Section Speciosae Pfitzer & Kraenzl. of the genus Coelogyne Lindl. is revised. Sixteen species are recognized, including one new (C. tommii) and one dubious species (C. dichroantha). Three former varieties are raised to subspecies level (C. speciosa subsp. speciosa, subsp. incarnata and subsp. fimbriata). Two species formerly included in sect. Speciosae by several authors are excluded (C. eberhardtii and C. lawrenceana).

A revision of the genus Faradaya F. Muell. (Labiatae) is presented with taxonomic history, keys, full descriptions, distribution maps and ecological and ethnobotanical notes. Only three species are recognised: F. amicorum (Seem.) Seem., F. lehuntei (Horne ex Baker) A.C. Sm. and F. splendida F. Muell.; fifteen names are put into synonymy for the first time.

Although not the ?rst publication validating the generic name Rafflesia, Robert Brown’s ?rst classic paper on Rafflesia arnoldii was issued as a preprint in April 1821, antedating the publication of the possibly threatening name, R. titan Jack; Brown’s second paper on the genus was also ?rst distributed as a preprint, in September 1844. New names ?rst published in these papers are listed and remarks on the typi?cation of Malesian species (two lectotypi?cations proposed) added. Rafflesia horsfieldii is apparently conspeci?c with R. patma, which, if proved, should prompt a move for the conservation of the later name R. patma. Precise datings for certain parts of the Proceedings and Transactions of the Linnean Society are presented and, as a result, it is necessary to propose a new combination, Thottea piperiformis (Griff.) Mabb. (Aristolochiaceae).

Four different analyses of Thai Syzygium show, with very small discrepancies, that one smaller monophyletic and one larger polyphyletic group can be recognised. The smaller monophyletic group warrants sectional rank as Syzygium section Jambosa and consists of S. anacardiifolium, S. aqueum, S. diospyrifolium, S. formosum, S. foxworthianum, S. jambos, S. lakshanakarae, S. malaccense, S. megacarpum, S. papillosum, S. pseudoformosum, S. pycnanthum, S. samarangense, S. scortechinii and S. siamense.

A brief summary of the present taxonomic position in Agalmyla Blume (Gesneriaceae) is given. Six new species are described, A. bicolor, A. exannulata and A. remotidentata from Sulawesi, A. macrocalyx from Borneo (Sarawak), A. samarica from the Philippines (Samar) and A. manuselae from the Moluccas (Seram). The plant long known as Dichrotrichum ternateum de Vriese is transferred to Agalmyla, under its oldest epithet, as A. elongata (Blume) B.L. Burtt, and two other early names of species from New Guinea are also transferred as A. chalmersii (F. Muell.) B.L. Burtt and A. triflora (Valeton) B.L. Burtt.

Studies on the genus Ardisia Sw. for Flora Malesiana have led to the reduction of 95 taxa to synon-ymy, seven species to the infraspeci?c level: A. demissa Miq. var. bambusetorum (King & Gamble) C.M. Hu, A. polysticta Miq. subsp. punctipelata (Merr.) C.M. Hu, A. ternatensis Scheff. var. forstenii (Scheff.) C.M. Hu, A. darlingii Merr. subsp. podadenia (Stone) C.M. Hu, A. imperialis K. Schum. var. novoguineensis (Mez) C.M. Hu, A. pubicalyx Miq. var. collinsae (Fletcher) C.M. Hu, A. tahanica King & Gamble subsp. eucalyptifolia (Stone) C.M. Hu, and two new combinations are made: A. forbesii S. Moore var. cataractorum (Stone) C.M. Hu, A. fulva King & Gamble var. multiflora (Stone) C.M. Hu.

A phylogeny of the complete tribe Chrozophoreae is presented in order to establish the possible monophyly and relationships in subtribes Chrozophorinae (Chrozophora) and Doryxylinae (Doryxylon, Melanolepis, Sumbaviopsis, Thyrsanthera). Added are the other subtribes in tribe Chrozophoreae, the Speranskiinae (Speranskia) and Ditaxinae (Argythamnia, Caperonia, Chiropetalum, Ditaxis, Philyra). Outgroups are the genera Agrostistachys and Chondrostylis (tribe Agrostistachydeae).
The phylogeny shows two monophyletic groups, subtribe Speranskiinae together with Ditaxinae, and subtribe Chrozophorinae with Doryxylinae. The latter group is statistically well supported by a high bootstrap value. The ?rst group is weakly supported and collapses easily when the characters are selected somewhat differently. The former subtribes Chrozophorinae and Doryxylinae are united into one subtribe, Chrozophorinae. The remaining taxa in tribe Chrozophoreae, the monogeneric subtribe Speranskiinae and subtribe Ditaxinae are united into subtribe Ditaxinae. Within subtribe Chrozophorinae s.l. Chrozophora is sister taxon to all other taxa, followed by Thyrsanthera and Melanolepis. Doryxylon and Sumbaviopsis were apparently the last to separate. The differences between all, mainly monotypic, genera are quite large, therefore, the present delimitation is favoured over a suggested union of Doryxylon and Sumbaviopsis.

The Southeast Asian genus Melanolepis comprises two species, the very variable and widespread M. multiglandulosa (Reinw. ex Blume) Rchb.f. & Zoll. (from Taiwan and the Ryukyu Islands through-out Malesia up to Papua New Guinea and the Bismarck Archipelago) and M. vitifolia (Kuntze) Gagnep., endemic in Cambodia. The two species differ in dentation, incision, and hairiness of the leaves.

The genus Rauvolfia L. is revised in the Malesian region. Nine species are recognised including two new species, Rauvolfia kamarora Hendrian and R. oligantha Hendrian.

The genera Cynanchum and Vincetoxicum are revised for the Flora Malesiana area. For Cynanchum, nine species are recognized and one new subspecies is described. For Vincetoxicum, only one spe-cies, the widespread V. carnosum, occurs in the area. Five published species of Cynanchum have to remain obscure, because the types most likely got destroyed in Berlin.
