M. Thulin (1999) Rhamnaceae Flora of Somalia 2: 150-156
Plants shrubs or trees, usually aemed with straight of hooked stipular spines; branches often zig-zag. Leaves alternate, crenate to serrate, usually 3-5-veined from base. Inflorescences axially ry cymes or clusters. Flowers bisexual, 5-merous; intrastaminal discs thickened around the ovaries but free from them; ovaries 2(-4)-celled; styles 2(-4)-lobed. Fruits globose drupes with a single, 2(-4)-celled stone.
Ziziphus includes about 85 species that are widely distributed in tropical and warm temperate regions, mostly in dry areas. Many species, including all those found in Somaliland and Somalia, have edible fruits. Their range has been increased by humans, both deliberately and accidentally. The leaves of species some species, including those found in Somaliland and Somalia, are used for shampoo.
