|discussion=<p>The native range of Eriogonum parvifolium is restricted to coastal and near-coastal areas (Los Angeles, Monterey, Orange, San Diego, San Luis Obispo, Santa Barbara, and Ventura counties). The coastal expression (var. parvifolium) has thickened leaf blades (0.5–1.5 × 0.3–0.8 cm) and simple or dichotomous inflorescences of compact clusters of involucres containing white to rose flowers. Highly compact and dense mat-forming plants on rocky bluffs immediately next to the ocean were named var. crassifolium; those with yellow flowers were named var. lucidum. The inland form with thin leaf blades (1.5–3 × 0.3–0.8 cm) and highly-branched, cymose, white-flowered inflorescences is perhaps worthy of continued recognition as var. paynei, although there is no sharp distinction between the extremes. Several expressions of the seacliff wild buckwheat are in cultivation, and unfortunately the California Department of Transportation is using the species in roadside plantings, with the result that it is now established in Santa Clara County. Every effort should be made to halt its introduction beyond its native range.</p><!--
--><p>The species is the food plant for two federally endangered butterflies, the El Segundo dotted-blue (Euphilotes battoides allyni), near Los Angeles, and Smith’s dotted-blue (Euphilotes enoptes smithi), near Monterey.</p>
