Trees to 6 m tall. Leafy twigs 6–8 mm thick, glabrous with light brown sparsely lenticellate bark. Leaves 52–80 cm long, 3-jugate; petiole 15–21 cm long, 0.2–0.4 cm thick, semi-terete and flattened adaxially, glabrous to very sparsely puberulous with very short erect trichomes, sparsely lenticellate; petiolule 5–18 mm long, 1–1.5 mm thick, ± terete or slightly flattened adaxially. Lamina of distal pair leaflet 24–30 by 5–8 cm, of terminal leaflet 28–41 by 5.8–10 cm, all leaflets lanceolate with short attenuate base and apex acuminate for (2–)2.5–5 cm long, subcoriaceous, all veins prominent on both surfaces, abaxial surface matt on intervenous lamina and over most of smallest veins and very sparsely pubescent with simple trichomes; 14–17 (distal pair leaflet) and 17–18 (terminal leaflet) costae on either side of the midrib; glands conspicuous. Inflorescences clustered around shoot apex in axils of (sometimes) caducous undeveloped leaves, 7.5–8 cm long at anthesis, a compact thyrse branched up to second order (excluding pedicels) of which the first order branches can be up to 1.3 cm long, all parts densely puberulous and primary rachis sparsely lenticellate. Flowers hermaphrodite, just prior to opening cupiform, c. 2.6 mm long, c. 2.1 mm diam., at maximum opening c. 2.8 mm diam. Calyx c. 1.1 mm long, lobes c. 0.8 mm long. Petals 3.2–3.5 by 1.7– 1.8 mm, imbricate. Androecium cylindrical, c. 2 mm long, c. 1.6 mm diam., tubular for 1/2–3/4 of length, alternate filaments very slightly shorter; filaments (inside and out) sparsely pubescent and tubular part glabrous to very sparsely pubescent, filament apex bifid with erect teeth c. 0.3 mm long; anthers c. 0.8 mm long, apex acute to very shortly beaked, very sparsely and minutely puberulous. Disk c. 0.3 mm high. Style cylindrical, c. 0.5 mm long, c. 0.4 mm diam., glabrous. Stigma capitate, c. 0.7 mm high, c. 1.1 mm diam. at base. Fruit a 1–3-seeded berry, ellipsoidal, 2–3 by 1.7–2.5 cm, green to purplish-brown in vivo, brown in sicco, glabrous, pericarp coriaceous. Seeds ellipsoidal, 1.8–2.3 by c. 1.4 cm, (in vivo) enveloped in a sticky white aril.
