At maturity, height of the tree will range from 5 to 9 m and have a diameter of 0.5 to 1.5 m. Leaves are compound and are divided into between 4 and 6 pairs of larger (12 by 6cm.) oval shaped leaflets. The leaflets are leathery, long pointed and stalked. The bark is greenish-gray on young trees, changing to a reddish brown with age. On old trees the bark peels off in hard scales.
The flowers which are bright yellow and appear around April and May. They form in large, hanging, pointed bunches and are arranged along a central axis. The seed pod is a long (2 co 3 cm in diameter and 30 or more cm long). Usually smooth, hard and dark brown when ripe; they mature between September and February.
