Trees, dioecious. Indumentum consisting of simple and stellately bundled, tomentose to hirsute hairs, latter deciduous. Stipules falcate, early caducous, tomentose. Leaves simple, distichous; petiole not to completely slightly pulvinate, below with transverse grooves when dry; blade symmetric (to slightly asymmetric), coriaceous, punctate, base emarginate to attenuate, margin entire, apex acuminate to caudate, very apex obtuse, both surfaces smooth, lower surface variously hirsute to glabrous; venation pinnate, at most slightly raised above, distinct below, nerves looped and joined at the margin, tertiary nerves slightly scalariform, veinlets reticulate. Inflorescences dense axillary clusters of 2-many flowers (reduced thyrses), tomentose, brachyblasts increasing in size with age; bracts on brachyblasts minute, triangular, hirsute. Flowers actinomorphic; pedicels with abscission zone, tomentose; sepals 5, imbricate, succulent, margin entire, apex (emarginate to) acute, outside keeled, tomentose, inside subglabrous; petals 5, valvate, more or less clawed, margin entire, apex emarginate to rounded, especially inside long hirsute; disc annular, consisting of 5 lobes, obovate to square, more or less triangular in transverse section, thick, glabrous, orange. Staminate flowers: stamens with a hirsute androphore from which the filaments branch in two bundles, a lower with 5 anthers and an upper with 3, anthers basidorsally fixed, opening latero-extrorse with a slit, connective hirsute outside, apically often elongated into an appendix; pistillode 3-lobed, between upper stamens. Pistillate flowers: ovary (seldom 2-)3-locular, tomentose; ovules one per locule, descending, epitropous, anatropous, attached halfway to column; style 1, short, hirsute; stigmas 3, deeply divided, above with dendritic papillae, on lower surface hirsute. Fruits globose rhegmas, outside densely tomentose, reticulately wrinkled when dry, with 6 raised lines, dehiscing completely septicidally and partly loculicidally into 3 bifid pieces; inside smooth, glabrous; wall thin, woody. Seeds ovoid, flattened, 1-3 per fruit, black, glossy, abaxially covered up to ⅔ rd by a thin, sometimes lobed aril, lobes sometimes touching adaxially; hilum V-shaped. Embryo ovoid, flattened, endosperm scanty.
