''Xerophyta'' is a plant genus in the family Velloziaceae described as a genus in 1789.〔(Jussieu, Antoine Laurent de. 1789. Antonii Laurentii de Jussieu Genera plantarum :secundum ordines naturales disposita, juxta methodum in Horto regio parisiensi exaratam 50 ) in Latin〕〔(Tropicos, ''Xerophyta'' Juss. )〕 It is native to Africa, Madagascar, and the Arabian Peninsula.〔(Kew World Checklist of Selected Plant Families )〕 Some species in this genus are poikilochlorophyllous plants. This means that during dry climatic conditions, they lose chlorophyll and cease photosynthesis and transpiration. Thus they are extremely tolerant of desiccation .〔Loss of chlorophylls, cessation of photosynthetic CO2 assimilation and respiration in the poikilochlorophyllous plant ''Xerophyta scabrida'' during desiccation. Z. Tuba, H. K. Lichtenthaler, Zs. Csintalan, Z. Nagy1 and K. Szente, Physiologia Plantarum, March 1996, Volume 96, Issue 3, pages 383–388, 〕 Hence the name ''Xerophyta'', from Ancient Greek ξηρός (xeros, "dry") and φυτά (phutá), plural of φυτόν (phutón, “plant”).〔(Wiktionary )〕 ;Species〔 ;formerly included〔 moved to other genera: ''Barbaceniopsis Nanuza Vellozia'' == See also == * Resurrection plant 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「Xerophyta」の詳細全文を読む スポンサード リンク
