Characteristics

Trees, monoecious. Indumentum of solitary simple hairs only. Twigs terete. Leaves paripinnate, 1-6-jugate; neither pseudo-stipules, nor wings; petiolules above slightly grooved, pulvinate. Leaflets opposite to alternate, densely minutely warty beneath, small red glands absent; margin entire (Malesian species). Inflorescences axillary, usually branching, together sometimes pseudoterminal, thyrsoid. Flowers unisexual. Sepals 5, nearly free, valvate to narrowly imbricate in bud, all equal, not petaloid. Petals 5, as long as to distinctly longer than the calyx, hardly to longly clawed; blade with 2 erect or recurved, densely woolly, distinctly crested scales nearly as long as the petal. Disc uninterrupted, erect, thick, ± 5-lobed, glabrous. Stamens 8, in male flowers long exserted; filaments filiform; anthers glabrous, dehiscence latero-introrse. Pistil sessile, densely hairy; ovary 3-locular (Malesian species) with 1 ovule per locule; septa complete; style apical, longer than the ovary; stigma grooved or slightly lobed. Fruits capsular, dehiscence loculicidal, 3-angular-globular, sessile, not winged; outside ± smooth, glabrous or tomentose, inside densely woolly but for a fleshy cupular part around the placenta; pericarp thick, hard-fleshy. Seeds ellipsoid; testa smooth, shiny brownish black; a small sarcotesta with a narrow, free arillode margin at both sides of the nearly basal hilum.
