Leaves to 70 cm, paripinnate to pseudogemmulate, in terminal bunches; petiole 7–15 cm, glabrous to pubescent. Leaflets 6–28 by 2.5–10.5 cm, narrowly oblong to oblong-or elliptic-lanceolate, opposite to subopposite, often maturing all together, thinly coriaceous, often conspicuously paler abaxially, base ± rounded or rarely subcordate, ± unequal, shortly acuminate, adaxial surface glabrous or with tomentose midrib and pubescent veins, abaxial surface glabrous or with tomentose midrib and pubescent veins, abaxial surface glabrous to softly tawny pubescent, midrib and veins tomentose, costae 9–14 on each side, ± prominent abaxially, tertiary venation often conspicuous; petiolules 3–6 mm. Thyrse to 90 cm, borne in upper axils or supra-axillary, pendent, paniculiform; most proximal branches to 17 cm (10 cm in females), ultimate branchlets cymules of subsessile or shortly pedicellate fragrant flowers; axes glabrous to tomentose; bracteoles minute. Calyx 2.5–3 mm, cupular to shortly tubular, puberulous, margin subentire to minutely, irregularly toothed. Petals 4, 5–10 mm long, subspathulate-elliptic, glabrous to glabrescent. Staminal tube 5–7(–8) mm, glabrescent or minutely pubescent near mouth without, pubescent, tomentellous or very rarely villous within, margin with (5–)6–8 linear-triangular lobes a little shorter than anthers; anthers (5) 6 or 7 (8), basiflxed, glabrous, locellate. Disk absent or very short, fleshy, glabrous, ± lobed. Ovary pubescent; style glabrous to densely short pubescent; stylehead cylindric to clavate. Capsule to 5 cm long, 4.5 cm diam., subglobose, stipitate, glabrous to tomentose (especially when unripe), 2-locular; stipe to 2 cm. Seeds 2, 5–11 mm long, to 8 mm wide, scutiform, half covered by an aril.
