BROOM, known botanically as Cytisus, or Sarothamnus, scoparius, a member of the natural order Leguminosae, a shrub found on heaths and commons in the British Isles, and also in Europe (except the north) and temperate Asia. The leaves are small, and the function of carbon-assimilating is shared by the green stems. The bright yellow flowers scatter their pollen by an explosive mechanism; the weight of a bee alighting on the flower causes the keel to split and the pollen to be shot out on to the insect's body. When ripe the black pods explode with a sudden twisting of the valves and scatter the seeds. The twigs have a bitter and nauseous taste and have long had a popular reputation as a diuretic; the seeds have similar properties. " Butcher's broom," a very different plant, known botanically as Ruscus aculeatus, is a member of the natural order Liliaceae. It is a small evergreen shrub found in copses and woods, but rare Cytisus scoparius, Common Broom. 1. Two-lipped calyx. 5. Monadelphous stamens. 2. Broadly ovate vexillum or 6.
