Discussion

Of conservation concern.

Eriogonum mohavense is typically local and infrequent, and only rarely locally common. It is restricted to the northwestern corner of the Mojave Desert in southeastern Kern, northeastern Los Angeles, and northwestern San Bernardino counties. It occurs also just inside Inyo County. An 1882 C. C. Parry collection (NY) supposedly from San Diego is discounted as to location.
