A tree growing from 10 to 15 meters in height or more. It does not have hairs except on the inflorescence.Leaves are suborbicular to broadly ovate, 10 to 20 centimeters long, and entire, with the base broadly cordate. Flowers are 10 to 12 millimeters in diameter, with the petals obovate, are densely hairy without, and are borne on panicles about 15 centimeters long. Fruit, which is somewhat rounded and angled, is 5 to 6 centimeters in diameter; it opens later along the angles. It usually has three cells, each containing a single seed. Seed is somewhat circular, flattened, and rather smooth, but has numerous small ridges. It has a hard, brittle shell about 0.5 millimeter thick. Within this shell is a white, oily, fleshy kernel consisting of a very thin embryo surrounded by a large endosperm. The kernel is covered by a thin, white, paperlike seed coat. |
