A tree. It grows 15-45 m tall. The trunk can be 80 cm across. The leaves are oval and are rounded at the base. They are simple and alternate and have long leaf stalks. The leaves on young trees have lobes like fingers on a hand. The leaves are oval and 15-25 cm long by 7-12 cm wide. The flowers are in panicles and are small and pale yellow. The fruit are large papery follicles. They form a boat shaped structure with one seed on one end. The wings can be 22 cm long.

An upper canopy tree, growing in undisturbed mixed dipterocarp, (peat)-swamp and sub-montane forests, usually found on hillsides and ridges at elevations up to 1,200 metres.

The dried arillus (layer around the seeds) is soaked in water to give a sweet drink. This is called 'cheng tng'. The flesh of the fruit is soaked in water to obtain a jelly like texture than is then used as a dessert.
