Shrubs (root-suckering or not), usually strongly erect, usually with a conspicuous indumentum of stellate hairs on most parts of the plant except the upper surface of the mature leaf. Leaves simple, entire or occasionally with basal lobes, petiolate to occasionally subsessile; stipules absent; upper surface more or less glabrous when mature, smooth or asperate; undersurface with a dense even indumentum; margin flat to revolute. Inflorescence of stalked umbels arranged in often conspicuous terminal panicles, often with 3 or 4 orders of branching, often leaf-interrupted near base. Flowers subtended by filamentous to triangular bracts; calyx minutely 5-toothed; petals 5, outer surface hairy or rarely glabrous, inner surface glabrous; stamens 5, soon falling; styles 2, free, becoming recurved. Fruit a somewhat laterally compressed schizocarp, tardily separating into 2 (rarely winged) mericarps (sometimes one abortive).
