The Hylocereeae are a tribe of cacti. Found in the tropical forests of Central America, they are climbers or epiphytes, unlike most cacti. In the classification of the International Cactaceae Systematics Group of the International Organization for Succulent Plant Study, the tribe has six genera.〔, p. 101〕 Members of the Hylocereeae have leafless (or apparently leafless) flattened stems which act as the plant's photosynthetic organs. Relatively large flowers are borne on the sides of the stems; in many species they open at night.〔 The plants known as "epiphyllum hybrids" or "epiphyllums", widely grown for their flowers, are hybrids of species within this tribe, particularly ''Disocactus'', ''Pseudorhipsalis'' and ''Selenicereus'', less often ''Epiphyllum'', in spite of the common name. ==Genera== The International Cactaceae Systematics Group classification recognizes six genera within the tribe:〔 * ''Disocactus'' Lindl. – includes ''Aporocactus'', ''Nopalxochia'' * ''Epiphyllum'' Haw. * ''Hylocereus'' (A.Berger) Britton & Rose * ''Pseudorhipsalis'' Britton & Rose * ''Selenicereus'' (A.Berger) Britton & Rose * ''Weberocereus'' Britton & Rose ''Disocactus'' × ''Epiphyllum'' hybrids have been called ×''Disophyllum'' Innes.〔, cited at 〕 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「Hylocereeae」の詳細全文を読む スポンサード リンク
