Physical 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]

Genus Oxytropis:

Herbs or undershrubs. Leaf imparipinnate, leaflets entire, stipels absent; stipules adnate to the petiole or free. Inflorescence an axillary raceme or spike. Bracts often small. Bracteoles minute or absent. Calyx gamosepalous, teeth sub-equal. Vexillum ovate or oblong. Keel mucronate. Stamens diadelphous, 9+1, vexillary stamen free. Ovary sessile or stipitate, style straight or more often curved, not barbate, stigma terminal. Fruit turgid, the seed bearing suture generally intruded, partly dividing the fruit. Seeds reniform, without strophiole.

About 300 species, distributed in Europe, Asia and N. America; locally represented by 21 species. It is taxonomically a difficult genus; the species are not always clearly definable. On the other hand, lumping of various variants will result in a very heterogeneous assemblage. Experimental work is likely to be useful in understanding the basis of variation.^[1]
