A recent molecular phylogenetic study, based on 51 species (including P. fragrans), elucidated the evolutionary relationships within the genus. The present study includes P. gardneri and P. glossopetala in the phylogenetic analyses using maximum likelihood and Bayesian inference methods, based on five chloroplast regions (psbA-trnH spacer, trnL-F, matK, rbcL, and atpB-rbcL spacer). The new nomenclatural combination Pseuduvaria phuyensis is also validated in accordance with the phylogenetic analyses which show that Craibella phuyensis and Pseuduvaria form a well-supported monophyletic clade. The new species and new nomenclature combination bring the total number of species in Pseuduvaria to 56. The taxonomic status of the enigmatic monotypic genus Oreomitra from New Guinea is furthermore evaluated, and the name shown to be synonymous with Pseuduvaria.}, keywords = {classification, NEW GUINEA, PENINSULAR MALAYSIA, SYSTEMATICS, taxonomy, THAILAND}, author = {Su, Yvonne C.

Fourteen species are recognized, including six endemics that are described as new to science (G. acehensis, G. alatus, G. dewildei, G. loerzingii, G. longistaminus and G. miquelianus). In addition, two species are newly recorded from Sumatra, viz. G. parallelivenius Ridl. (previously reported from Borneo), and G. wrayi King (previously reported from Peninsular Malaysia). The extensive nomenclatural confusion regarding the application of the names G. costulatus Miq. and G. opacus Bakh. f. is clarified: the names are shown to be synonymous, with the former having nomenclatural priority. The utility of specific taxonomic characters are also discussed, with particular emphasis on petal indumentum, staminal connective shape, ovary indumentum, stigma shape, monocarp size and shape, and seed indumentum. Biogeographical relationships in the genus are discussed, and the significance of the Barisan mountain range and the Quaternary volcanic tuffs around Lake Toba are highlighted as potential ecological barriers limiting dispersal.

The additional taxa include the monotypic West African genus Balonga, the monotypic South-East Asian genus Dasoclema and seven Australian representatives of the genus Melodorum. The results indicate that all of these taxa are nested within a well-supported clade otherwise consisting of Uvaria species, indicating that their taxonomic treatment needs to be reassessed. The distinguishing morphological characteristics of the taxa are re-evaluated and interpreted as specialized adaptations of the basic Uvaria structure. The genus Uvaria is accordingly extended following the transfer of these species, necessitating six new nomenclatural combinations and two replacement names.~{\textcopyright} 2010 The Linnean Society of London, Botanical Journal of the Linnean Society, 2010, 163, 33{\textendash}43.}, keywords = {classification, molecular phylogeny, nomenclature, plastid DNA, SYSTEMATICS}, isbn = {1095-8339}, url = {http://dx.doi.org/10.1111/j.1095-8339.2010.01045.x}, author = {Zhou, Linlin and Su, Yvonne C.
