Growth
It is a large evergreen tree growing to 40 metres (130 ft) tall, though commonly much smaller. The leaves are 15 centimetres (5.9 in) long and 6–7 centimetres (2.4–2.8 in) broad, pinnate, with 11-15 leaflets. The flowers are bicoloured red and yellow, 3–4 centimetres (1.2–1.6 in) long, produced in racemes 6 centimetres (2.4 in) long. The fruit is a cylindrical pod 12–20 centimetres (4.7–7.9 in) long and 4–6 centimetres (1.6–2.4 in) diameter, the interior divided by a spongy substance into one to five cells, each of which contains a large chestnut-like seed.
Uses
The seeds are poisonous, but become edible when carefully prepared by roasting, cutting up into small pieces, leaching with running water for several days, and pounding into flour. The timber, which somewhat resembles walnut, is soft, fine-grained, and takes a good polish, and the hardwood is very durable.
