Abstract:
A review of the white-flowered Amorphophallus species in Sarawak is presented. A total of five species are recognized, four of which belong to the Eburneus Group and are restricted to limestone, and moreover, locally endemic: A. eburneus Bogner (Padawan and Tebedu areas), A. brachyphyllus Hett. (Bau), A. juliae sp. nov. (Merirai) and A. niahensis sp. nov. (Niah). A fifth species, Amorphophallus infundibuliformis Hett., A.Dearden & A.Vogel, of doubtful affinity, is widespread and locally abundant on a variety of substrates excluding limestone. A key to the white-flowered species in Sarawak is presented and all species are illustrated.

 

Abstract:
Fieldwork targeting indigenous Homalomena at Nanga Sumpa, part of the Batang Ai drainage system (Sri Aman Divison, Sarawak) revealed 14 species of which six are novel and herewith described: Homalomena atrox P.C.Boyce, S.Y.Wong & Fasihuddin, H. clandestina P.C.Boyce, S.Y.Wong & Fasihuddin, H. hanneae P.C.Boyce, S.Y.Wong & Fasihuddin, H. sengkenyang P.C.Boyce, S.Y.Wong & Fasihuddin, H. symplocarpiifolia P.C.Boyce, S.Y.Wong & Fasihuddin, and H. vivens P.C.Boyce, S.Y.Wong & Fasihuddin. Of the six Homalomena species present at Batang Ai for which there are pre-existing names, two, H. borneensis Ridl. & H. humilis (Jack) Hook.f., are species complexes still awaiting a full taxonomic and systematic investigation, and are treated here as morpho-taxa to which we apply the earliest applicable epithet. The remaining four species with available names have only recently been described: H. geniculata M.Hotta (1967); H. vagans P.C.Boyce (1994), and H. josefii P.C.Boyce & S.Y.Wong, and H. pseudogeniculata P.C.Boyce & S.Y.Wong (2008). Additionally, two further species located during fieldwork, that while unarguably novel based on their vegetative morphology, were not located as fertile plants and have yet to flower in cultivation; they are here treated as sp. nov. A & B. Of the 14 species present at Batang Ai, five have significance in the ethnobotany of the indigenous Iban people of the Ai drainage, and of these five, four are novel. A key to the Homalomena in the Batang Ai drainage area is given, and all species are illustrated.

 

Abstract:
In a botanical expedition to Christmas Island in 1904, Sir Henry Ridley*, the first director of the Singapore Botanic Gardens, discovered and thereafter described an endemic ground orchid, Zeuxine exilis Ridl. Botanical expeditions and surveys over the century since the original discovery failed to relocate Z. exilis. We report here the rediscovery of Z. exilis in rainforest in the western section of the island, and in Ridley’s honour, propose “Ridley’s jewel orchid” as its common name. The distribution and conservation status of Z. exilis remains to be determined. Despite a century of ecological insults to this unique oceanic island, primarily through phosphate mining and the introduction of invasive species, the rediscovery of this endemic orchid renews hope that the imperiled biodiversity on this island is resilient and can be conserved.

Abstract:
Based on Landsat TM/ETM images from 1988, 2003 and field data of 2006, land uses and land cover changes were researched over 18 years in the dipterocarp rain forest area in Southern Yunnan of China. The expansion of rubber plantations has resulted in a dramatic decrease in natural forest cover, especially the tropical seasonal rain forest at lower elevation. In 1988, rubber plantations covered 765.06 ha which increased to 2,294.07 ha in 2003, with an annual rate of change at 13.32%. The pace of change increased after 2003, with a change of 213.69 ha per annum. The tropical seasonal rain forest has decreased by 111.35 ha per annum since 1988 in the study area. Arable lands increased during 1988 and 2003 but declined rapidly from 2003 to 2006 due to expansion of rubber plantations and the construction of reservoirs. There was an increase in water bodies from 2003 to 2006 as well as construction areas. Market prices, policies, increasing population, and the unregulated pursuit of commerce and trade, at times at the cost of the environment were the main driving forces of change. We suggest that local government takes strong action to regulate further expansion of rubber plantations and creates conditions for sustainable and harmonious development of economy, society and natural resources in biodiversity rich region of Southern Yunnan.

Abstract:
Rhaphidophora latevaginata M.Hotta, a neotenic, shingling, climbing aroid, hitherto considered a Bornean endemic, has recently been found and collected from the southern part of the east coast of Peninsular Malaysia (Johor: Kota Tinggi and Mersing), where so far it appears to be restricted to kerapah and the drier (raised podzol) facies of seasonally inundated peatswamp forest. This discovery of R. latevaginata takes to 18 the number of Rhaphidophora known to occur in Peninsular Malaysia, of which three are endemic. An updated description of R. latevaginata, a key to the Rhaphidophora species of Peninsular Malaysia, and a plate illustrating the diagnostic characters of those with shingle-stage juveniles is presented. A brief note on the significance of the new record with regard the Riau Pocket is made.   

