Solanum alatum

Solanum alatum (syn. Solanum emulans) is a species of flowering plant in the Morelloid clade (the black nightshades) of the genus Solanum, family Solanaceae. It is native to all Canadian provinces (except British Columbia) and nearly all of the United States (except the Pacific coast states and Nevada), and it has been introduced to scattered locales in Europe. There have been considerable taxonomic difficulties associated with this widespread taxon and its relatives Solanum americanum, S. nigrum, and S. villosum.
