Eriogonum havardii is infrequent in southeastern New Mexico (Chaves, Eddy, Lea, Lincoln, Otero, and Socorro counties) and western Texas (Brewster, Culberson, El Paso, Hudspeth, Pecos, Presidio, Terrell, Val Verde, and Winkler counties). The leaf blades are demarcated by depressed lines along their entire length, appearing as a series of folds. The bright yellow of the flowers is seen only by looking at the adaxial surface of the tepals, the abaxial surface being wholly obscured by dense white hairs. The species is worthy of cultivation.

Eriogonum ostlundii is relatively common in Piute and Sevier counties, and just enters Garfield County. It is similar to E. spathulatum and could be confused with infrequent, glabrous individuals of that species that occur in Beaver County on the western deserts of Utah. The United States Forest Service considers E. ostlundii to be a “sensitive” species. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
