E. foetens in Java and thus the description of floral characters are based on Bornean measurements, which, however, match nicely those in the Flora of Java (Bakhuizen f., 1968). In Borneo, all flowers observed so far are uniformly red whereas in Sumatra the lateral margins of the labellum are occasionally slightly yellow. Thus it would not be surprising if flowers in Java showed similar variation. As discussed in detail by Poulsen (2006), E. triorgyalis (Baker) R.M. Sm. is similar to E. foetens. It is sometimes a taller plant (8 m vs. 5 m) and has larger sterile bracts (with recurved apices making the inflorescence cyathiform), and a greater number of flowers per inflorescence. In addition, several floral measurements (calyx, corolla, and width of apical lobe of the labellum) are larger (Khaw, 2001). These characters seem to separate the material from Peninsular Malaysia (including the type of E. triorgyalis from Perak) from that of Java, Borneo and Sumatra. 5.

Hunje leuweung (Sundanese; Blume, 1827 according to Valeton (1904) leuweung means wood; he considered E. hemisphaerica the wild origin of E. elatior). Heyne (1927) added the names hondje hedjo and hondje laka (based on what he called Nicolaia atropurpurea); these local names are also given for E. elatior and E. solaris, respectively. Leafy shoot and fruit edible. According to Bakhuizen f. (1968), cultivated locally. Etymology: The epithet means hemispherical, probably referring to the cupshaped inflorescence. Ecology and habitat: Primary and secondary lowland forests to 950 m. Fruits emptied by rodents. Distribution: Sumatra, Java, and probably Peninsular Malaysia and Thailand. There are no definite records of this species from the wild in Borneo but it is cultivated at Tenom Agricultural Park in Sabah. A. Lamb (pers. comm.)

17 Etlingera Giseke of Java 161 found it near Tenon and believes it was introduced by Javanese workers who came to work in the tobacco estates at about 1850 and took useful plants with them from Java. Conservation status: VU B1ab(iii). Vulnerable by extent of occurrence estimated <20,000 km 2, known from <10 locations, and decline in the extent and quality of lowland forest habitats in Java. Additional materials examined: Banten Province: buffer zone of Ujong Kulon NP, Cikacang (6 o 48 S 105 o 32 E), 130 m, 28 Apr 2005, fruiting, Poulsen et al (BO, E). West Java Province: Gunung Kancana, 2 km WSW of Parabuan village (6 o 55 S 107 o 03 E), 950 m, 27 Mar 2004, sterile, Poulsen et al (AAU, BO); Gunung Tutupan, (7 o 22 S 106 o 42 E), 150 m, 11 Aug 2006, flowering and fruiting, Poulsen et al (AAU, BO, E, L). Notes: Amongst the Etlingera presently known in Java, E. hemisphaerica is most similar to E. elatior from which it differs in its erect bracts (not reflexed) and in having a lamina that is reddish beneath. Floral differences between the two species seem to be minor except for the anther possibly being longer in E. hemisphaerica, but more material is needed to test this. With its leaves being wine-red beneath, Etlingera pyramidosphaera in Borneo appears very similar to E. hemisphaerica but the former differs in having a narrower inflorescence with fewer flowers, the anther thecae dehiscing for their entire length, and in its beaked fruits. Bakhuizen f. (1968) described the fruits as globular or spindle-shaped, beaked. In the revision of Etlingera of Borneo, Poulsen (2006) emphasized the fruit shape as a reliable character. Thus, in the present account above, the fruit is described as globular not beaked! More material will be necessary to establish if beaked fruits of hemisphaerica-like plants actually occur in Java, and if these plants deserve taxonomic recognition. 6.

The smell is variable; at least in Borneo (Poulsen, 2006) and in Sumatra the smell is strong and somewhat unpleasant, similar to E. foetens. According to Heyne (1927), E. megalocheilos was not cultivated but the fruits searched for in the wild and eaten. Etymology: The epithet refers to the large labellum. Ecology and habitat: Often dominant in forest gaps or completely open areas to 1300 m. Distribution: Malay Peninsula, Singapore, Sumatra, Java, and Borneo. Conservation status: Least concern (LC). Bakhuizen f. (1968) thought it scarce everywhere, but I have observed it in several very open habitats and consider it rather resilient to disturbance. It may actually have expanded in recent years.

