Description

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 Astragalus

Herbs, undershrubs or shrubs . Leaf paripinnate or imparipinnate , rarely unifoliolate or digitately trifoliolate ; leaflets entire, stipels absent; stipulate . Inflorescence racemose, spicate umbellate or solitary; peduncles generally axillary . Flowers bracteate ; bracteoles present or absent; pedicellate or sessile, violet or purple to white or pale yellow. Calyx tubular , teeth subequal . Vexillum ovate , obovate , oblong , panduriform or sometimes appendiculate Wing and keel generally with long claws . Stamens diadelphous , vexillary stamen free, rest (9) united , anthers uniform . Ovary sessile or stipitate , glabrous or pubescent ; style straight or incurved , stigma mostly terminal , sometimes penicillate . Fruit sessile or stipitate, 2-valved, unilocular , partly or completely bilocular by an intrusive membrane . Seed often reniform .

Astragalus is one of the biggest Angiospermous genera with about 1600 species widely distributed in the Old and the New World. In Pakistan it is represented by about 135 species.[1]
