(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 &amp; 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 &amp; 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 &amp; 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/
