Stamen-filaments flattened and broadened towards the base.
Calyx c. 3–5 mm., long, infundibuliform, lobed to about 1/3-way.
Flowers appearing with the very young leaves, in axillary paniculate cymes up to 4 cm. long or the female inflorescences reduced to 1–2-flowered abbreviated cymes; branches of inflorescence very slender; bracteoles c. 3 mm. long, filamentous, pubescent; pedicels up to 3 mm. long, slender.
Fruit c. 1·2 cm. in diam., globose, somewhat flattened; pseudaril covering about 2/3 of the endocarp and becoming thin above; endocarp c. 1 × 0·75 cm., subcordiform, smooth, both faces moderately convex.
Leaves 3-foliolate or pinnate with the leaflets 2-jugate (rarely 3-jugate); petiole up to 4·5 cm. long, sometimes sparsely pilose, slender and often twisted; terminal leaflet up to 5·8 × 3 cm., obovate to broadly obovate, apex rounded, base gradually cuneate, lateral leaflets up to 4 × 2·5 cm., elliptic, broadly elliptic or obovate, apex obtuse, base cuneate; all leaflets with margins entire or with a few crenations near the apex, glabrous, glaucous; petiolules up to 1 mm. long.
Bush or small tree up to 5 m. tall, usually glabrous except for the bracteoles; bark smooth, peeling in whitish strips, under layer dark green.
Tree, up to 12 m high. Bark usually peeling in large white papery pieces to expose glaucous underlayer. Leaves 3-foliolate or imparipinnate, glaucous, yellowish green or green; terminal leaflets elliptic, broadly elliptic or obovate, 12-65 x 7-30 mm. Fruit subglobose and not beaked. Pseudo-aril with 4 arms. Flowers yellowish green.
Dioecious tree with a single trunk 2-12 m tall, occasionally shrub-like tree with a short trunk; bark peeling in yellowish white papery pieces to expose a blue-green underlayer or peeling in thick brownish discs; young branchlets glabrous, sparsely pilose but rarely pubescent, not spine-tipped. Leaves trifoliolate (then mostly glabrous) or pinnate, 2-4-jugate (then usually sparsely pilose to pubescent, occasionally also with glandular hairs), glaucous, yellowish green or green; petiole 7-50 mm long, usually relatively thin and slender especially in trifoliolate leaves; upper three-quarters of leaflet margin crenate-serrate, lower quarter subentire or entire, occasionally exclusively entire, terminal leaflet elliptic, broadly elliptic or obovate, 12-65 x 7-30 mm; petiolule 1-4(-12) mm long; apex acute or obtuse, base cuneate rarely obtuse, lateral leaflets elliptic to broadly elliptic rarely suborbicular, 6-45 x 4-25 mm, subsessile or sessile, apex acute rarely obtuse, base cuneate or obtuse. Inflorescence: simple or compound dichasial cymes up to 55 mm long, glabrous, sparsely pilose or pubescent. Flowers unisexual, perigynous. Pedicel 4-10 mm long, pedicel, hypanthium and calyx usually glabrous, seldom pilose, occasionally also with glandular hairs. Disc reduced, without distinct lobes, adnate to hypanthium. Stamens 8. Fruit subglobose, ±15 x 13 x 10 mm, glabrous; pseudo-aril cupular with 2 facial lobes of variable length and form covering lower third to three-quarters of putamen; lobe on less convex face of putamen usually longer and larger than other lobe.
