Species Plantarum 1: 535 ) in Latin〕〔(Tropicos, ''Stratiotes'' L. )〕 Several specific names have been coined within the genus, but at present only one is recognized: ''Stratiotes aloides'', native to Europe and NW Asia.〔(Kew World Checklist of Selected Plant Families )〕 ;formerly included in genus moved to other genera: ''Enhalus Hydrocleys Ottelia'' # ''Stratiotes acoroides - Enhalus acoroides'' # ''Stratiotes alismoides - Ottelia alismoides'' # ''Stratiotes nymphoides - Hydrocleys nymphoides'' # ''Stratiotes quinquealatus - Ottelia alismoides'' ==Description== The leaves are serrate and very brittle, breaking easily when handled. Reproduction is generally by offsets, which may number 5 or more per plant. In the UK, male plants have rarely if ever been recorded, although some hermaphrodite flowers have been recorded from more southerly locations. Sexual reproduction is not known to occur. A characteristic of the genus is the habit of the plants rising to the surface at flowering time. 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「Stratiotes」の詳細全文を読む スポンサード リンク
