Eriogonum viridescens is infrequent in the Inner Coast and the Transverse ranges (Fresno, Kern, Kings, Los Angeles, Merced, Monterey, Riverside, San Benito, western San Bernardino, San Luis Obispo, Santa Barbara, and Ventura counties). Unlike those of the more widespread E. maculatum, the outer tepals of E. viridescens are swollen apically, rather than basally. A collection made at Crystal Springs in the Coso Mountains of Inyo County (Coville & Funston 909, DS, US) probably is accurately labeled but the location remains to be confirmed by modern collections.

Varieties 2 (2 in the flora). Eriogonum panguicense is an isolated species that may be related to the E. batemanii complex, or perhaps to E. lonchophyllum. It is a distinct taxon and worthy of horticultural consideration as a rock garden plant. The large (0.5–0.6 mm), oblong, deep purplish-red anthers against the whitish tepals are striking.
