Huberantha floribunda does not fall into Huberantha clade, but is retrieved as the sister group of Miliusa with no support, necessitating the recognition of a new genus, to accommodate this species. Polyalthiopsis Chaowasku gen. nov. along with Huberantha and Miliusa form an unsupported to weakly supported clade within the tribe Miliuseae. Morphology of Polyalthiopsis is somewhat intermediate between morphologies of Huberantha and Miliusa. It primarily differs from Huberantha by often possessing unequal petal whorls and a seed raphe that is broadly grooved and partially slightly raised in the middle. Polyalthiopsis differs from Miliusa mainly by having a dilated truncate connective apex of the stamens and outer petals that are much larger than the sepals. In addition, Huberantha luensis (Pierre) Chaowasku, a new combination for Polyalthia luensis is made based on an integrative approach of morphological examination coupled with molecular phylogenetic inferences.1 aChaowasku, Tanawat1 aDamthongdee, Anissara1 aJongsook, Hathaichanok1 aNuraliev, Maxim, S.1 aNgo, Dung, T.1 aLe, Hung, T.1 aLithanatudom, Pathrapol1 aOsathanunkul, Maslin1 aDeroin, Thierry1 aXue, Bine1 aWipasa, Jiraprapa uhttp://www.bioone.org/doi/abs/10.5735/085.055.011402606nas a2200181 4500008004100000245014900041210006900190300001400259490000700273520193400280100001402214700001802228700002202246700002302268700001902291700002702310856008702337 2018 eng d00aA new Annonaceae genus, Wuodendron, provides support for a post-boreotropical origin of the Asian-Neotropical disjunction in the tribe Miliuseae0 anew Annonaceae genus Wuodendron provides support for a postboreo a250–2660 v673 aRecent molecular and morphological studies have clarified generic circumscriptions in Annonaceae tribe Miliuseae and resulted in the segregation of disparate elements from the previously highly polyphyletic genus Polyalthia s.l. Several names in Polyalthia nevertheless remain unresolved, awaiting assignment to specific genera, including Polyalthia litseifolia. Phylogenetic analyses of seven chloroplast regions (atpB-rbcL, matK, ndhF, psbA-trnH, rbcL, trnL-F, ycf1; ca. 8.3 kb, 116 accessions, including representatives of all currently accepted genera in subfamily Malmeoideae) unambiguously placed Polyalthia litseifolia in a clade with three accessions from Thailand, which have previously been shown to represent an undescribed genus sister to the Neotropical clade (Desmopsis, Sapranthus, Stenanona, Tridimeris) in the predominantly Asian tribe Miliuseae. The collective clade is sister to Meiogyne. Polyalthia litseifolia shares several diagnostic characters with most species in the Neotropical genera and Meiogyne, including: petals that are similar in shape and size in both whorls; multiple ovules per ovary in one or two rows; and lamelliform endosperm ruminations. It is distinct in being deciduous, bearing subpetiolar buds and having inflorescences growing from the leaf scar of the dropped leaves. Morphological comparisons and phylogenetic analyses corroborate its recognition as a new genus, which is formally described and illustrated here as Wuodendron. Polyalthia litseifolia is furthermore found to be conspecific with Desmos praecox, and the latter name is used as the basis for the name of the type. Molecular divergence time estimates under an uncorrelated lognormal relaxed clock place the Wuodendron-Neotropical clade split within the Miocene (ca. 14–12 Ma), highlighting the importance of post-boreotropical dispersal and vicariance in shaping intercontinental tropical disjunctions in Annonaceae.1 aXue, Bine1 aTan, Yun-Hong1 aThomas, Daniel, C1 aChaowasku, Tanawat1 aHou, Xue-Liang1 aSaunders, Richard, M K uhttps://www.ingentaconnect.com/contentone/iapt/tax/2018/00000067/00000002/art0000300655nas a2200169 4500008004100000020001400041245018700055210006900242300001200311490000700323100001400330700002200344700002300366700002200389700002600411856004800437 2014 eng d a0363-644500aMolecular phylogenetic support for the taxonomic merger of Fitzalania and Meiogyne (Annonaceae): New nomenclatural combinations under the conserved name Meiogyne0 aMolecular phylogenetic support for the taxonomic merger of iFitz a396-4040 v391 aXue, Bine1 aThomas, Daniel, C1 aChaowasku, Tanawat1 aJohnson, David, M1 aSaunders, Richard, MK uhttps://annonaceae.myspecies.info/node/5702
