Deciduous shrubs or trees, occasionally scrambling; twigs, leaves, peduncle and sepals usually clothed with stellate hairs. Leaves simple, alternate, distichous, stipulate, petiolate, more or less distinctly toothed, rarely lobed, 3-7-nerved, somewhat coriaceous. Flowers usually bracteate, actinomorphic, bisexual, pentamerous, hypogynous, yellow or orange in pedunculate cymes or umbels, peduncles solitary or fascicled, axillary or leaf-opposed. Sepals 5, free, leathery, valvate, often coloured on the inside, deciduous. Petals 5, free, rarely wanting, mostly shorter than sepals, clawed, claw thick, pitted or glandular near the point of insertion surrounded by a villous rim. Stamens usually indefinite, inserted on the androgynophore; androgynophore short, usually glabrous; filaments of irregular length; anthers globose, dorsifixed; dehiscence longitudinal. Carpels 2-4, syncarpous, ovary superior on top of androgynophore, ovary 2-4-locular, ovules usually 8 (each with 2 or more superposed ovules); style one, subulate with 2-4-lobed stigma or laciniate, sometimes peltate, entire. Fruit a drupe, often lobed, containing 1-4 druplets (or pyrenes) which are 1-2- many seeded, often transversely septate between seeds; endocarp usually bony, mesocarp fibrous. Seeds suberect or horizontal, endospermous, embryo straight.
