Solanum paucissectum (paucissectum means “poorly dissected,” referring to the leaflets) is a wild potato from Peru.  Plants are usually low-lying, sometimes as much as two feet tall.  Flowers white to light blue.  Berries small and ovoid. 

Jarvis (2008) predicts that this species will lose 95% of its present range by 2055 due to climate change, most likely entailing a critical loss of genetic diversity.


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