Peru (Depts. Arequipa, Ayacucho, Cajamarca and Tacna), on rocky cracks and humid places and in the shade, in rich soils, among herbs or shrubs, 2350-3900 m in elevation.
Solanum acroscopicum is a member of Solanum sect. Petota Dumort., the tuber-bearing cultivated and wild potatoes. On a higher taxonomic level, it is a member of the informally-named Potato Clade, a group of perhaps 200-300 species that also includes the tomato and its wild relatives (Bohs, 2005).
Solanum acroscopicum is morphologically similar to S. trinitense but they mainly differ by the color of the corollas. Solanum acroscopicum has lilac to purple corollas and S. trinitense white corollas.
