Section Moniliformes Carr of the orchid genus Coelogyne is revised using morphological and molecular data. Twelve species are recognised, including two new ones (C. chanii and C. renae), and a dubious one (C. crassiloba). A combined analysis of morphological characters, and sequences of the nrDNA ITS region, matK gene, trnT-trnL intergenic spacer, trnL intron and trnL-trnF intergenic spacer supports the monophyly of the section as here recognised. Persistence of the rhizome scales, shape of the margin of the leaves, inflorescence type, shape of the rachis, its nodes and pedicel scars, indument of the floral bracts, lip size and depth of the sinus of the lateral lobes of the hypo-chile seem to be phylogenetically informative characters. Shape of the leaf blade, flowering mode, shape of the base and keels of the hypochile, shape of the apex of the lateral lobes and keels of the epichile and shape of the column show many parallelisms.

A revision of the genus Phyllagathis Blume is presented under a wider generic concept than used by earlier authors. A comprehensive synopsis of the genus is provided in the general part, where morphological characters and their variations are discussed. This paper will focus in particular on the species occurring in Burma, Thailand, Peninsular Malaysia (West Malaysia), and Sumatra. Here, the genus includes 10 species, most of which are endemic to Peninsular Malaysia, with only two species endemic to Thailand (P. siamensis and P. tuberosa), and two other also occurring outside the Malaysian political boundaries (P. rotundifolia and P. hispida). Part II of this paper will treat the species of Borneo and Natuna Island.

Seventeen new species of Freycinetia Gaudich. are described from groups of islands of New Guinea: Freycinetia admiraltiensis, F. amoena, F. formosula, F. granulata, F. lanceolata, F. nakanaiensis, F. novobritannica (Bismarck Archipelago), F. relegata, F. rossellana (Louisiade Archipelago), F. angusta, F. awaiarensis, F. boluboluensis, F. fergussonensis, F. goodenoughensis, F. lenifolia, F. normanbyensis (D’Entrecasteaux Islands), and F. woodlarkensis (Woodlark Island). Specific characters from both gross morphology and anatomy of fruits, seeds, and leaf auricles are used for the description.

Nepenthes vogelii Schuit. & de Vogel is described as a new species from Sarawak. It is compared with N. fusca Danser, from which it differs e.g. in the much smaller pitchers, of which the lid lacks appendages.

A revision is presented of the four genera of the SE Asian Chionachninae Clayton (Gramineae: Andropogoneae). Twelve species are recognised: nine (with two new combinations) in Chionachne R.Br. (incl. Sclerachne R.Br.) with an emended circumscription, one in the reinstated Cyathorhachis Nees ex Steud., one in Polytoca R.Br., and one in Trilobachne M. Schenck ex Henrard.

The genus Ptilothamnion Thur. in Le Jolis is represented in South Africa by three, or possibly four species: P. codicolum, P. polysporum, P. goukammae spec. nov., and reportedly P. subsimplex, all recorded after 1983. An earlier record of P. pluma is probably erroneous.
The new species differs from known representatives of the genus by producing strictly one involucral filament from the hypogenous cell and additionally one from the subhypogenous cell. Ptilothamnion is a widespread genus, but rarely with more than two species in any given regional flora. A critical comparison of the c. 12 species shows that very few characters are shared by all of them.