20 164 Gard. Bull. Singapore 59 (1&2) 2007 Notes: Etlingera megalocheilos is most easily confused with E. coccinea that also has the inflorescence embedded in the soil and an elongate, red and yellow labellum. But in E. megalocheilos the anther is not covered by the corolla lobe, the margins of the labellum are not inrolled, and the labellum is red with more or less pale red or yellowish lateral lobe margins (not yellow with red margins). Griffith (1851) described Achasma megalocheilos from Peninsular Malaysia a taxon also mentioned by Ridley (1899), Holttum (1950), and which Khaw (2001) called E. littoralis following Burtt and Smith (1986). I have not encountered fruits of E. megalocheilos in Java but those I have seen from Borneo (Poulsen, 2006) and Sumatra and also described by Holttum (1950) match Valeton s (1906) description and illustrations of the fruits of A. megalocheilos which are rounded and smooth but with a few warty protuberances near the top, based on material from Malabar Mts., Java. 7.

Etymology: The epithet means sun-like probably referring to the inflorescence at anthesis. In the Mountain Flora of Java, van Steenis (1972) mentions E. solaris as earth sun. Ecology and habitat: Montane forests near streams at m.

22 166 Gard. Bull. Singapore 59 (1&2) 2007 Distribution: Sumatra, W Java as far east as Gunung Merapi in Central Java. Conservation status: VU B1ab(iii). Vulnerable by extent of occurrence estimated <20,000 km 2 of montane forest, known from <10 locations, and decline in extent and quality of habitat. Additional materials examined: West Java Province: Halimun NP, Citalahab (6 o 44 S 106 o 31 E), 1100 m, 21 Mar 2004, flowering and fruiting, Poulsen et al (AAU, BO, E, L); Gede-Pangrango NP, Cibodas (6 o 45 S 107 o 59 E), 1750 m, 28 Mar 2004, flowering and fruiting, Poulsen et al (AAU, BO). Notes: The peduncle of Etlingera solaris is variable in position and direction but the species is easily recognized by the long and deeply bilobed ligule and the horn-shaped, twisted, pubescent bracts. Valeton (1921a, p. 137, plate 6) described E. solaris var. aurantiaca from Gunung Salak, Java. The variety is supposed to have an erect inflorescence to 20 cm (not procumbent), shorter teeth to the calyx and the lip orange rather than dark red, and possibly the same as Elettaria pallida Blume. I have seen this at Halimun and agree with Bakhuizen f. (1968) that it is hardly different. A collection (Poulsen 2418) from Gunung Kerinci, Sumatra, had its inflorescence embedded in the ground as the peduncle was subterranean, the stamen was shorter (13 14 mm) but the anther dehiscence matched that in the Javanese material. Amomum chrysocalyx K. Schum. was listed as a synonym by Bakhuizen f. (1968) but, after inspecting its type, I am convinced that it has has no relevance to E. solaris. Incompletely Known Species 8.

23 Etlingera Giseke of Java 167 obovate, glabrous throughout; length to width ratio 4 6; base acute; apex shortly caudate-acuminate; margin glabrous. Inflorescence fusiform, red: receptacle discoid, with <20 flowers (estimated from Valeton, 1921a, Plate 3), ca 4 open at a time. Peduncle short, curved, scales obovate, glabrous, red, apex rounded, mucronate. Spike ± ovoid, only including bracts: to 5.5 x cm. Sterile bracts x 3 cm, oblong. Fertile bracts to x cm. Bracteole c. 4 cm, glabrous. Flower: calyx 5 cm, glabrous, 3-toothed. Corolla lobes 25 x 5 mm, linear. Labellum 3 x 1.5 cm long, with about equal elliptic upper and lower halves separated by a distinct constriction, red with yellow margin; central lobe ca 10 mm wide, margin slightly curled. Filament 7 mm; anther ca 10 mm, crest bilobed, divergent. Style glabrous. Stigma discoid, ostiole transverse; ovary pubescent. Epigynous glands 4 mm. Infructescence unknown. Local names and uses: Hondje (Heyne, 1927). Valeton (1921a) noted that the entire plant is strongly aromatic like Nicolaia speciosa (E. elatior). Etymology: The epithet is in honour of the Dutch botanist Karel Heyne ( ) who collected in Java and Sumatra. Ecology and habitat: Unknown. Seems to tolerate growing in a rather open habitat. Distribution: Java. Conservation status: Unknown. Notes: The illustration of Etlingera heyniana in Valeton (1921a, Plate 3) looks to me more like an inflorescence of E. megalocheilos where the flowers have not fully opened yet, similar to what may be observed in E. nasuta (K. Schum.) R.M. Sm. in Borneo. Apart for the labellum being erect and significantly shorter in E. heyniana, there are not stron evidence to separate them. At least the colours of the labellum (red with yellow margin) are the same. The type at BO mentions Gunung Honje as the locality not Sentiong. I thus went to one G. Honje, of which locality there might actually be several in Java. At the locality I visited near Ujung Kulon, E. megalocheilos was very common. A closer study of the floral development of this species may be fruitful. Even though Valeton (1921a) mention the distinct smell of E. heyniana, this is not strong evidence against the possibility of synonymy with E. megalocheilos, as in Sumatra I have experienced that it may sometimes

