Solanum clarum (clarum probably means “clear” or “bright” but the context isn’t obvious) is a species primarily of northwest Guatemala, reaching slightly into Mexico.  Plants roughly one half to one foot tall.  Leaves are simple, unusual for a potato. Tubers smaller than an inch in diameter and white to bluish.  Grows in colonies as an understory plant about 10,200 to 12,500 (3100 to 3800 m) (Correll 1962).

Resistances

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