Vigna mungo, black gram, black lentil, mungo bean (not to be confused with the much smaller true black lentil (Lens culinaris)), black matpe bean, is a bean grown in the Indian subcontinent. At one time it was considered to belong to the same species as the mung bean. The product sold as black lentils is usually the whole urad bean, whereas the split bean (the interior being white) is called Minumulu in Telugu, Urad Dal in Hindi, or white lentils.
