:"Vicia heterophylla" ''redirects here, based on the plant described by Carl Presl. The plant thus named by V.N. Voroshilov is ''Vicia japonica'' as described by Asa Gray. ''Vicia sativa'', known as the common vetch, garden vetch, tare or simply "the vetch", is a nitrogen fixing leguminous plant in the family Fabaceae. Although considered a weed when found growing in a cultivated grainfield, this hardy plant is often grown as green manure or livestock fodder. There is no firm evidence that this is the same as the "tare" in some English translations of the Bible (as in the "Parable of the Tares") – ryegrass (''Lolium'') is another candidate. There are at least four subspecies generally accepted: * ''Vicia sativa'' ssp. ''cordata'' (Hoppe) Asch. & Graebn. * ''Vicia sativa'' ssp. ''nigra'' (L.) Ehrh. – Narrow-leaved Vetch (= ssp./var. ''angustifolia'', ssp. ''consobrina'', ssp. ''cordata'' (Hoppe) Batt., ssp. ''cuneata'', ssp. ''heterophylla'', var. ''minor'', var. ''nigra'') * ''Vicia sativa'' ssp. ''sativa'' (= var. ''linearis'', ssp. ''notata'') * ''Vicia sativa'' ssp. ''segetalis'' (Thuill.) Arcang. (sometimes included in ssp. ''nigra'') ==Description== ''Vicia sativa'' is a sprawling annual herb, a member of the pea family Fabaceae, with hollow, four-sided, hairless to sparsely hairy stems which can reach two meters in maximum length. The leaves are stipulate, alternate and compound, each made up of 3 to 8 opposite pairs of linear, lance-shaped, oblong, or wedge-shaped, needle-tipped leaflets up to 3.5 centimeters long. Each compound leaf ends in a branched tendril. The pealike flowers occur in the leaf axils, solitary or in pairs. The flower corolla is 1 to 3 centimeters in length and bright pink-purple in color, more rarely whitish or yellow. The flowers are mostly visited by bumblebees. The fruit is a legume pod up to 6 or 7 centimeters long which is hairy when new and smooth later, brown or black when ripe. It contains 4-12 seeds. 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「Vicia sativa」の詳細全文を読む スポンサード リンク
