Psophocarpus tetragonolobus is a climber grown for its edible plant parts. It has trifoliate leaves, and white or purple flowers. The pods are most distinctive, with four winged edges along the length.
All parts of the plant are said to be edible (Fern, 2019). The leaves, tubers, flowers, seeds and pods are eaten raw or cooked. It is also said to have excellent nitrogen fixing properties, producing much more root nodules than other members in the Fabaceae family.
