Juncaginaceae is a family of flowering plants, recognized by most taxonomists for the past few decades. It is also known as the ''Arrowgrass'' family. The APG II system, of 2003 (unchanged from the APG system, of 1998), also recognizes such a family and places it in the order Alismatales, in the clade monocots. The species are found in cold or temperate regions in both the Northern and Southern Hemisphere. ==Description== Juncaginaceae are marsh or aquatic herbs with linear, sheathing basal leaves. The flowers are small and green in erect spikes or racemes. The flower parts come in threes, but the carpels are either 3 or 6, joined to a superior ovary. The fruit is a capsule. Example arrowgrasses ''Triglochin'' include the Marsh Arrowgrass (''Triglochin palustris''), the Sea Arrowgrass (''Triglochin maritima''), and also other species like ''Triglochin trichophora'', ''Triglochin striata'' and ''Triglochin mucronata''. The ''Maundia'' genus was grouped within the Juncaginaceae family by the APG II. The newer APG III version, though, suggests it may be necessary to split ''Maundia'' off into its own family, Maundiaceae.〔 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「Juncaginaceae」の詳細全文を読む スポンサード リンク
