Discussion | Within the flora area, Lycium berlandieri occurs in Arizona, New Mexico, and Texas; it has been reported from western Oklahoma (Harmon and Jackson counties). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Populations of Lycium exsertum are morphologically gynodioecious (functionally dioecious), and plants are sexually dimorphic for flower size. Lycium exsertum can be differentiated from L. fremontii by its light purple pendent flowers, often considerably exserted stamens or stigma, and a more upland habitat.
