Shrubs or small trees. Leaves 1-foliolate; petiole articulate; leaf blade entire at margin. Inflorescences axillary, paniculate to glomerulate-racemose, small; bracts lanceolate, small, soon falling. Flowers bisexual (when protandrous) or unisexual (when plants dioecious), 4-or 5-merous. Sepals 4 or 5, valvate in bud, densely hairy abaxially, persistent but not enlarged after anthesis. Petals 4 or 5, free, imbricate in bud, longer than sepals. Stamens 2 × as many as petals, those opposite sepals well developed, those opposite petals much smaller and staminodal; filaments connate at base into a tube. Carpel 1, somewhat laterally inserted; ovary obliquely ovoid, flattened, hairy; ovules 2, erect, collateral. Style slender, hairy; stigma disk-shaped to 2-lobed, large. Follicle yellowish to brownish when mature, ovoid, tomentose abaxially, slightly to strongly abaxially geniculate, basal part narrowed into a short to long stipe, fertile part dehiscing by a longitudinal slit, with persistent calyx; pericarp woody. Seed 1, ellipsoid, obtuse at both ends; testa mostly black and glossy, basal part covered with a yellowish to orange, thin aril; endosperm ca. 1 mm thick, hard.
Fruit an ovoid, obliquely pyriform or cymbiform follicle, acute at apex, narrowed into a basal stipe, densely hairy externally; dehiscence by ventral suture, seed retained but exposed within pericarp, the latter splitting from apex towards base, pericarp dry and tough at maturity
Flowers with dimorphic androecium and gynoecium
Carpel solitary, ovary and style villous, stigma capitate, ovules inserted on ventral suture
Inflorescences racemose or paniculate, axillary
Shrubs or small trees, with unifoliolate, alternate leaves
Testa of seed dark and shining, aril ± basal, oblique, membranous; endosperm present, forming a thin layer around cotyledons, the latter fleshy, somewhat flattened, radicle apical.
Petals 5, glabrous to pubescent
Stamens 10; 5 episepalous fertile, longer than 5 epipetalous staminodes; all connate into a basal tube, tube hairy internally
