Triuridaceae is a family of tropical and subtropical flowering plants, including members which lack chlorophyll and are mycotrophic (obtain food by digesting intracellular fungi). The saprophytic lifestyle of these plants has resulted in a loss of xylem vessels and stomata, and a reduction of leaves to scales.〔(【引用サイトリンク】url=http://www.kew.org/science/tropamerica/neotropikey/families/Triuridaceae.htm )〕 The flowers of Triuridaceae have tepals which are fused at the base and contain 10 to many free carpels. ==Systematics== The circumscription of Triuridaceae has been unstable and some taxa may be paraphyletic.〔(【引用サイトリンク】url=http://www.mobot.org/MOBOT/research/APweb/ )〕 Triuridaceae have been allied with Alismataceae (based on the free carpels) but the APG III system (2009) places them among the non-commelinid monocots, in the Order Pandanales. The genus ''Lacandonia'' is sometimes placed in its own family, Lacandoniaceae.〔 Triuridaceae are included in the Kew Royal Botanical Garden World Checklist of Selected Plant Families and were reviewed by H. Maas-van de Kamer and P. Maas-van de Kamer in 2005. In this list, the genera ''Andruris'' and ''Hyalisma'' are subsumed into ''Sciaphila'' and ''Hexuris'' is subsumed into ''Peltophyllum'', but two new genera ''Kupea'' and ''Kihansia'' are included. Both genera were described (and placed in Triuridaceae) in 2003. The included genera are: *''Kihansia'' Cheek *''Kupea'' Cheek & S.A.Williams *''Lacandonia'' E.Martínez & Ramos *''Peltophyllum'' Gardner (syn. ''Hexuris'' Miers) *''Sciaphila'' Blume (syn. ''Hyalisma'' Champion) *''Seychellaria'' Hemsl. *''Soridium'' Miers *''Triuridopsis'' H.Maas & Maas *''Triuris'' Miers However, APG III, following the Vascular Plant Families and Genera database〔(【引用サイトリンク】url=http://data.kew.org/vpfg1992/genlist.html )〕 also housed at Kew Royal Botanical Gardens, recognizes the following genera: *''Andruris'' Schltr. *''Hexuris Miers''(SUS) = Peltophyllum Gardner *''Hyalisma'' Champ. = Sciaphila Blume *''Lacandonia'' E.Martinez & Ramos = Triuris Miers *''Peltophyllum'' Gardner *''Sciaphila'' Blume *''Seychellaria'' Hemsl. *''Soridium'' Miers *''Triuris'' Miers 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「Triuridaceae」の詳細全文を読む スポンサード リンク
