Family Fabaceae

The Fabaceae are herbs, vines , shrubs , trees , and lianas found in both temperate and tropical areas. They comprise one of the largest families of flowering plants , numbering 630 genera and 18,000 species. The leaves are stipulate , nearly always alternate, and range from bipinnately or palmately compound to simple . The petiole base is commonly enlarged into a pulvinus that commonly functions in orientation of the leaves (sometimes very responsively, as in the sensitive plant, Mimosa pudica). The flowers are usually bisexual , actinomorphic to zygomorphic, slightly to strongly perigynous, and commonly in racemes , spikes, or heads . The perianth commonly consists of a calyx and corolla of 5 segments each. The androecium consists of commonly 1- many stamens (most commonly 10), distinct or variously united , sometimes some of them reduced to staminodes. The pistil is simple, often stipitate , comprising a single style and stigma, and a superior ovary with one locule containing 2-many marginal ovules. The fruit is usually a legume, sometimes a samara, loment, follicle, indehiscent pod, achene, drupe, or berry. The seeds often have a hard coat with hourglass-shaped cells , and sometimes bear a u-shaped line called a pleurogram. [Carr]

Subfamily Faboideae

Mostly herbs, shrubs , or trees . Leaves pinnate or palmate to trifoliolate or apparently simple . Corolla usually, showy, zygomorphic, the petals imbricate, posterior (upper or banner ) petal outermost in bud. Stamens 10 or 9 + 1 (diadelphous ), not showy. Pollen released in monads . Seeds with u-shaped line (pleurogram) lacking. [Carr]

Genus Vigna

Climbing , prostrate or erect herbs or subshrubs , rarely small shrubs . Leaves pinnately trifoliolate ; stipules bilobed or spurred at the base or not spurred, stipels generally present. Inflorescence axillary or terminal , falsely racemose or flowers in dense 1-many flowered subumbellate clusters ; rachis usually thickened and glandular at the point of insertion of pedicels; bracts and bracteoles ± deciduous. Calyx 5-lobed, 2-lipped; upper lip of 2 lobes completely or partly united , lower lip 3-lobed. Vexillum with inflexed auricles and 2-4 appendages or rarely appendages absent; keel truncate , obtuse or beaked , sometimes the beak incurved through up to 360°. Stamens diadelphous 9+1, anthers uniform . Ovary 3-many ovuled; style with tenuous lower part obsolete or quite long, filiform or flattened, upper part thickened and cartilaginous , straight or curved , upper portion barbate or hirsute on inner side, sometimes produced beyond the stigma to form a short to long subulate or rarely flattened or capitate beak; stigma completely lateral , oblique or rarely ± terminal. Pod linear or linear oblong, cylindrical or flattened, straight or curved. Seeds mostly reniform or quadrate ; aril obsolete to well developed, often 3-pronged.

A large genus with c. 150 species, throughout the tropics of both hemispheres.[1]
