Discussion

Within the flora area, Lycium californicum occurs in southern Arizona and southwestern California. Popula­tions of L. californicum vary in both ploidy (diploid to tetraploid) and sexual system (hermaphroditic to gender dimorphic). Gender dimorphic populations are mor­phologically gynodioecious (functionally dioecious), and plants are sexually dimorphic for flower size, with smaller pistillate flowers.
