Solanum hypacrarthrum (hypacrarthrum refers to the position of the articulation at the end of the pedicel) is a Peruvian species.  Plants reach a little more than a foot tall.  White tubers.  Native habitat is hills and brushy forests from 5,900 to 11,200 feet (1800 to 3400 m) (Correll 1962).

All available monographs describe this species as having white corollas, but the single plant that I grew from PI 473477 had a purple flower.  I’m not sure that this accession was correctly identified.

Resistances

Vega (1995) found that this species is less frost tolerant than domesticated potato.
