Solanum oxycarpum distribution Map note

Solanum oxycarpum (oxycarpum meaning “sharp fruit,” presumably referring to the pointed berries) is a central Mexican species, primarily found in cloud forest habitats.  Plants reach six feet tall.  Flowers blue to purple.  Berries long and conical.  Correll (1962) reports that this species does not always form tubers.
