Eriogonum elegans is found primarily on the coastal mountains (Fresno, Monterey, San Benito, San Luis Obispo, Santa Barbara, Santa Clara, and Ventura counties). It is more slender and elegant than E. baileyi. It is rather infrequent especially near the coast, but it can be locally common to even abundant on the Inner Coast Ranges.

Eriogonum thomasii is common to abundant and even weedy throughout its range on the Mojave and Sonoran deserts in Arizona, southeastern California, southern Nevada, and southwestern Utah. The distinctive swollen bases of the outer tepals are easy to observe in fruiting material but not always obvious in early anthesis.
