型態特徵
Shrubs (rarely scandent) or trees, unarmed. Leaves opposite or whorled, digitately 3-foliolate or 1-foliolate. Inflorescences thyrsiform or sometimes reduced to single flowers, axillary or on branchlets below leaves or rarely terminal, ramiflorous, or cauliflorous. Flowers small, bisexual or functionally unisexual; sepals 4; petals 4, distinct, valvate or narrowly imbricate; stamens (rudimentary in female flowers) 8 or 4, distinct; disc intrastaminal, pulvinate to annular or cupular; gynoecium (a rudimentary replica of the functional gynoecium or sometimes obsolete in male flowers) 4-carpellate, the carpels connate basally or up to their full length, with a common apical style or the stylar elements rarely becoming divergent, the stigma punctiform to capitate, peltate, or 4-branched, the ovules 2 or sometimes 1 per carpel. Fruit of 1–4 basally connate follicles (the abortive carpels, if any, persistent) or grading to syncarpous (carpels united into a 4-locular, loculicidally dehiscent capsule). Seeds solitary or in pairs, remaining attached in dehisced fruit; testa with thick inner layer of dense, black sclerenchyma and spongy outer layer bounded externally by a shiny, black pellicle.
