Abstract:
A new species of banana, Musa johnsii Argent, is described and illustrated from Papua (formerly Irian Jaya), Indonesian New Guinea, and its possible position in the genus is discussed.

Abstract:
A Cryptocoryne from the Bukit Timah Nature Reserve, Singapore, identified for many years as C. griffithii  Schott, is recognised to be a new hybrid species: Cryptocoryne x timahensis Bastmeijer.  It is difficult to accurately determine its parents, but good candidates are C. nurii Furtado and C. cordata Griff., both native to Johore, Peninsular Malaysia.

Abstract:
An alpha-taxonomic account of Bornean Rhaphidophora is presented as a precursor to the forthcoming Flora Malesiana Araceae treatment. Thirteen species are recognised, none novel. Rhaphidophora elliptica Ridl. 1905 {non 1908 = R. elliptifolia Merr.) and R. megaspema Engl. treated respectively as synonyms of R. montana (Blume) Schott and R. puberula Engl. by Boyce (1999), are resurrected as Bornean endemics. New synonyms are: Scindapsis havilandii Ridl., Rhaphidophora jaculiformis Alderw., R. subfalcata M. Hotta into R. megasperma, and R. nigrescens Ridl. into R. sylvestris (Blume) Engl. 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. One species {R. dahlii Engl.) is treated as doubtful. A dichotomous key to species is provided. All species are illustrated.

Abstract:
Cytological observations were made on two recently described new Bornean species of Musa L., M. monticola and M. suratii both have 2n = 20. Taxonomic and biogeographic implications are discussed.

Abstract:
Etlingera pieeae Khaw from the Temenggor Forest Reserve in Perak. Peninsular Malaysia, is described as a new species. Including this new species, there are 12 Etlingera species in Peninsular Malaysia for which a key and descriptions are provided

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.

Abstract:
Irmscher's name, Begonia conipila, is validated for the striking species that grows on the Melinau limestone in Sarawak, Borneo.

Abstract:
In the genus Diospyros, seven new species (D. beccarioides Ng, D. brainii Ng, D. crockerensis Ng, D. keningauensis Ng. D. Iunduensis Ng. D. multinervis Ng and D. parabuxifolia Ng) and six new varieties (D. curranii Merr. var. kalimantanensis Ng; D. ferruginescens Bakh. var. rufotomentosa Ng; D. lanceifolia Roxb. var. iliaspaiei Ng, var. renageorgei Ng, var. saliciformis Ng: D. penibukanensis Bakh. var. scalarinervis Ng) are described. Thirty species or varieties are reduced to synonymy.

Abstract:
A recent, small collection of mosses from Mt. Halcon, Mindoro Island, the Philippines, has yielded two new records for the country {Rhacocarpus alpinus (Wright) Par. and Dicranoloma daymannianum Bartr.) and eight new records for the island. Relevant ecological, morphological and biogeographical notes for the 15 species collected are provided.

Abstract:
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.
