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/16591901056nas a2200157 4500008004100000022001400041245010000055210006900155260000800224300001200232490000800244520054800252100002700800700002200827856004900849 2019 eng d a1314-200300aMitrephora monocarpa (Annonaceae): a new species from Surat Thani Province, Peninsular Thailand0 aMitrephora monocarpa Annonaceae a new species from Surat Thani P cmay a73–800 v1213 aA new species, Mitrephora monocarpa R.M.K.Saunders & Chalermglin, sp. nov. (Annonaceae), is described from Surat Thani Province in Peninsular Thailand. It resembles two other species, M. alba Ridl. and M. keithii Ridl., with which it is broadly sympatric, but can be distinguished by its solitary flowers (not borne in thyrsoid inflorescences as in most other Mitrephora species), single carpel per flower (and hence single monocarp per fruit) and the lack of a monocarp stipe. A key to the nine Mitrephora species in Thailand is provided.1 aSaunders, Richard, M K1 aChalermglin, Piya uhttps://phytokeys.pensoft.net/article/34271/01523nas a2200157 4500008004100000022001400041245008100055210006900136300001200205490000700217520102600224100001701250700002201267700002701289856004901316 2018 eng d a1314-200300aTwo new species and two new records of Artabotrys (Annonaceae) from Thailand0 aTwo new species and two new records of Artabotrys Annonaceae fro a71–810 v953 aTwo new species of Artabotrys are described from Thailand. Artabotrys tanaosriensis J.Chen, Chalermglin & R.M.K.Saunders, sp. nov., is similar to A. oblanceolatus Craib but differs in its symmetrical, cuneate or decurrent leaf base, externally distinct outer petal blades and claws, deltoid and undulate outer petal blades, rhomboid and undulate inner petal blades and shorter, subsessile and slightly beaked monocarps. Artabotrys spathulatus J.Chen, Chalermglin & R.M.K.Saunders, sp. nov., is most similar to A. tanaosriensis but differs in having flat outer petal blades, broadly rhomboid outer petal claws, broadly spathulate and strongly concave inner petal blades and strongly beaked monocarps. Two new records for the Flora of Thailand are furthermore reported here: A. punctulatus C.Y.Wu ex S.H.Yuan and A. byrsophyllus I.M.Turner & Utteridge, which were previously confused with A. aeneus Ast and A. grandifolius King, respectively. A key to Artabotrys species indigenous to Thailand is provided here.1 aChen, Junhao1 aChalermglin, Piya1 aSaunders, Richard, M K uhttps://phytokeys.pensoft.net/article/23434/01822nas a2200241 4500008004100000020001400041245015400055210006900209260002900278300001000307490000800317520102200325653001901347653002401366653001701390653001601407653001601423100001701439700002001456700002201476700002701498856005501525 2010 eng d a1095-833900aMolecular phylogenetics of Uvaria (Annonaceae): relationships with Balonga, Dasoclema and Australian species of Melodorum0 aMolecular phylogenetics of iUvaria iAnnonaceae relationships wit bBlackwell Publishing Ltd a33-430 v1633 aAn extended molecular phylogenetic analysis of Uvaria (Annonaceae) is presented, using maximum parsimony, maximum likelihood and Bayesian methods, based on sequences of four plastid DNA regions (matK, psbA-trnH spacer, rbcL and trnL-F). 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. © 2010 The Linnean Society of London, Botanical Journal of the Linnean Society, 2010, 163, 33–43.10aclassification10amolecular phylogeny10anomenclature10aplastid DNA10aSYSTEMATICS1 aZhou, Linlin1 aSu, Yvonne, C F1 aChalermglin, Piya1 aSaunders, Richard, M K uhttp://dx.doi.org/10.1111/j.1095-8339.2010.01045.x