Abstract:
Scindapsus lucens Bogner & P.C.Boyce is a species of considerable horticultural potential, arguably rivalling the commercially important S. pictus, originally described from cultivated material of unknown provenance and only later found wild in Sumatera. It has recently been discovered and collected from several localities in southern Peninsular Malaysia, representing both a new record for Malaysia, and through clonal propagation via various tissue culture techniques would supply a sustainable potential source of a local commercial ornamental horticultural product. An enlarged description of S. lucens, and a key to the Peninsular Malaysian Scindapsus are offered. A plate illustrating the diagnostic characters of S. lucens is given.

Abstract:
A new species of Begonia (Begoniaceae), B. droopiae Ardi, is described from the Indonesian island of Sumatra. It belongs to Begonia sect. Reichenheimia and is a limestone endemic in the Sawah Lunto District. Its IUCN threatened category is considered to be ‘Vulnerable’.

Abstract:
Endiandra trees are not frequently encountered in the forest in Indonesia. Recent exploration in Waigeo Island resulted in the collection of three species of Endiandra.

Abstract:
The subfamily Ptychanthoideae of the family Lejeuneaceae (Hepaticae) in West Java is still poorly known. A study of Ptychanthoideae in this area reveals the occurrence of 26 species, in 8 genera: Acrolejeunea (Spruce) Schiffn. (3 species), Archilejeunea (Spruce) Schiffn. (1 species),
Lopholejeunea (Spruce) Schiffn. (10 species), Mastigolejeunea (Spruce) Schiffn. (3 species), Ptychanthus Nees (1 species), Schiffneriolejeunea Verd. (2 species), Spruceanthus Verd. (2 species) and Thysananthus Lindenb. (4 species). Mastigolejeunea indica and Thysananthus minor are newly
reported for Java. The altitudinal and geographical ranges of the species of Ptychanthoideae from West Java are presented as well as a key to the species and an assessment of their phytogeography. It appears that the species are rather widespread; none of the species are endemic to Java or
western Malesia. The widespread distribution of the species is probably due to their dispersal by spores, which may be easily carried by the wind over long distances, and by the rather old geological age of the group.

Abstract:
New combinations are made for the seven species of Dalrympelea (Staphyleaceae) from Malaysia that were previously included in Turpinia. Dalrympelea pomifera Roxb. is distinct from D. sphaerocarpa (Hassk.) A.T.Nor-Ezzawanis and does not occur in Malaysia and Turpinia ovalifolia Elmer from the Philippines is distinct from D. trifoliata (Ridl.) A.T.Nor-Ezzawanis.

Abstract:
A new species, Cheilocostus borneensis, is described. Specimens were collected in Sarawak in 1987 and Kalimantan in 2000, but only intensified surveys of gingers in Sarawak in 2002-2004 provided sufficient collections to recognize the new species, which is here described and illustrated. It is closely related to the widespread C. globosus from which it differs by the chocolate-brown sheaths, absence of axillary shoots on vegetative stems, larger leathery leaves, and by its calyx that is not prickly.

Abstract:
Three new species of Begonia (Begoniaceae) are described from Nepal. All three species (Begonia nuwakotensis S. Rajbhandary, Begonia panchtharensis S. Rajbhandary and Begonia taligera S. Rajbhandary) belong to Begonia section Platycentrum, and they increase the number of Begonia species known from Nepal to 22. All are considered to belong to the IUCN threat category VUD2.

