Characteristics

A small deciduous tree. It grows to 6 m tall but occasionally reaches 12 m. It has a rounded crown. The trunk is upright. The bark is grey-brown, smooth and thick. The twigs are sturdy, blunt and wrinkled. The leaves are compound with 3-6 pairs of leaflets and on at the end. The leaf is 11-33 cm long. The leaflets are almost round and with a pointed tip. The side leaflets have an unequal base. The leaflets are usually 2.5-6 cm long and 1.3-4 cm wide. They can be larger. The young leaves are soft, pink and furry. The adult leaves are green on the upper surface and grey underneath. Under the leaf is velvety and with easy to see midrib and veins. The leaves are on long furry stalks. The flowers are greenish-yellow and sweetly scented. They are produced when the tree is without leaves and are crowded on the ends of short branches. Sometimes male and female flowers occur on different trees. The fruit is smooth and round. It is 0.8-1.3 cm long and has short horns on top. The skin is purple-black when ripe. The fruit is edible.
