中文摘要
櫻井草屬為櫻井草科(Petrosaviaceae)的單屬植物,1941年在台灣曾採集記錄過,在海南島則於1993年由筆者等初次發現。本屬植物原有三種,筆者認為其中P. sinii應納入P. sakuraii中,因此櫻井草屬僅包含兩種,即P. stellaris(馬來西亞)及P. sakuraii(馬來西亞、緬甸、越南、中國、台灣及日本)。櫻井草P. sakuraii為記念初次發現者櫻井半三郎而命名。櫻井草為腐生植物,在親緣關係上與納茜菜科(Nartheciaceae)、水玉簪科(Burmanniaceae)、薯蕷科(Dioscoreaceae)、田代薯科(Taccaceae) 較為接近。 關鍵詞:分佈,櫻井草屬,櫻井草科,分類學。
