The genus Alyxia is revised for Continental Asia and Malesia as the first part of a complete revision of the genus. Intergeneric and infrageneric relationships are discussed, as are the morphological characters for the whole genus. Problematic species and areas in need of further study are highlighted. Keys and descriptions for the species are given. 69 species are recognised of which 12 are newly described. These new species are Alyxia celebica, A. globosa, A. graciliflora, A. kwalotabaa, A. lackii, A. longiloba, A. manusiana, A. minutiflora, A. muguma, A. papuana, A. uniflora and A. vera.

An account of Pothos for Thailand and Indochina [taken here to comprise Myanmar, Cambodia, Lao P.D.R, Vietnam, subtropical China (Guangxi, Guangdong, Guizhou, Hainan, Hong Kong, Hubei, Sichuan, Yunnan)] and Taiwan is presented as a precursor of the forthcoming Flora of Thailand treatment. Fourteen species are recognised; one newly described and three validated for the first time. Extensive new synonymies are proposed. Pothos hermaphroditus (syn. Batis hermaphrodita), P. angustifolius (syn. P. scandens var. helferianus), P. leptospadix, P. cognatus (syn. P. scandens var. cognatus), P. zollingerianus (syn. P. scandens var. zollingerianus), P. horsfieldii, P. scandens var. javanica, P. scandens var. zeylanica, P. scandens var. sumatrana, and P. scandens forma angustior are reduced to P. scandens; Pothos balansae, P. cathcartii, P. chinensis var. lotienensis, and P. warburghii to P. chinensis; Pothos ellipticus, P. grandispathus, and P. ridleyanus to P. kingii; Pothos penicilliger to P. lancifolius; and Pothos peninsularis, P. kunstleri, and P. maingayi to P. curtisii. Brief discussions of geography, shoot architecture and life form are presented. Dichotomous and multi-access keys to species and a geographical species finder-list are provided. All species are illustrated.

A revision of the genus Phaeanthus Hook.f. & Thomson (Annonaceae) is presented. The genus comprises 8 species. A key to the fruiting and/or flowering specimens of the genus is included. The genus consists of shrubs to small-sized trees from Malesia and Vietnam. It is characterised by sepals and outer petals that are alike, numerous carpels and stamens, the latter truncate with a distinctive connective prolongation, monocarpous fruits, and leaves often drying dark brown to black. A phylogenetic analysis shows the monophyly of the genus and that Phaeanthus nutans can be considered the sister species of the remaining species.
