Ricinocarpus (wedding bush; family Euphorbiaceae) A genus of erect, monoecious shrubs with opposite or alternate leaves which are often linear and revolute (curved back), without stipules. The flowers are unisexual, but occur in clusters, each of which may comprise both male and female flowers which are held on individual stems. The calyx is fused and lobed; there are 4–6 white petals. The male flowers have a column of numerous stamens fused at the base. The female flowers have a trilocular ovary. The fruit is a capsule. The genus is endemic (see ENDEMISM) to Australia, except for 1 of the 15 species, which is found in New Caledonia.
