Red Bead Tree is a timber tree. This plant is found in the wild in India. Leaves are compound bipinnate, green when young, turning yellow when old. The small, yellowish flower grows in dense drooping rat-tail flower heads, almost like cat-tail flower-heads. Fruits are curved, hanging, green pods that turn brown, coil up and split open as they ripen to reveal small bright red seeds.These attractive seeds have been used as beads in jewellery, leis and rosaries. They were also used in ancient India for weighing gold. The seeds are curiously similar in weight. Four seeds make up about one gramme. Children love the hard red seeds and few can resist collecting the brightly coloured seeds usually littered under the tree. The young leaves can be cooked and eaten. the wood is extremely hard and used in boat-building and making furniture.
