Description: Erect or pendent shrubs, the whole plant or at least young parts with a dense indumentum of dendritic or stellate hairs and/or peltate scales; stems much-branched, often dichotomous below inflorescences; branches with 1 pair of prophylls (smaller leaves at base of a shoot) and 1 pair of acute cataphylls at right angles to them near the base.
Leaves petiolate, with curved venation.
Inflorescence terminal, of 1 or more fan-like cymes (cymules) each subtended by a pair of narrow acute bracts; cymules solitary or in determinate or indeterminate conflorescences; flowers in each cymule 3–13, developing centrifugally, the central flower(s) male, lateral flowers female. Male flower 4-merous, with an ovoid to reniform anther opposite each tepal on a short filament; anthers many-locular. Female flower 4-merous; ovary cylindrical to barrel-shaped.
Fruit mostly ellipsoidal, crowned by the persistent tepals.
