''Palicourea'' is a plant genus in the family Rubiaceae. It contains about 200 species, which range in habit from shrubs to small trees, and is distributed throughout the New World tropics.〔Taylor (2008)〕 These plants are very closely related to ''Psychotria'' and in particular its subgenus ''Heteropsychotria''. Indeed, it seems to be nothing else but a distinctively-flowered offshoot of ''Heteropsychotria''; arguably, it would thus need to be merged into ''Psychotria'' to make that genus monophyletic. But on the other hand, ''Psychotria'' is extremely diverse already, so it is probably more practical to move the more distantly related species out of this genus and merge ''Heteropsychotria'' with ''Palicourea''.〔 The genus is not well studied. Most species are distylous, although a few on isolated Caribbean islands seem to have lost the trait. Flowers are in racemes, having no scent, and are normally pollinated by hummingbirds. Blue-black berries follow, and are thought to be distributed by birds.〔 Almost one-tenth of the ''Palicourea'' species are considered threatened by the IUCN, even though the conservation status has only been reviewed for those species that occur in Ecuador.〔IUCN (2008)〕 ==Selected species== * ''Palicourea anderssoniana'' * ''Palicourea anianguana'' * ''Palicourea asplundii'' * ''Palicourea azurea'' * ''Palicourea calantha'' * ''Palicourea calothyrsus'' * ''Palicourea calycina'' * ''Palicourea canarina'' * ''Palicourea candida'' * ''Palicourea consobrina'' * ''Palicourea corniculata'' * ''Palicourea cornigera'' * ''Palicourea fuchsioides'' * ''Palicourea gentryi'' * ''Palicourea heilbornii'' * ''Palicourea herrerae'' * ''Palicourea holmgrenii'' * ''Palicourea jaramilloi'' * ''Palicourea lasiantha'' * ''Palicourea lasiorrhachis'' * ''Palicourea latifolia'' * ''Palicourea lobbii'' * ''Palicourea macrocalyx'' * ''Palicourea prodiga'' * ''Palicourea sodiroi'' * ''Palicourea stenosepala'' * ''Palicourea subalatoides'' * ''Palicourea tectoneura'' * ''Palicourea wilesii'' 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「Palicourea」の詳細全文を読む スポンサード リンク
