Characteristics

(Small) trees. Indumentum of solitary hairs; (some) scale hairs present in inflorescences. Branchlets terete, more or less straight, pith narrow. Leaves paripinnate, pseudostipules absent; rachis above grooved, not winged. Leaflets opposite to subopposite, elliptic to narrowly elliptic, symmetrical except for the base, not punctate; base attenuate (to cuneate), oblique; margin entire, slightly curved; apex cuspidate, very apex obtuse, not mucronulate; both surfaces smooth, domatia absent below; venation raised to almost flat above, raised below; veins densely reticulate. Inflorescences pseudoterminal or axillary or ramiflorous thyrses, branches with scale-like hairs; cymules 1-7-flowered, dicha-sial. Bracts and bracteoles caducous. Pedicels sparsely hairy, glabrescent. Sepals 5, pet-aloid, connate at base, biseriate. Petals 5; claw very small to absent; scales absent. Disc uninterrupted. Stamens 8; filaments filiform; anthers basifixed, dehiscence latrorse. Ovary 3-locular, one ovule per locule; style pyramidal with three longitudinal stigmatic grooves. Fruits capsular, obovoid, loculicidal, not winged, stipe slender, outside and inside glabrous. Seeds obovoid, covered by an arillode; the latter open at apical end, without basal pseudofunicle.
More
Shrubs or trees, usually monoecious. Branchlets lenticellate. Leaves paripinnate; leaflets opposite or alternate, usually pellucid-dotted, upper surface usually with appressed lepidote glands; petiolulate. Inflorescence axillary or ramiflorous, solitary or clustered, raceme-like or panicle-like; cymules stalked. Flowers small, regular. Calyx deeply 5-lobed, the lobes 2-seriate, or sepals free, imbricate, elliptic or obovate, concave, petaloid, the outer pair smaller, gland-dotted, ciliolate. Petals 5, obovate or elliptic, membranous; scales absent. Disc regular, glabrous. Stamens 6–8; filaments usually hairy. Ovary 3-locular; ovule 1 per locule; style slender, persistent. Fruit globose or obovoid, drying blackish, 3-locular, loculicidally dehiscent; valves drying ± woody, glabrous. Seed ellipsoidal, slightly compressed; aril thinly fleshy, oily, oblique, ventrally attached to seed and usually covering it.
