Chaowasku, T., A. Damthongdee, H. Jongsook, D.T. Ngo, H.T. Le, D.M. Tran & S. Suddee (2018). 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/c2018v732a11Recent botanical expeditions in central yielded an unknown species Annonaceae that could not be confidently identified to subfamily, tribe, genus....
The generic status of Winitia Chaowasku (Annonaceae Juss., Miliuseae Hook.f. & Thomson) is reaffirmed by an extensive phylogenetic reconstruction using seven plastome regions (matK, ndhF, rbcL, ycf1 exons; trnL intron; psbA-trnH, trnL-trnF intergenic spacers) and including, among others, accessions plus two its sister group, Stelechocarpus Thomson. results disclosed a maximally supported clade Winitia, as well Stelechocarpus. relationship the genera still rather poorly branch uniting...
Abstract Annonaceae is a major tropical plant family particularly diverse in rain forests of the world. Although classification and systematics has significantly improved over past decade, most recent was based on reduced set plastid markers incomplete genus‐level taxon sampling. This recognised 4 subfamilies 20 tribes. Yet, several important problems persisted, especially phylogenetic placement African genus Meiocarpidium , resolution intertribal relationships within subfamily Malmeoideae,...
The identity of an enigmatic species Huberantha floribunda (Annonaceae) is reassessed using molecular phylogenetic analyses up to seven combined plastid markers (matK, ndhF, rbcL, ycf1 exons; trnL intron; trnL-trnF, psbA-trnH intergenic spacers), constituting ca. 7 kbp. does not fall into clade, but retrieved as the sister group Miliusa with no support, necessitating recognition a new genus, accommodate this species. Polyalthiopsis Chaowasku gen. nov. along and form unsupported weakly...
Thirteen species of Friesodielsia Steenis (Annonaceae) and 11 representatives related genera were included in molecular phylogenetic analyses using up to six plastid DNA regions (psbA-trnH, trnL-trnF intergenic spacers; trnL intron; matK, ndhF, rbcL exons). The results support the recognition a new species, F. lalisae Damth., Baka & Chaowasku from Narathiwat, S Thailand, as belonging one two major clades Friesodielsia. members this clade show outer petals that separate at anthesis have...
Artabotrys R. Br. is one of the larger genera Annonaceae with over 100 species distributed throughout palaeotropics plus northern Australia. Although genus morphologically very well circumscribed, delimitation quite problematic owing to overlapping morphological characteristics. In Thailand, 20 have been reported, including A. multiflorus C. E. Fisch. Detailed comparisons type specimen from Myanmar revealed that occurring in Kanchanaburi Province Thailand represents a new herein described as...
Miliusa chantaburiana Damthongdee & Chaowasku, a new species of Annonaceae from SE Thailand, is described and illustrated. It belongs to clade with campanulate flowers inner petals that are generally tightly appressed the base more or less midpoint at anthesis. The remarkable in possessing strongly recurved apex anthesis can be principally differentiated its morphologically closest species, M. pumila Chaowasku filipes Ridl., both Peninsular by higher number stamens carpels per flower...
The delimitation of the genera Pyramidanthe and Mitrella in tribe Uvarieae family Annonaceae is assessed by molecular phylogenetic analyses morphological re-evaluation. Using up to six plastid DNA regions (matK, ndhF, rbcL exons; trnL intron; psbA-trnH, trnL-trnF intergenic spacers) including, among others, two accessions five Mitrella, resulting phylogeny shows that are recovered a clade sister Fissistigma clade. Pyramidanthe-Mitrella composed trichotomy: consisting clades containing...
Meiogyne rubra Jaikhamseub, Damth. & Chaowasku sp. nova and M. vietnamica T.A. Le (Annonaceae) from Vietnam are described illustrated. Molecular phylogenetic reconstructions based on up to eight plastid DNA regions (matK, ndhF, rbcL ycf1 exons; trnL intron; ndhF-rpl32, rpl32-trnL trnL-trnF intergenic spacers) incorporating 33 accessions (31 species) of were performed. The two new species, as well anomalocarpa, caudata, chiangraiensis subsessilis included in molecular analyses for the first...

Drepananthus khaosoi sp. nov., a new species from southern Thailand is described and illustrated. It morphologically most similar to D. ridleyi, especially in the very narrow elongated petals, but differs leaf blade size, base, monocarp shape appearance, width, length of stipe, pericarp thickness seed arrangement. Molecular phylogenetic analyses using chloroplast DNA regions (matK rbcL exons; trnL intron; atpB-rbcL, psbA-trnH trnL-trnF intergenic spacers) including 18 confirm monophyly...
Miliusa majestatis Damth., Sinbumr. & Chaowasku (Annonaceae), a new species from southern Thailand, is described and illustrated. Based on molecular phylogenetic analysis using up to seven plastid DNA regions (matK, ndhF, rbcL ycf1 exons; trnL intron; psbA-trnH trnL-trnF intergenic spacers) including, among others, 35 accessions (representing 34 species) of Miliusa, the belongs one four unnamed major clades in genus. Within that clade genus general, M. unique having constricted inner petals...
On the basis of expansive molecular phylogenetic analyses genus Miliusa (Annonaceae) utilising up to seven plastid DNA regions, four major clades are identified: A, B, C and D. Members clade possess axillary inflorescences crescent-shaped semicircular glandular structures at base or (slightly) higher inside inner petals. In this clade, accessions M. mollis recovered as a monophyletic group, divided into two clades. One them is recognised new species, microphylla, which differs from other (M....
An extended molecular phylogeny of the genus Dasymaschalon (Annonaceae) has been reconstructed using up to six plastid DNA regions (matK, ndhF, rbcL exons; trnL intron; psbA-trnH, trnL-trnF intergenic spacers). The results unraveled non-monophyly a widely distributed D. dasymaschalum. A lineage dasymaschalum native Java and cultivated at Bogor Botanical Garden represents true dasymaschalum, whereas name Pelticalyx argentea is applicable distantly related clade from mainland Asia. argenteum...
Background and aims – Recent botanical expeditions in Ranong Province, southern Thailand yielded unidentifiable collections of Orophea subgenus Sphaerocarpon (Annonaceae). To elucidate the taxonomic status these collections, detailed morphological examinations comparisons with morphologically similar species are made.Material methods This study followed standard practices herbarium taxonomy. Specimens spp. BKF, CMUB, L, QBG herbaria were studied. Digitised type specimens deposited BM, E, G,...
Pseuduvaria khaosokensis Yoosukkee & Chaowasku (Annonaceae), a new species from Surat Thani Province, southern Thailand, is described and illustrated. A plastid phylogeny with 55 accessions of six DNA regions (matK, rbcL exons; trnL intron; atpB–rbcL, psbA–trnH, trnL–trnF intergenic spacers) included placed the as sister group to P. setosa, widespread occurring in southwestern well Peninsular Malaysia. The two are primarily distinguishable each other by differences indumentum on young twigs...
A new combination Miliusa parvifolia (Kurz) Damth. & Chaowasku (Annonaceae, Miliuseae) is made based on Popowia Kurz. The name M. parviflora Ridl. reduced to a heterotypic synonym of parvifolia.
