|discussion=<p><i>Eriogonum acaule</i> is the ultimate reduction in the <i>E. brevicaule</i> complex. The low, matted habit of this rather elegant species makes it attractive to rock garden enthusiasts. In Colorado, the Bureau of Land Management considers it a “sensitive” species; it is known only from Moffat County. It is encountered more frequently in Wyoming, where it is found in Albany, Carbon, Fremont, Lincoln, Natrona, Sublette, Sweetwater, Teton, and Uinta counties. The species is to be expected just south of the Daggett County line in northeastern Utah.</p>
