|discussion=<p><i>Eriogonum thurberi</i> is common to abundant but rarely weedy in northwestern Mexico, southern California (Inyo, Los Angeles, Orange, Riverside, San Bernardino, and San Diego counties), and southern Arizona (Cochise, Gila, Graham, Maricopa, Mohave, Pima, Pinal, Santa Cruz, and Yavapai counties). It just enters New Mexico (Grant County). It and <i>E. thomasii</i> are the annual members of the <i>E. cernuum</i> complex typically found on the Mojave and Sonoran deserts, with <i>E. thurberi</i> extending farther to the east and <i>E. thomasii</i> farther to the north. The two occasionally grow together.</p>
