The tree grows to 20 m tall, its bark pale grey and fissured. The leaves are cordate or broadly ovate, up to 15 cm long. The tiny yellowish, almost white flowers of 0.8–1 cm in diameter appear in clusters of 1—3. The stigmata are stellate, and the ovary is strip-hairy. Long hairs and short hairs grow in longitudinal, alternating rows. The young ovary is white haired and becomes rusty upon maturity. The fruit is flattened.[1]
