Discussion

Lycium pallidum is known from throughout Arizona and New Mexico, southeastern California, southern Colorado, south-central Nevada (Nye County), western Oklahoma (Cimarron County), western Texas, southern Utah, and northeastern Mexico. Although the fruits of L. pallidum are fleshy, they occasionally have a hardened apex. The range of L. pallidum overlaps with those of several other Lycium species; however, its large, glaucous leaves and long, funnelform flowers are very distinctive.
