Shrubs, trees, or woody vines, evergreen (deciduous in some Crateva), with branched or simple trichomes. Stipules spinelike, small, or absent. Leaves alternate or rarely opposite, simple or compound with 3[-9] leaflets. Inflorescences axillary or superaxillary, racemose, corymbose, subumbellate, or paniculate, 2-10-flowered or 1-flowered in leaf axil. Flowers bisexual or sometimes unisexual, actinomorphic or zygomorphic, often with caducous bracteoles. Sepals 4(-8), in 1 or 2 whorls, equal or not, distinct or basally connate, rarely outer whorl or all sepals connected and forming a cap. Petals (0-)4(-8), alternating with sepals, distinct, with or without a claw. Receptacle flat or tapered, often extended into an androgynophore, with nectar gland. Stamens (4-)6 to ca. 200; filaments on receptacle or androgynophore apex, distinct, inflexed or spiraled in bud; anthers basifixed (dorsifixed in Stixis), 2-celled, introrse, longitudinally dehiscent. Pistil 2(-8)-carpellate; gynophore ± as long as stamens; ovary ovoid and terete (linear and ridged in Borthwickia), 1-loculed, with 2 to several parietal placentae (3-6-loculed with axile placentation in Borthwickia and Stixis); ovules several to many, 2-tegmic; style obsolete or highly reduced, sometimes elongated and slender; stigma capitate or not obvious, rarely 3-branched. Fruit a berry or capsule, globose, ellipsoid, or linear, with tough indehiscent exocarp or valvately dehiscent. Seeds 1 to many per fruit, reniform to polygonal, smooth or with various sculpturing; embryo curved; endosperm small or absent.

About 28 genera and ca. 650 species: worldwide in tropical, subtropical, and a few in temperate regions; four genera and 46 species (10 endemic) in China.
