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/514701275nas a2200193 4500008004100000245013300041210006900174300001200243490000700255520066200262653001000924653001600934653001400950653001700964653001600981653001300997100002301010856004801033 2013 eng d00aMiliusa codonantha (Annonaceae), a new species from the Indian eastern Himalaya, with a new combination, M. dioeca0 aiMiliusa codonantha iAnnonaceae a new species from the Indian ea a101-1050 v433 aA new species from the Indian eastern Himalaya, Miliusa codonantha, is described and illustrated. It chiefly differs from M. macrocarpa, its most morphologically similar species, in having smaller flowers and considerably fewer stamens and carpels per flower. In addition, a new combination is made for another species of Miliusa also occurring on the Indian subcontinent: M. dioeca (basionym: Uvaria dioeca). The two species as well as M. macrocarpa are placed in the previously recognized M. campanulata group. The names U. dioeca and its heterotypic synonym M. wallichiana are lectotypified.10aINDIA10aMalmeoideae10aMILIUSEAE10anomenclature10aSYSTEMATICS10ataxonomy1 aChaowasku, Tanawat uhttps://annonaceae.myspecies.info/node/4940
