It is a small deciduous tree, which can grow up to 7 m (23 ft) tall. It has black, fissured rough bark and also drooping branches.

Later it produces a seed capsule, the grey pods contain 3-8 smooth, bright yellow or brown seeds.[4]
The wood is very hard, heavy and yellow in colour. It can be used for axe-handles, wagon spokes and fencing poles. The tree is also grown in gardens due to the attractive flowers.[4]
