Description

Solanum clarum distribution Map note

Solanum clarum (clarum probably means “clear” or “bright” but the context isn’t obvious) is a species primarily of northwest Guatemala, where it forms dense colonies in pine and fir forests, reaching slightly into Mexico.  Plants roughly one half to one foot tall.  Leaves are simple, unusual for a potato. 

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