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/10.5735/085.055.011403217nas a2200193 4500008004100000022001400041245016200055210006900217300001400286520251900300100002302819700002602842700002702868700001802895700001702913700001802930700001902948856005602967 2018 eng d a0373-296700aEnlarging the monotypic Monocarpieae (Annonaceae, Malmeoideae): recognition of a second genus from Vietnam informed by morphology and molecular phylogenetics0 aEnlarging the monotypic Monocarpieae Annonaceae Malmeoideae reco a261–2753 aChaowasku, T., A.

Enlarging the monotypic Monocarpieae (Annonaceae, Malmeoideae): recognition of a second genus from Vietnam informed by morphology and molecular phylogenetics. Candollea 73: 261–275. In English, English abstract. DOI: http://dx.doi.org/10.15553/c2018v732a11 Recent botanical expeditions in central Vietnam yielded an unknown species of Annonaceae that could not be confidently identified to subfamily, tribe, and genus. Preliminary BLAST® searches based on plastid data have suggested that this taxon is genetically closely-related to the following tribes of subfamily Malmeoideae: Malmeeae, Fenerivieae, Maasieae, Phoenicantheae, Dendrokingstonieae, Monocarpieae, and Miliuseae. Using representatives of Piptostigmateae, another tribe of Malmeoideae, as outgroups and including representatives of all other tribes of Malmeoideae, molecular phylogenetic analyses of seven combined plastid markers (rbcL, matK, ndhF, ycf1 exons; trnL intron; trnL-trnF, psbA-trnH intergenic spacers) inferred the enigmatic Vietnamese taxon as belonging to the monotypic tribe Monocarpieae. Detailed morphological comparisons between this taxon and its sister group, Monocarpia Miq., warranted the recognition of a second genus of Monocarpieae to accommodate our unknown taxon: Leoheo Chaowasku with a single species, Leoheo domatiophorus Chaowasku, D.T. Ngo & H.T. Le. The morphology of the new genus agrees well with the diagnostic traits of Monocarpieae, e.g., a percurrent tertiary venation of the leaves, a highly reduced number of carpels per flower, enlarged and lobed stigmas, multiple ovules/seeds per ovary/monocarp, considerably large monocarps with a hardened pericarp when dry, and spiniform ruminations of the endosperm. However, the new genus does not exhibit two characteristic features of Monocarpia: terminal inflorescences and generally distinct intramarginal leaf veins. In addition, the new genus possesses three autapomorphic characters: hairy domatia on the lower leaf surface, longitudinal ridges on the monocarp surface, and subsessile monocarps with a stout stipe. The tribe Monocarpieae is consequently enlarged to include the genus Leoheo. The enlarged Monocarpieae, along with the recently established monotypic tribe Phoenicantheae and two other related tribes, Dendrokingstonieae and Miliuseae, are discussed.

It belongs to a clade with campanulate flowers and inner petals that are generally tightly appressed from the base to more or less the midpoint at anthesis. The new species is remarkable in possessing a strongly recurved apex of the inner petals at anthesis and can be principally differentiated from its morphologically closest species, M. pumila Chaowasku and M. filipes Ridl., both from Peninsular Thailand, by the higher number of stamens and carpels per flower and horseshoe-shaped stigmas.

Four new species, M. anomalocarpa, M. chiangraiensis, M. gardneri, and M. maxiflora, are described. Meiogyne anomalocarpa has the widest distribution of any Meiogyne species in Thailand, but the other three species are narrowly distributed. Meiogyne anomalocarpa and M. maxiflora have the axillary inflorescences typical of the genus, but in M. chiangraiensis and M. gardneri the inflorescences are flagelliform and arise from the lower trunk, a morphology previously unreported from members of this genus. The presence of M. chiangraiensis in northern Thailand extends the range of the genus significantly northward. Meiogyne caudata is reported as new to the flora of Thailand. Several Meiogyne specimens from southernmost Thailand previously identified as M. virgata in the past by various workers were found to be more similar to M. kanthanensis, recently described from Perak, Peninsular Malaysia. A key is provided for the eight species currently recognized as occurring in the country.10aAnnonaceae10aSoutheast Asia10ataxonomy10atree diversity1 aJohnson, David, M1 aLiu, Ming-Fai1 aSaunders, Richard, M K1 aChalermglin, Piya1 aChaowasku, Tanawat uhttps://www.tci-thaijo.org/index.php/ThaiForestBulletin/article/view/16591902606nas 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/art0000300646nas a2200181 4500008004100000020001400041245014500055210006900200300001400269490000700283100002000290700002100310700002300331700002600354700001700380700001900397856004800416 2014 eng d a0040-026200aA decade of uncertainty: Resolving the phylogenetic position of Diclinanona (Annonaceae), including taxonomic notes and a key to the species0 adecade of uncertainty Resolving the phylogenetic position of Dic a1244-12520 v631 aErkens, Roy, HJ1 aChatrou, Lars, W1 aChaowasku, Tanawat1 aWestra, Lubbert, Y Th1 aMaas, Jan, W1 aMaas, Paul, JM uhttps://annonaceae.myspecies.info/node/572800667nas a2200181 4500008004100000020001400041245015900055210006900214300001200283490000800295100002300303700002200326700003000348700001900378700001900397700002100416856004800437 2014 eng d a0002-912200aA plastid DNA phylogeny of tribe Miliuseae: Insights into relationships and character evolution in one of the most recalcitrant major clades of Annonaceae0 aplastid DNA phylogeny of tribe Miliuseae Insights into relations a691-7090 v1011 aChaowasku, Tanawat1 aThomas, Daniel, C1 avan der Ham, Raymond, WJM1 aSmets, Erik, F1 aMols, Johan, B1 aChatrou, Lars, W uhttps://annonaceae.myspecies.info/node/571200655nas 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/570201914nas a2200217 4500008004100000245016100041210006900202300001000271490000700281520119000288653001901478653001501497653002401512653001601536653001301552653001301565100002001578700002301598700002701621856004801648 2010 eng d00aAn extended phylogeny of Pseuduvaria (Annonaceae) with descriptions of three new species and a reassessment of the generic status of Oreomitra0 aextended phylogeny of iPseuduvaria iAnnonaceae with descriptions a30-390 v353 aThree new species of Pseuduvaria (Annonaceae) from Peninsular Thailand and Peninsular Malaysia are described and named as P. fragrans, P. gardneri, and P. glossopetala.

A clade consisting of Winitia and Stelechocarpus is strongly supported as sister to Sageraea, which is monophyletic with strong support. Winitia consists of two species, one of which (W. expansa) is proposed as a new species endemic to Thailand, whereas one new combination (W. cauliflora) is made. The new genus is primarily characterized by (1) multicolumellar stigmas (≥ 5 columns per stigma) and (2) pollen grains with a very thin tectum, a more or less columellate/coarsely granular infratectum, and a very distinct basal layer. The macromorphology and pollen morphology of the three genera (Stelechocarpus, Winitia, and Sageraea) are highlighted.1 aChaowasku, Tanawat1 aVan der Ham, Raymond, W. J.
