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.

Within the flora area, Lycium ferocissimum is known only from Los Angeles County. It has the potential to become an invasive weed and its import and cultivation are restricted. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
