Description
Solanum lignicaule is a species with a small distribution in southern Peru.
The specific epithet, lignicaule, means “woody stem,” referring to the tendency of the lowest part of the stem to become woody. It is formed from the Latin words “lignum,” for “wood,” and “caulis,” for “stem.” While there is no completely standardized pronunciation for scientific names, the most common way to pronounce this species is probably so-LAY-num lig-nih-KAW-lay.
This species can survive frosts down to 27 degrees F (-3 C) (Li 1977). Vega (1995) found that this species is less frost tolerant than domesticated potato.
