''Coleotrype'' is a genus of perennial monocotyledonous flowering plants in the dayflower family. It is found in Africa and Madagascar.〔(Kew World Checklist of Selected Plant Families )〕 The genus is characterised by its extremely contracted inflorescences with each unit being subtended by a relatively large bract, and the petals that form a short tube at the base in which the stamens are attached to it. Flowers may be either zygomorphic or actinomorphic, and anthers release their pollen either through a pore at the tip or slits down the sides. They are typically encountered in forest understories.〔Faden, R. (2012). Commelinaceae. Flora of Tropical East Africa: 1-244. 〕 Analysis of DNA sequences has shown that ''Coleotrype'' is most closely related to the genus ''Amischotolype'', while these two are in turn most closely related to the genus ''Cyanotis'' plus its very close relative ''Belosynapsis''. These four genera form a clade that is found only in the Old World, while all of its immediate ancestors are present only in the New World. ;Species〔 # ''Coleotrype baronii'' Baker - Madagascar # ''Coleotrype brueckneriana'' Mildbr. - Kenya, Tanzania # ''Coleotrype goudotii'' C.B.Clarke - Madagascar # ''Coleotrype laurentii'' K.Schum. - western + central Africa # ''Coleotrype lutea'' H.Perrier - Madagascar # ''Coleotrype madegascarica'' C.B.Clarke - Madagascar # ''Coleotrype natalensis'' C.B.Clarke - Swaziland, Mozambique, Zimbabwe, South Africa # ''Coleotrype synanthera'' H.Perrier - Madagascar # ''Coleotrype udzungwaensis'' Faden & Layton - Tanzania # ''Coleotrype vermigera'' H.Perrier - Madagascar ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Coleotrype」の詳細全文を読む スポンサード リンク
