Two very distinctive new species of Homalomena Schott (Araceae-Homalomenaee are described from Sumatera (H. elegantula A. Hay & Herscovitch) and Borneo (H. expedita A. Hay & Herscovitch). Both are illustrated.

Abstract:
Morphological re-examination of Vaccinium dialypetalum sensu lato supports the view that it includes three distinct taxa: V. dialypetalum J.J.Sm., V micrantha (Ridl.) Vander Kloet and V. perakensis (Ridl.) Vander Kloet, all first described by Ridley under Agapetes but transferred by Sleumer to Vaccinium. Keys and descriptions are provided to distinguish the three taxa and new combinations are made for two taxa.

Abstract:
Limau purut {Citrus hystrix DC), cultivated throughout SE Asia, appears to be a selected form of the wild limau hantu (C. macroptera Montr., i.e. C. auraria Michel), though its earliest scientific name may be C fusca Lour. Complete synonymy with types is presented in a provisional arrangement of 'wild' plants and cultivars.  Suggestions for further work on C. hystrix and its relations with other cultivated citrus are made.  X Citroncirus is formally reduced to Citrus and a new name proposed for the citrange root-stock, Citrus x insitorum Mabb. A diagram of the relationships through hybridity of cultivated citrus is presented.

Abstract:
Leaf epidermal morphology of 5 species of Grewia L. and 32 species of Microcos L. (including) their type species) were examined. Grewia and Microcos both have glandular and nonglandular trichomes. Trichome characters alone cannot be used for delimiting Grewia from Microcos or for distinguishing species within each genus.  Five epidermal characters were useful for distinguishing the two genera in Peninsular Malaysia and Borneo. Grewia species differ from Microcos species in having radiating cuticular striation of epidermal / subsidiary cells, predominantly anomocytic stomata, stomata elliptic to broadly elliptic in outline with  mean length 18.6-22.9 um and average length-width (L/W) ratios of 1.2-1.4.  Microcos species were characterised by the absence of radiating cuticular striation of epidermal subsidiary cells (except in M. tomentosa), predominantly paracytic and anisocytic stomata, stomata broadly elliptic to oblate in outline with mean length 12-16.4 um and average L/W ratios of 0.9-1.1.

A dichotomous key to species is provided. All species are illustrated.

Abstract:
An alpha-taxonomic account of Rhaphidophora in New Guinea, Australia and the tropical western Pacific is presented as a precursor to the forthcoming Flora Malesiana Araceae treatment. Thirty species are recognised, of which 12 (R. cravenschoddeana, R. cryptantha, R. fortis, R. gorokensis, R. guamensis, R. intonsa, R. intrusa, R.jubata, R kokodensis, R mima, R. pilosa and R. waria) are novel. Twenty new synonomies are made: R. hollrungii and R. iboensis = R australasica; R. pallidivenia = R. conica; R. oreophila = R. discolor; R. wentii = R. geniculata; R. nutans = R. microspadix; R. buergersii, R. confeta. R. drepanophylla, R. obliquata and R. peekelii = R. schlechteri; R. apiculata; R. engleri [syn. R. palauensis Engl. & K. Krause (1921) non Koidz. (1916), R. forbesii, R.kanehirae and R. palauensis Koidz. (1916) = R. spathacea; R. graeffei and R. reineckei = R. spuria; R. ledermannii = R. versteegii.

Abstract:
The 18 Begonia (Begoniaceae) species now known from limestone and associated substrates in Sabah, Malaysia, are listed and a key provided for their identification. Twelve are described as new species: Begonia anthonyi Kiew, B. baturongensis Kiew. B. berhamanii Kiew, B. diwolii Kiew, B. heliostrophe Kiew, B. keena Kiew, B. lambii, B. layang-layang Kiew, B. madaiensis Kiew, B. melikopia Kiew, B. punbatuensis Kiew and B. urunensis Kiew that belongs to sect. Diploclinium (lindl.) A.D.C.. reasons for placing are given.  Begonia is the most speciose genus on limestone in Sabah.  Of the 18 species, only one , B. gueritziana, is widespread and also found on non-limestone substrates.  Of the others, 12 species are known from single limestone hills and 5 are from hills within the same area.  Habitat disturbance, which increases the risk of fire, therefore poses the greatest threat to the conservation of these species.

In line with recent opinion favouring the splitting of the genus Myrica L. sensu lato, new combinations in Morella Lour. {Morella esculenta (Buch.-Ham.) I.M. Turner and M. javinica (Blume) I.M. Turner) are provided for the two Malesian species of Myricaceae.

Abstract:
The traditional approach to the classification of Musa species (Musaceae) is the separation into four sections {Musa, Rhodochlamys, Callimusa and Australimusa) based on chromosome number and morphological characters. The sectional placing of Musa beccarii N.W Simmonds is still unresolved due to its unique chromosome number. The sections of two new species from Sabah, Malaysia, M. monticola (Hotta ex) Argent and M. suratii Argent, were also undetermined. This study employs Amplified Fragment Length Polymorphism (AFLP) as a molecular tool to determine the sectional placement of these three species within Musa. Eight primer combinations generated 17 genetic markers, which confirmed and M monticola in sect. Australimusa, while results show M. suratii falling between sect. Callimusa and sect Australimusa suggesting that the two sections can no longer be maintained as distinct.

Abstract:
Five new species of Madhuca, M. engkikiana, M. markleeana, M. multinervia, M. ochracea. and M. silamensis, are described and two new combinations, M. daemonica and M. prolixa, and two new names, M. cheongiana and M. kuchingensis, are proposed as a consequence of the reduction of Ganua to Madhuca.

Abstract:
The pollen grains of 20 Durio species and 5 clones of D. zibethinus were studied. Based on the exine sculpture of the pollen, the Durio species can be divided into three major groups, i.e. psilate, scabrate and verrucate. However, variation in the exine sculpture is also exhibited in D. zibethiniis, D. malaceensis and D. singaporensis. In addition, pollen size and wall thickness provide useful taxonomic evidence in distinguishing certain species. Pollen characters, however, could be used as supplementary characters in the identification of Durio species.

Abstract:
In 1933. C.E. Carr assembled a large collection of orchids from Gunung Kinabalu, Sabah, Malaysia. The herbarium specimens were duly processed and distributed, but the matching alcohol samples remained inaccessible until recently. Now, these samples have also been processed and are available for examination in the Singapore Botanic Gardens Herbarium. The material of the genus Bulbophyllum was studied; it yielded three new species and two new records for the Kinabalu area. These are described and annotated.

Abstract:
Notheria, gen. nov. (Orchidaceae. Eriinae), is described, with N. diaphana, sp. nov., as type species. On account of similarity, it is assumed to be closely related to both Eria Lindl., and Ceratostylis Blume; however Notheria differs from both in having a footless column and a lip with a distinct spur. The genus is endemic to Sulawesi (Indonesia).

Abstract:
Bulbophyllum setuliferum sp. nov. (sect. Hirtula) from Peninsular Malaysia is described. Bulbophyllum atratum J.J, Smith, of the same section, until now known only from Sumatra, is a new record for Peninsular Malaysia.
