Vigna radiata (Mung bean)

Mung beans originate from India and India remains a leading producer of this legume. Most mung beans are olive green in colour but they can also be yellow, brown, or mottled black. They are an excellent source of folic acid and a good source of magnesium, phosphorus and thiamin. Mung beans are an important food in rural areas of southern Africa, where the dry bean seeds are used or the beans themselves are eaten as a vegetable.

Vigna subterranea (Jugo bean, Bambara groundnut, African groundnut)
