Vigna subterranea

Vigna subterranea (also known by its common names Bambara groundnut, Bambara-bean, Congo goober, earth pea, ground-bean, or hog-peanut) is a member of the family Fabaceae. The plant originated in West Africa. Vigna subterranea ripens its pods underground, much like the peanut (also called a groundnut). They can be eaten fresh or boiled after drying.
