Shrubs or small trees, sometimes spiny. Leaves opposite; stipules often apiculate above. Flowers 4–6-merous, bisexual or sometimes unisexual, in few- to many-flowered cymes or solitary. Calyx with limb-tube short or obsolete, truncate or with triangular or linear lobes. Corolla-tube broadly cylindrical; lobes reflexed, valvate in bud. Ovary 2(–3)-celled; ovule solitary in each cell, pendulous; style with ± globose pollen presenter. Fruit a drupe with 2(–3) stones.
Range
A poorly defined genus with some 50 species in Africa and Asia.

The three Somali species belong to different subgenera, C. glaucum to subgen. Canthium, C. pseudoverticillatum to subgen. Afrocanthium, and C. mombazense to subgen. Bullockia. Subgen.
