Solanum acroscopicum distribution Map note

Solanum acroscopicum is a Peruvian diploid species.  Plants range mostly 1 to 2 feet tall with long, narrow leaves.  Tubers are long and narrow, reaching as much as three inches in length, but usually much smaller.  This is a high elevation species that typically ranges from about 9800 to 12800 feet.

Vega (1995) found that this species is about as frost tolerant as domesticated potato.
