Description: Growing into a large evergreen tree, usually about 20 m tall but can grow to 30 m tall. The bole is stout and the crown densely foliaged and rounded.
Bark: rough, grey to dark grey-brown, fissured.
Leaves: pinnately compound with 10 to 18 pairs of leaflets which are narrowly oblong, up to 3 cm long
Flowers: fragrant, golden yellow with red veins, about 3 cm across, arranged in lax, slender terminal racemes.
Pods: pale brown, up to 14 cm long, with an edible, sticky, dark brown, acid pulp around the seeds.
Practical notes: Can be grown from both seeds and cuttings. The tree is not very compatible with other plants.
Uses: The evergreen habit and the extending crown of the tree make it very suitable for a "rest and cultural tree" in many villages. This tree is recommended for soil conservation measures and for use in agroforestry systems. It can also be planted as an ornamental and for shade, and is very suitable as a wind and fire-break. The very hard and durable wood is excellent for poles, timber, boat-building and general construction work. It also makes good firewood and high quality charcoal.
The acid pulpy part of the fruits is used in cooking and for making a cooling, mildly laxative drink. Also eaten fresh or used to make refreshing drinks, jams and confections, for additives to chutney, curries and others.
The seeds are also edible and valuable for human consumption and are commonly sold on local markets in many countries. They are peeled and roasted, or boiled.
Leaves, flowers and fruits provide good animal fodder, but can also be used for various foods A red dye can be obtained from the leaves and a yellow dye from the flowers.
Over-ripe fruits are used to clean and brighten silver, copper and brass, and Indian silversmiths polish their goods with a strong infusion of roots mixed with sea salt.
In traditional medicine the fruits are widely used as a remedy against fever, intestinal diseases and diarrhoea. The pulp is used against malaria and on wounds and haemorrhoids. Powdered seeds are used against dysentery. Pulverised bark ashes are used for colic and digestive disorders.
