Characteristics

Trees or shrubs, usually deciduous. Inflorescence of cymose corymbs or panicles. Flowers 4-merous. Calyx campanulate; lobes absent or short and exposing the corolla in bud, persistent in fruit. Petals red, rarely white. Stamens similar in shape, but the antipetalous ones smaller; anthers linear-subulate; connective elongated below the anther, with 2 anterior appendages at the junction of the filament. Ovary adnate to the calyx-tube by 8 septa, apex convex, usually setose, the bristles sometimes forming a ring. Seeds ± cuneiform, sometimes shortly curved at one end and sometimes (not in E. Africa) ± cochleate at maturity; hilum lateral.
