Tristiropsis Radlk.

Trees, monoecious. Indumentum of solitary, simple hairs only. Branches (sub)terete, densely minutely tomentose, glabrescent. Leaves bipinnate or the upper ones at least forked, with several leaflets per branch; neither pseudo-stipules, nor winged; petiole pulvinate, ± flattened above; pinnae alternate, rarely opposite, unequally pinnulate. Leaflets alternate to subopposite, chartaceous, glabrous or variably hairy; base oblique; margin entire; midrib prominent beneath; nerves dense, spreading, reticulations elongated parallel with the nerves, rather lax, prominulous on both surfaces. Inflorescences thyrses, axillary towards the end of the branches; peduncle pulvinate; branches few, spreading, bearing few to many, short-to long-stalked, few-to many-flowered (in the upper parts reduced to 1 flower) cymes; pedicels articulated at base. Flowers fairly big. Sepals 5, free, imbricate, concave, the two outer ones slightly or hardly smaller, fleshy, margin pet doid or not, outside appressedly, densely, shortly tomentose, margin ciliate. Petals 0 or 5, slightly shorter than the sepals, clawed or not, outside mainly towards the base sericeous, margin ciliate; scale single, (somewhat) bifid, hairy, not crested. Disc uninterrupted. Stamens 8(-13), hardly or not exserted; filaments filiform; anthers basifixed, ovate-oblong, cleft at base for a third at most, the apex of the connective usually rounded-apiculate by a gland which is dark when dry, dehiscence latrorse. Pistil densely, appress-edly fulvous-hairy; ovary conical-ovoid, faintly 3(-5)-gonous, 3(-5)-locular, tapering into a short style with a 3-grooved stigma. Ovules 1 per locule. Fruits subdrupaceous, (l-)3(-5)-celled, shortly attenuate to short-stipitate at base, shortly apiculate at apex, densely minutely tomentose, subglabrescent; wall thin, pericarp fibrous, endocarp woody; inside variably hairy. Seeds brown, hilum basal, orbicular; no arillode.
