Solanum scabrum Miller has been reported almost exclusively from cultivation as a vegetable for human consumption. However, molecular and morphological data indicate that a wild taxon exists in Uganda. This wild taxon was previously identified as the poisonous S. nigrum L., but local people use its leaves as food. This taxon is here described as a new subspecies, S. scabrum Miller subsp. laevis Olet. Morphological descriptions and a key to separate the two subspecies of S. scabrum are given.
