Solanum hougasii (hougasii, in honor of American botanist Robert W. Hougas) is a species of limited distribution in southwest Mexico.  Plants reach a little over two feet tall.  White flowers.  Round berries.

This species can survive frosts down to 26 degrees F (-3.5 C) (Li 1977).  Vega (1995) found that this species is less frost tolerant than domesticated potato.
