Leaves simple, alternate, sometimes distichous, variably ovate to oblong, mostly unlobed, serrate-dentate, rarely entire, 3-5-palminerved, both surfaces covered with stellate hairs, scabrous, petiolate, stipulate; stipules 2, narrow, sharp, entire. Inflorescence peduncled, axillary, oppositifolious or rarely terminal, solitary or clustered, umbellate; flowers hermaphroditic, actinomorphic, small, pedicellate, bracteolate; calyx valvate; sepals 5, free, deciduous, densely hairy without, usually glabrous within; petals 5, free, deciduous, much smaller than sepals, usually glabrous without, glandular at base within; glands surrounded by a tuft or whorl of hairs; gonophore elongated or not, densely pubescent at apex, otherwise glabrous; stamens many, free, inserted on apex of gonophore and around ovary; filaments glabrous; anthers dorsifixed, dorsally curved, 2-thecate, longitudinally dehiscent; ovary superior, ciliate, 2-4-celled, each cell with 1-2(-8)-ovules in 2 rows; style distinct, slim; stigma slightly or deeply 2-4-lobed. Fruit drupaceous, green, glabrous or tomentose, fibrous, entire or mostly 2-4-lobed, the lobes oblate, 1-4-celled; pyrenes 1-4, 1-4-seeded, with spurious partitions between seeds; seeds albuminous. About 70 species distributed over tropical Asia, extending to Africa and Australia, and a few species in eastern Asia, beyond the tropics. Four species found in Taiwan, growing on sunny hillsides.
