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.
