Discussion | In the flora area, Lycium torreyi occurs in Arizona, southeastern California, eastern Nevada (Clark and Lincoln counties), western New Mexico, western Texas, and southern Utah. It can be distinguished from L. andersonii by its densely ciliate-lanate corolla lobes, and the mouth of the corolla is not quite as narrow. Further, L. torreyi usually occurs by streams or canals, with branches more cascading than upright. C. L. Hitchcock (1932) reported the fruits to be juicy and sweet.
