Occurs in northern Namibia, Botswana, Transvaal, Swaziland and northern Natal. This is a protected tree and is medium sized growing to 15 m. It is semi deciduous and has grey bark which oozes red when cut. The mauve, sweetpea-like, scented flowers are a good source of nectar and pollen for the bees and they open in summer and are replaced by fruit which consists of a flat pod which hangs from the tree for many months. It is found from the Eastern Cape , KZN, Mpumalanga and Limpopo so is definitely frost tender, although it is drought hardy. It is often an indicator of underground water. The bark has a distinct grey, mottled appearance. The wood is hard, yellowish and is used for furniture, carvings, mealie stumpers and dug out canoes. It burns too fast so is not used for firewood. The leaves are grey-green above and pale grey below. A nymph sucks the sap and a water secretion drips from the tree resulting in its common name of “Rain tree”. The leaves are browsed by giraffe and elephant and browsers eat the fallen leaves at the end of winter so it is useful for a game farm. They are also eaten by humans as spinach in times of need. It is used medicinally as bark infusions treat diarrhea, intestinal problems, colds, snake bite and as a remedy for hookworm. Smoke from a burning root is inhaled to treat a cold. It is said to be a lucky charm and is used to resolve disputes. The roots and bark are highly toxic and are cut into pieces, thrown into water to paralyse fish so it is used as fish poison. The fish float to the surface and are then netted and remain edible. There is a belief that bad luck comes to those who cut down the tree. It is the larval host plant to the Striped Policeman and the Large Blue Emperor butterflies. The name is derived from the Greek Lonche=lance; karpos=fruit; tree with lance shaped fruit; the pod is linear-oglong, flat, membranous or leathery.
