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]
