Leaves alternate to opposite, compound. Stipules absent. Petioles to 10-15 cm long. Leaves imparipinnate (with terminal leaflet), with 3-13 leaflets per leaf, lateral leaflets opposite. Lateral petiolules sessile to 3 mm long, terminal petiolule sessile to 30 mm long. Leaflet blades ovate to elliptic or obovate, sometimes narrowly so, (2.4-) 3-12 (-15) cm long, (0.8-) 1.5-4.5 cm wide, base cuneate, rounded, or oblique (asymmetric), margins ± entire, leaf apex acuminate, acute or rounded. Both leaf surfaces hairless or densely pubescent with predominantly stellate hairs below and short sparsely hairy on midrib above. Lateral veins about 16-20 pairs. Oil dots visible to naked eye. Compound leaf axis somewhat flattened, margins angular or shortly winged towards the base.
Inflorescences terminal, paniculate. Flowers bisexual, 5-merous, white to cream, sometimes with a few male flowers. Sepals 5, ovate-triangular, 2.2-2.5 mm long, pubescent outside, free or connate at base only. Petals 5, elliptic-oblong, 5-7 mm long, appressed hairy on outer surface except for margins, inner surface with a few papillose hairs in throat. Stamens 5, filaments curved inwards from upper third; carpels 5, fused and clothed in simple hairs.
Cotyledons obdeltoid to reniform, much wider than long, about 10-13 x 17-22 mm. Oil dots visible with a lens. At the tenth leaf stage: leaflet blades ovate, lanceolate or narrowly elliptic, terminal leaflet attenuate at the base, lateral leaflets ± sessile, midrib raised on the upper surface; oil dots numerous, visible to the naked eye; petiole and rhachis of compound leaf winged.
