An evergreen tree. It grows to 20 m tall. The bark can be dark brown or almost black. The leaves are divided into 3-6 pairs of leaflets. Each leaflet is oblong and 10-20 cm long by 2-3 cm wide. When young they hang down and are copper coloured. The flowers are orange and do not have petals. They often arise from branches from the wood. The fruit are on stalks 6-25 cm long. They are flat pods which are 10-20 cm long by 3-5 cm wide. They are leathery with 3-5 compressed seeds.
