''Oreocereus'' is a genus of cacti (family Cactaceae), known only from high altitudes of the Andes. Its name means "mountain cereus", formed from the Greek prefix ' (, mountain) and the New Latin ''ラテン語:cereus'', meaning wax or torch. As they are covered with woolly white fuzz (modified spines), a few species in this genus are sometimes known as the old-man cactus,〔University of Vermont, (Indoor Plants )〕 a generic name that also refers to ''Cephalocereus senilis'' or ''Espostoa lanata''. More rarely, the old man of the mountain is also used for some species. ==Synonymy== The following genera have been included in this genus: *''Arequipa'' Britton & Rose *''Arequipiopsis'' Kreuz. & Buining *''Morawetzia'' Backeb. *''Submatucana'' Backeb. 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「Oreocereus」の詳細全文を読む スポンサード リンク
