Trees, shrubs or suffrutices. Leaves alternate, 3-foliolate. Panicles terminal, axillary or both.

Male flowers: calyx (4-)5(-6)-partite; petals (4-)5(-6), white, green or yellow; stamens 5; pistillode usually 0. Female flowers: calyx and petals similar to male; staminodes frequently present; ovary usually 1-locular. Styles 3. Fruit a spherical or ovoid and flattened drupe, frequently asymmetrical. Seeds ovoid or reniform, flattened. A common genus in Zimbabwe and by no means always an easy one to name. Species of Rhus with toothed leaflets can easily be confused with species of Allophylus.
