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 Desmodium

Herbs, undershrubs or shrubs , prostrate to erect . Leaf 1-5-foliolate, leaflets petiolulate , stipels 1 in lateral and 2 in terminal leaflet; stipules free or united , striate and ciliate . Inflorescence terminal or axillary , raceme or panicle or subumbellate. Bract striate and pubescent . Calyx 2-lipped, the upper lobe bifid, the lower 3 toothed or the calyx equally 5-lobed. Corolla exceeding the calyx. Stamens monadelphous or diadelphous , 9+1, anthers uniform . Ovary sessile or stipitate , ovules 2 to many. Fruit sessile or stipitate, transversely jointed , articles variously shaped, glabrous to densely pubescent, hairs straight or hooked .

A genus with about 300-350 species distributed in tropical and temperate areas of the world except Europe, New Zealand."Desmodium". in Flora of Pakistan Page 346. Published by Science Press (Beijing) and Missouri Botanical Garden Press. Online at EFloras.org.
