A tree. It grows 10 m tall. The leaves have leaflets with one at the end. With the stalk they are 30 cm long. They are hairy towards the base. There are 9-17 leaflets. These are 15 cm long by 6 cm wide. The flowers are white. There are 3-12 in a loose group.
Flowers white, 3–12, in lax to subcapitate compound cymose inflorescences, each part of the inflorescence bearing a simple 3-flowered cyme; peduncle 1–6 cm. long; bracts 1–3 mm. long, subulate, puberulous; pedicels 0·5–1 mm. long.
Filaments about 3·5 mm. long, united for 1/3 – 2/3 of their length, densely hairy towards the apex; anthers 1·5 mm. long, hairy.
The flowers are functionally either male or female and apparently dioecious, but the differences between them are slight.
