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 Mimosoideae

Mostly trees or shrubs . Leaves mostly bipinnate. Corolla usually not showy, actinomorphic , sympetalous , the lobes valvate . Stamens 10-numerous, often monadelphous , showy. Pollen released in monads , tetrads , or polyads . Seeds with u-shaped line (pleurogram) present. [Carr]

Genus Acacia

Trees , shrubs , rarely herbs, often prickly or spinose . Leaves bipinnate; leaflets small and numerous or leaves reduced to phyllodes; petiolar glands often present; stipules generally spinescent . Inflorescence cylindric spike or globose head ; peduncle solitary axillary or fasciculate or paniculate at the end of branches; bracts often two, scale like, situated on the peduncle at various levels. Flowers small, 3-5-merous, bisexual or plants polygamous. Calyx campanulate , dentate , lobed or polysepalous . Petals usually more or less united , rarely absent. Stamens indefinite, free or shortly and irregularly connate at the base ; anthers small, eglandular . Ovary sessile or stipitate , with 2 or more ovules. Fruit ovate to linear , straight, arcuate or contorted, membranous to woody, rarely articulated or moniliform . Seed large, with a filiform funicle or fleshy aril.

A genus with about 900 species; distributed mainly in tropics and subtropics, especially in Africa and Australia."Acacia". in Flora of Pakistan. Published by Science Press (Beijing) and Missouri Botanical Garden Press. Online at EFloras.org.
