The species prefers moist soils, but has a broad natural range, extending from coastal monsoon forest to the arid central deserts where it grows as an ephemeral following favourable rains.〔〔 The species has been eaten as a green vegetable by Aboriginals. European settlers also ate the plant to prevent scurvy, giving rise the common name of scurvy grass. The species is a minor weed in some parts of its natural range. ==References== 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「Commelina ensifolia」の詳細全文を読む スポンサード リンク
