New nomenclatural combinations are furthermore validated in Goniothalamus (Annonaceae), following the successful conservation of the generic name over Richella. Two species names in Richella are here transferred to Goniothalamus as G. monospermus (A. Gray) R. M. K. Saunders and G. obtusatus (Baill.) R. M. K.

Phylogenetic analyses of eight chloroplast regions (matK, ndhF, ndhF-rpl32, psbA-trnH, rbcL, rpl32-trnL, trnL-F, and ycf1; ca. 9.2 kb, 66 taxa) unambiguously placed D. saccopetaloides in a subclade of tribe Miliuseae, nested among the genera Monoon, Neo-uvaria, Phaeanthus, Sageraea, and Stelechocarpus. This relationship was also supported by endosperm rumination patterns in the seed; other morphological characters furthermore indicated that D. saccopetaloides has closer affinities with Monoon, Neo-uvaria, and Phaeanthus rather than either Sageraea or Stelechocarpus. Desmos saccopetaloides is distinguished from these genera by its leaf-opposed inflorescences, sepaloid outer petals, saccate inner petals with basal glandular tissue, moniliform monocarps with uniseriate seeds, and rectangular disulculate pollen with two “cryptoapertures”. On the basis of the combined molecular phylogenetic and morphological data, we propose a new genus, Wangia, to accommodate D. saccopetaloides. The molecular phylogenetic analyses furthermore indicated that Desmos yunnanensis belongs to the genus Dasymaschalon: examination of the type collections revealed that it is conspecific with Dasymaschalon obtusipetalum, although the combination Dasymaschalon yunnanense has nomenclatural priority.10aDasymaschalon10amolecular phylogeny10amorphology10aPhaeanthus10ataxonomy1 aGuo, Xing1 aWang, Jing1 aXue, Bine1 aThomas, Daniel, C1 aSu, Yvonne, C F1 aTan, Yun-Hong1 aSaunders, Richard, M K  uhttps://annonaceae.myspecies.info/node/5147
