''Disocactus'' is a genus of epiphytic cacti in the tribe Hylocereeae found in Central America, the Caribbean and northern South America.〔 It should not be confused with ''Discocactus'', which is a different genus. Species of ''Disocactus'' grow in tropical regions either on trees as epiphytes or on rocks as lithophytes. They have two distinct growth habits. Species such as ''D. phyllanthoides'' have stems which are round at the base but then become flattened and leaflike. Other species, such as ''D. flagelliformis'' have stems which are round throughout their length.〔 Many of the cultivated plants known as epiphyllum hybrids or just epiphyllums are derived from crosses between species of ''Disocactus'' (rather than ''Epiphyllum'') and other genera in the Hylocereeae.〔, p. 286〕 ==Synonymy== The boundaries of the genera in the tribe Hylocereeae have been subject to considerable change and uncertainty, which is reflected in the number of names which have been used for ''Disocactus'':〔 *''Aporocactus'' Lem. – of which ''Aporocereus'' Fric & Kreuz. is an orthographic variant *''Bonifazia'' Standl. & Steyerm. *''Chiapasia'' Britton & Rose *''Heliocereus'' (A.Berger) Britton & Rose *''Lobeira'' Alexander *''Nopalxochia'' Britton & Rose *''Pseudonopalxochia'' Backeb. *''Wittia'' K.Schum. *''Wittiocactus'' Rauschert ''Pseudorhipsalis'' is sometimes included in ''Disocactus'', although kept separate by the International Cactaceae Systematics Group.〔 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「Disocactus」の詳細全文を読む スポンサード リンク
