Description

This is a large, woody, smooth liana, up to 20 m long. The stem is up to 5 cm in diametre. The yellow wood secretes yellow sap when cut.

The leaves are usually egg-shaped, (10-)12-25 cm x (5.5-) 8-19 cm, leathery texture and 5-veined arising from the same base. The stalk of its leaf is (4-)7-15(-20) cm long, swollen at both ends but no stipules.

This plant bears unisexual flowers.Its inflorescence arises from the axils or borne on the trunk, resembling an indeterminate branched, raceme-like and slender with size of 10-50 cm long. The lateral branches are spike-like. The flowers are unisexual with 3-4 minute outer sepals and 6 larger inner sepals. The petals are absent. The male flower is in spherical cluster of 9-12 anthers, slightly without stalk.. The female flower bears 3 fruits and has a number of abortive stamens but without an imperfect anther.

Its fruit is a slightly laterally compressed drupe, transversely slightly ovoid, 2-3 cm in diametre, yellow, with a club-shaped stalk. The endocarp is woody, covered with a dense mat of radial, elongated, thread-like structure.

The seed is broadly ellipsoidal, with ruminate endosperm and much folded cotyledons.