24 168 Gard. Bull. Singapore 59 (1&2) 2007 have a strong smell. 9. Etlingera walang (Blume) R.M. Sm. Etlingera walang (Blume) R.M. Sm., Notes Roy. Bot. Gard.

No recent material has been seen and the description below is only a summary of what is presented by Valeton (1904; 1906) and Bakhuizen f. (1968). Rhizome slender. Leafy shoot m. Sheath glabrous. Ligule c. 10 mm, finely ciliate, otherwise glabrous, stout. Petiole 5 10 mm. Lamina x cm, narrowly obovate, glabrous throughout; average length to width ratio 6 7.5; base ± unequal, narrowly cuneate; apex shortly acuminate, finely hairy; margin glabrous. Inflorescence: receptacle almost flat, with <20 flowers, c. 3 open at a time. Peduncle to 8 cm, subterranean, scales to 5 x 1.3 cm, mucronate, finely longitudinally veined. Spike ovoid-cylindrical, only including bracts: to 7 x cm; about 5 sterile bracts, narrowly obovate, acuminate, mucronate: to 6 8 x 1.3 cm. Fertile bracts to 6 cm, narrower than sterile bracts. Bracteole c. 5 cm, bifid, densely pubescent at least in lower half. Flower: calyx as long as corolla, irregularly 3-toothed. Corolla red; lobes erect, oblong, dorsal lobe longest. Labellum yellow with red margin; lateral lobes, margin curved upwards and conspicuously crenate, central lobe 5 cm long, narrow, ligulate-spathulate, deeply bilobed. Filament 7 mm; anther ca 10 mm, crest bilobed, divergent. Style 5.5 cm, hairy below apex. Stigma triangular, hairy; ovary pubescent. Epigynous glands 4 mm. Infructescence unknown. Local names and uses: Walang (Sundanese). Leaves are served as a side dish with rice (Valeton, 1904), as a condiment, or the leaves are burnt on rice fields as an insect repellent (Heyne, 1927).

25 Etlingera Giseke of Java 169 Etymology: The epithet refers to the bad-smelling rice bug, walang sangit (Leptocorisa acuta Thunb. or L. varicornis Fabr.). Bakhuizen f. (1968) noted that all parts especially the leaves are ill-smelling. Ecology and habitat: forests to 1200 m, and cultivated. Distribution: Java. Conservation status: Impossible to assess. Notes: In Blume s protologue (1827) of Etlingera walang he placed a question mark after the genus (Donacodes). All that is reported of the new species is that the leaves are elongate-linear-lanceolate, acuminate, and glabrous, and it appears he had not seen the flowers. I think the question mark refers to the uncertainty of which genus to place it in, but, without the flowers, one has to wonder why Blume placed it in Donacodes (the remaining species of which are presently placed in Hornstedtia). Valeton (1904) did detailed studies around Bogor where he found that E. walang was one of the most economically important Sundanese plants and often cultivated, of unknown origin and very easily recognized by its characteristic smell that stays for months with the specimen after drying. He studied the inflorescence in detail (see plate in Valeton, 1906) and thought it was much more narrow than that of E. coccinea and E. foetens but that these three species formed a natural group and apart from the crenate margin to the labellum, E. walang was very similar to E. coccinea. In my opinion what Valeton illustrated is just an E. coccinea with a deeply bifid apex to the labellum, similar to Poulsen et al from Ujung Kulon. It is important to remember, however, that the basis for Valeton s descriptions (1904; 1906) and illustrations (1906; Plate 162, figs. 1 9) are not based on the type. The issue of smell is, however, very interesting. As mentioned in the notes above on E. coccinea, in Borneo a very smelly form of this species also of unknown origin is often cultivated and commonly sold in the markets. More detailed surveys around Bogor may result in the discovery of walang and it would then be possible to establish if this just a form of E. coccinea. Conservation of Etlingera in Java None of the seven well-known species of Etlingera is endemic to Java. They all display geographical affinity with nearby Borneo or Sumatra to the north and west, but no overlap with species in Wallacea to the east.
