Tree to 10 m (30 m, Harms); bole to 28 cm diam., but often flowering as a small treelet. Bark smooth to finely cracked, creamish to brown; inner bark creamy yellow to pink with orange-brown streaks; sapwood cream; heartwood redbrown. Apical buds with fist-shaped pubescent young leaves. Leafy twigs to 6 mm diam., lenticellate. Leaves 35–70 cm, imparipinnate, 5–8-jugate, apical leaflets developing tardily; petiole 7–10 cm, 2–4 mm diam., terete to flattened adaxially, swollen at base, lenticellate, glabrous to sparsely pubescent; rachis winged, wings forming ± right-angled triangles, with the right angle proximal to a pair of leaflets and the long side concurrent with rachis to next pair, the short side to 8 mm; apical leaflet 18–24 by 6–9 cm, obovate, apex gradually acuminate, acumen to 1 cm, base acute to cuneate. Leaflets glabrous to ± pubescent, petiolules 1–2 mm; lateral leaflets opposite, the most distal 14–23 by 5–8 cm, more proximal pairs successively smaller, ovate to suborbicular, apices acuminate, bases ± asymmetric, rounded to acute, venation brochidodrome, costae c. 12–14 on each side, arcuate. Inflorescences of coffee-scented (Mabberley) flowers borne on trunk and branches, very short. Calyx 7–8 mm long, campanulate, coriaceous, ± glabrous, closed in bud, margin with five acute teeth. Petals 13–14 mm long, linear-lanceolate, acute, thickened at apices, sericeous abaxially, apparently free from tube, white. Staminal tube white, with 10(?) emarginate appendages; anthers 10 inserted between bases of appendages. Disk short, tubular. Ovary 5-angled, ovoid, hairy, each locule with 2 superposed ovules; style hairy in proximal half. Fruits apparently solitary, pedicellate, to 3 cm diam., dark brown velutinous. Seeds 3 or 4 (?5), plano-convex, ?arillate.
