Description:

Shrubs, and rarely subshrubs, bare or hairy, spiny or spineless, branches are round, polygonal or winged. Leaves simple or rarely triple, whole or absent. Stipule small or missing. Multiple flowers or 2 - 5 in the top of head cluster or clusters, rarely single. Bell-shaped calyx, improper deeply bilabial, upper lip with two, bottom with three equal or longer than tube teeth. Corolla yellow, rarely orange-yellow or white, irregular, 5 petals - flag, keel and wings. Stamens 10, fused, 5 with anthers attached to the tubular part, and with 5 anthers attached at the base. Ovary goal or fibrous. Beans oblong, egg-shaped or ovate rhombic, flattened or convex; cross-section narrow to the wide elliptical, with 2 - 8 seeds, goal or fibrous, after ripening rarely cracks or no cracks. Seeds lenticular, smooth, without appendage. Insects pollinating, be propagated by seed and partly by root cuttings.
Economic importance. Coloring, honey, strengthening eroded terrain. A number of species can be grown as an ornamental. Some species are found widely in the high pastures, but the feed value has not been studied. Due to the content of alkaloids in seeds in the fruit are poisonous.

Genista /dʒɛˈnɪstə/[2] is a genus of flowering plants in the legume family Fabaceae, native to open habitats such as moorland and pasture in Europe and western Asia. They include species commonly called broom, though the term may also refer to other genera, including Cytisus and Chamaecytisus. Brooms in other genera are sometimes considered synonymous with Genista: Echinospartum, Retama, Spartium, Stauracanthus, and Ulex.
They are mainly deciduous shrubs and trees, often with brush-like foliage, often spiny to deter grazing, and masses of small, pea-like yellow blooms which are sometimes fragrant.[3] Many of the species have flowers that open explosively when alighted on by an insect, the style flying through the upper seam of the keel and striking the underside of the insect, followed by a shower of pollen that coats the insect.[4]
The name of the Plantagenet royal line is derived from this genus, being a corruption of planta genista.[5]