Abstract:
Genetic variation within and between populations of Scutellaria slametensis Sudarmono & B.J.Conn and S. discolor Colebr. on Gunung Slamet (Jawa Tengah, Indonesia) are evaluated by allozyme electrophoresis. Gels stained by 4 enzyme systems, namely, Aspartate aminotransferase (Aat), Esterase (Est), Malate dehydrogenase (Mdh) and Peroxidase (Per), were used to evaluate the number of polymorphic loci. The mean of total number of observed alleles per locus (A), mean of total number of effective alleles per locus (Ae), percentage of polymorphic loci (Pp%), and expected genetic heterozygosity (He) have been generated as parameters of genetic variation. The interpopulation genetic differentiation (FST) and estimated geographic distance between populations were used to evaluate the correlation between genetic differentiation and geographic effect. It was found that S. slametensis is genetically distinct from S. discolor (D = 1.4572). The mean genetic variation of S. slametensis (Pp = 75 %, A = 2.00, HE = 0.450) is greater than that of S. discolor (Pp = 25 %, A = 1.25, HE = 0.125). Almost all loci of the latter species are monomorphic and homozygotic, especially population 9 near Baturaden (Pp = 0%; HE = 0; Allele frequencies all = 1). There is a moderately high degree of variation between populations of these two species (FST = 0.585, SE ± 0.092), whereas within-population variation is low (1–FST = 0.415). Both species are out-breeding (at subpopulation level: FIS
= -0.973, SE ± 0.015; and population level: FIT = 0.180, SE ± 0.183), with low levels of gene flow within and between populations (Nm = 0.249, SE ± 0.065). The chromosome number of S. slametensis and S. discolor is 2n = 24.

Polyalthia lasioclada I.M. Turner, sp. nov. is described. It is a small tree known from the Mount Kinabalu area of Sabah.

Abstract:
A revision of the Schismatoglottis nervosa Ridl. species complex is presented. Ten species are recognized, of which three species are pre-existing (S. nervosa, S. elegans A.Hay, and S. brevicuspis Hook.f.) and seven are novel and described here (Schismatoglottis adoceta S.Y. Wong, S. linae S.Y. Wong, S. matangensis S.Y.Wong, S. simonii S.Y.Wong, S. tessellata S.Y. Wong, S. turbata S.Y. Wong, and S. ulusarikeiensis S.Y. Wong.) The S. nervosa species complex is readily delimitated by the pungent terpenoid smell when the vegetative tissues are crushed, and by the presence of longitudinally ridged petioles. A key to the S. nervosa species complex is presented and all species are illustrated.

Abstract:
A new Philippine species of Rafflesia from the Sierra Madre Mountain Range of northeastern Luzon is described. Rafflesia aurantia is the ninth presumed endemic species thus far described from the Philippines, and the fifth reported from the island of Luzon. This species is apparently allied to R. tengku-adlinii of Sabah - both are small-sized and their overall color is similar. Biogeographical considerations and the morphological differences between our new species and R. tengku–adlinii, however, strongly support the recognition of two distinct evolutionary lineages/species. The conservation status of the fast disappearing lowland dipterocarp forests in northeastern Luzon, particularly the type locality in the Quirino Protected Landscape (QPL) is also discussed and suggests that the new species may be highly threatened.

Abstract:
Seven new Begonia species are described from northern and western Sumatra: Begonia gracilicyma Irmsch. ex M.Hughes (unplaced to section), Begonia laruei M.Hughes (sect.

Geodorum citrinum Jacks. is a new record for the orchid flora of Vietnam.

Abstract:
A new moss species collected from Peninsular Malaysia, Fissidens benitotanii Z.Iwats., K.-T.Yong & Tad.Suzuki is described. The species belongs to subgenus Fissidens section Fissidens. Most of the members in sect. Fissidens have smooth laminal cells, except for a few species, which included this newly described species, possess unipapillose laminal cells. Fissidens benitotanii is easily distinguished from other Fissidens species in the region by the following characteristics: narrowly lanceolate leaves with shortly excurrent costa, thin limbidia that disappear near leaf apex, and unipapillose laminal cells with distinctive sharp papilla.

Abstract:

This is here described and illustrated and included in additions to the key to Bornean Schismatoglottis published by Hay & Yuzammi (2000).

Abstract:
A taxonomic account of the palm genus Livistona is presented. Thirtysix species are recognised. Taxonomic and nomenclatural changes are applied to a number of species. Livistona rotundifolia (Lam.) Mart. is treated as a highly variable species, with L. rotundifolia var. luzonensis Becc., L. rotundifolia var. microcarpa (Becc.) Becc., L. rotundifolia var. mindorensis (Becc.) Becc. and L. robinsoniana Becc. placed as synonyms; L. fengkaiensis X.W.Wei & M.Y. Xiao is placed under L. speciosa Kurz; Livistona chinensis var. subglobosa (Hassk.) Becc. is placed under L. chinensis (Jacq.) R.Br. ex Mart.; Livistona tonkinensis Magalon is placed under L. saribus (Lour.) Merr. ex A.Chev.; and Livistona kimberleyana A.N.Rodd is placed under L. lorophylla Becc. A neotype is proposed for L. saribus, and lectotypes are chosen for L. altissima Zoll., L. beccariana Burret, L. hoogendorpii Hort. ex Teysm. & Binn. ex Miq., L. olivaeformis (Hassk.) Mart., L. subglobosa (Hassk.) Mart., L. tonkinensis Magalon, L. woodfordii Ridl., and Chamaerops biroo Siebold.

