Trees to 29 m tall, girth to 90 cm; outer bark 0.6–3.8 cm thick and dark grey-brown to blackish; inner bark pink. Leafy twigs pachycaul, (0.6–)0.8–1.5 cm diam., sparsely to densely lenticellate, glabrous. Leaves 38–60 cm long, 4-(or 5-)jugate; petiole 10–22 cm long and 3–7 mm thick, semi-terete with flat to shallowly canaliculate adaxial surface, sparsely lenticellate and glabrous; petiolule 0.5–2.3 cm long and 0.8–2 mm thick, ± terete. Lamina of distal pair leaflet 3.5–6.5 by 13–19.5 cm and basais slightly smaller and terminal slightly larger, all leaflets narrowly oblanceolate or elliptic or oblong, apex acuminate, base cuneate to cuneate-attenuate, subcoriaceous, both surfaces with all veins slightly to conspicuously prominent (in sicco), abaxial surface glabrous to very sparsely pubescent with very short simple trichomes; 9–14 (distal pair leaflets), 10–19 (terminals) and 9–13 (basais) costae on either side of the midrib; glands absent or very sparse and very small. Inflorescences clustered around shoot apex in axils of caducous undeveloped leaves, 16–45 cm long at anthesis, each an open thyrse branched to third order (excl. pedicels) with first order branches up to 15 cm long, pedicels 1–2.5 mm long, all parts densely puberulous. Flowers hermaphrodite, just prior to opening ± cylindrical, 2.6–3.2 mm long, 2.5–3 mm diam., at maximal opening c. 5.2 mm diam. Calyx c. 1.3 mm long, lobes c. 0.5 mm long. Petals c. 4.2 by c. 2.2 mm, imbricate. Androecium cylindrical to narrowly ampulliform, 2.1–2.4 mm long, 2.2–2.9 mm diam., tubular for c. 1/4 of length, tubular part glabrous on both surfaces, filaments glabrous on outside and pubescent on inside, filament apex bifid with teeth c. 0.1 mm long; anthers c. 0.6 mm long and very short beaked, glabrous except for a short tuft of trichomes from the apex. Disk c. 0.7 mm high, glabrous. Style 1–1.5 mm long, 0.4– 0.5 mm diam. (base) and 0.6–0.7 mm diam. (top), narrowly obconical, glabrous. Stigma c. 0.4 mm high, c. 0.9 mm diam., cylindrical with low-domed top. Fruit a 1-seeded globose (to ovoidal) berry, 1.8–4.2 cm diam., brown when mature in vivo, sparsely puberulous, pericarp to 5 mm thick and coriaceous. Seeds narrowly ellipsoidal, to 2.8 by 1.6 cm, incompletely (?) surrounded by sweet tasting jelly-like aril.
