It is a tree up to 50 m tall, with spreading buttresses up to 5 m tall. It has alternate, stalked, compound leaves that are more than 1 m long. Each leaf consists of 4–15 pairs of leaflets, and lacks a terminal leaflet. The papery to leathery leaflets are egg-shaped to drop-shaped, slightly to distinctly sickle-shaped, red when young, dark green above and lighter green below when mature, hairless to covered with hair, 6–40 by 2–13 cm, and with toothed margins. The lowest pair of leaflets is smaller than others, round, ear-shaped or cushion-shaped, 0.4–3 by 0.3–5 cm, appearing like a stipule, and with one of the leaflets reduced. The plant is monoecious, producing both male and female flowers in the same individual. The flowers are about 2–2.5 mm across, generally white to green-yellow, and occur on branched flowering stalks that are 15–70 cm long. Its fleshy fruits have a stony core each. Its fruit is ellipsoid to round, 1.5–5 by 1–3 cm, and red turning black when ripe. The seed is egg-shaped, unequal sided, up to 2.5 by 1.5 cm, brown, and with a white covering (aril).