Abstract:
The Asian species of Lepidopilum (Brid.) Brid. are reviewed. Hitherto, L. novae-guineae E.B. Bartram is the only remaining Asian species in the predominantly neotropical genus. However, examination of the type specimen of this taxon proves it to be a synonym of Dimorphocladon borneense Dixon.

Abstract:
Seven new species are described from Sarawak, Borneo: two, Begonia payung S.Julia & Kiew and B. sarangica Kiew & S.Julia, are endemic to Bukit Sarang in Ulu Sungai Kakus, Tatau District; and five, B. juliasangii Kiew, B. meriraiensis S.Julia & Kiew, B. nagaensis Kiew & S.Julia, B. piring Kiew & S.Julia and B. rhodochaeta S.Julia & Kiew, are endemic in the Ulu Merirai area in the Tatau District.

Abstract:
While revising the genus Habenaria Willd. for the Flora of Thailand the first author of this paper came across herbarium material of an unusual terrestrial orchid from Khao Yai National Park in central Thailand with small Liliaceae-like flowers. A subsequent search revealed that the same plant had been noted by Kerr (1969) in Laos and was later illustrated by Seidenfaden (1992: 70). A third collection, also in central Thailand, was made by the second and third authors of this paper. As the plant does not match any currently known species it is here described as new. 

Abstract:
A new combination of Etlingera fenzlii (Kurz) Škorničk. & M. Sabu (Zingiberaceae) based on the basionym, Amomum fenzlii Kurz, is proposed. Recent exploration on Great Nicobar Island resulted in the collection of this endemic species. An amended description with a colour plate is provided and a lectotype is designated.

Abstract:
This paper gives an overview of the genus Eugenia, with an emphasis on species found in the Philippines. In particular, the generic segregate Jossinia, adopted by Merrill for those species, is re-evaluated in the light of more recent research. This research does not support inclusion of species from the Asia-Pacific region in a segregate genus. Consequently, the Philippines species are here assigned to Eugenia and two new names, Eugenia uminganensis and E. inaequisepala, are proposed.

Book Review

Abstract:
Four new species of Homalomena (Araceae: Homalomeneae) are described from Sarawak. The current supraspecific taxonomy of the genus is reviewed and reasons for not recognizing at this time formal supraspecific units are justified although the need for species groupings is restated. In line with other large, taxonomically intractable groups, informal groups are proposed and circumscribed. All new species are illustrated.

Abstract:
Hapaline celatrix P.C.Boyce, a species known from only two collections and hitherto considered endemic to Brunei, has recently been collected in Gunung Mulu NP. An expanded description for the species, additional ecological notes and the first ever published field photographs are presented.

Abstract:
Four orchids, Appendicula floribunda (Schltr.) Schltr., Bulbophyllum elevatopunctatum J.J.Sm., Cymbidium sigmoideum J.J. Sm., and Dendrochilum bandaharaense J.J. Wood & J.B. Comber are new records for the Orchidaceae of Peninsular Malaysia.

Abstract:
A large number of Thai specimens belonging to the Peristylus tentaculatus complex were examined in the present study. No characters were found to distinguish between the three previously recognised species, Peristylus tentaculatus (Lindl.) J.J.Sm., P. tipuliferus (C.S.P.Parish & Rchb.f.) Mukerjee and P. garrettii (Rolfe ex Downie) J.J.Wood & Ormerod, which are therefore considered as conspecific.

Abstract:
The occurrence of Habenaria mandersii Collett & Hemsl. in Thailand is newly reported. The species was previously only known in Myanmar and the former French Indochina (Cambodia, Laos, Vietnam). It is very similar to H. hosseusii Schltr. and it is here suspected that it has frequently been mistaken for this species in the past. Short notes on the taxonomy of the H. hosseusii–mandersii–dentirostrata Tang & F.T.Wang group are also given.

Abstract:
Polyalthia saprosma I.M. Turner, sp. nov. (Annonaceae), is described from material hitherto confused with P. cinnamomea Hook.f. & Thomson. The new species is recorded from Sabah (Malaysia) and Kalimantan (Indonesia) on the island of Borneo.

Abstract:
Thirty two new species of Bulbophyllum, all from Sulawesi, are described.Names currently in use for various sections of Bulbophyllum are made junior synonyms to older sectional names that have been ignored so far, partly because their taxonomic content, as appears from the suite of species listed with the original descriptions of these sections, was ambiguous. These sectional names are lectotypified and re-instated.
