Three new species of Dendrochilum (Orchidaceae) and their phylogenetic positions according to plastid and nuclear ribosomal ITS sequences

Henrik A. Pedersen, Barbara Gravendeel & Deden Mudiana

Three new species of the Southeast Asian orchid genus Dendrochilum Blume are described. All three seem to belong to the phenetically defined subgenus Platyclinis (Benth.) Pfitzer. As indicated by the name, D. celebesense H.A. Pedersen & Gravend. originates from Sulawesi. The geographic origins of D. coccineum H.A. Pedersen & Gravend. and D. warrenii H.A. Pedersen & Gravend., on the other hand, are unknown, but parsimony analyses of sequences of the plastid accD-psaI intergenic spacer and nuclear ribosomal ITS1-5.8S-ITS2 region and morphological affinities suggest they should both be counted as members of the Philippine flora.

Devogelia (Orchidaceae), a new genus from the Moluccas and New Guinea

A. Schuiteman

The new orchid genus Devogelia from the Moluccas and New Guinea is described and illustrated. Its possible affinities are discussed and it is tentatively concluded that Devogelia belongs either to the tribe Cymbidieae or to the Malaxideae. So far a single species, here described as D. intonsa Schuit., is known, which occurs as a locally abundant terrestrial in lower montane forest.

Revision of Pimelodendron (Euphorbiaceae) in Malesia

Tutie Djarwaningsih

Pimelodendron comprises five species. Four species were already known (P. amboinicum, P. griffithianum, P. macrocarpum, P. zoanthogyne). One Sumatran species is to separate in the rest of Pimelodendron without naming it (Pimelodendron spec. nov.?). One name is excluded (P. dispersum = Actephila excelsa var. javanica), while P. naumannianum is regarded as a synonym of P. amboinicum.

Revision of Annesijoa, Elateriospermum and the introduced species of Hevea in Malesia (Euphorbiaceae)

Hoang Van Sam & Peter C. van Welzen

Annesijoa is an endemic monotypic genus from New Guinea with as single species A. novoguineensis. Elateriospermum is also monotypic (E. tapos) and found in West Malesia. The South American genus Hevea comprises about 10 species. One species (H. brasiliensis) is presently cultivated worldwide in plantations for its rubber and has become one of the major economic products of SE Asia. Two other species, H. guianensis and H. pauciflora are sometimes present in Malesian botanical gardens.

A new species of Afrothismia (Burmanniaceae; tribe: Thismieae) from the western foothills of Mount Cameroon

Th. Franke, M.N. Sainge& R. Agerer

Afrothismia foertheriana, a new species of Burmanniaceae (tribe: Thismieae) from the peripheral zone of the Onge Forest Reserve in Cameroon’s Southwest Province is described and illustrated. The papillose, multicellular floral trichomes, the tepal’s erose margins, the small, zygomorphic perianth mouth and the dull purplish brown coloration give A. foertheriana a distinctive appearance within the genus. The species is here assessed as being critically endangered.

Chromosome numbers and other karyological data of four Stemona species (Stemonaceae) from Thailand

Markus Hartl & Michael Kiehn

Chromosome numbers and other karyological data of four Stemona spp. (Stemonaceae) from Thailand are reported. Three taxa (S. collinsae Craib, S. kerrii Craib and an unidentified species) exhibit 2n = 14 chromosomes, for S. curtisii Hook.f. a range of 2n = 13–16 was established. Based on the counts of c. 30% of the species of Stemona, x = 7 is very likely to be the basic number for the genus. Chromosome size and morphology of the investigated species are compared with literature data and show differences that might be of importance for infrageneric classification. In this connection the taxonomic position of the genus Pentastemona from Sumatra is also discussed.

The naming, introduction and classification of citrus crops and their allies is outlined. Traditional medicinal use and ‘Western’ applications in the treatment of scurvy and obesity, the prevention of AIDS, and in contraception is reviewed. Names for the commercially significant citrangequat (Citrus x georgiana) and the ‘sunrise lime’ or ‘faustrimedin’ (C. x oliveri) are provided.
