|discussion=<p><i>Eriogonum racemosum</i> is highly variable in stature, the presence of leaflike bracts in the inflorescences, the size and shape of the leaves, and the length of the mature flowers. None of these features is geographically correlated and thus no taxonomic distinctions are attempted. The species is occasionally cultivated. The tomentose, nonfistulose flowering stems easily distinguish it from <i>Eriogonum zionis</i>. Individuals of <i>E. racemosum</i> with glabrous flowering stems are known (Reveal & Holmgren 1893, BRY, US, UTC; Goodrich 17355, BRY; Neese & White 9237, BRY), but are rare and clearly aberrant expressions.</p><!--
--><p>The Navajo or Diné people use the roots of <i>Eriogonum racemosum</i> as a “life medicine,” primarily in the treatment of internal problems, notably poisoning and diarrhea (C. Arnold, pers. comm.; P. A. Vestal 1952). They also use it as an analgesic and orthopedic aid (D. E. Moerman 1986; L. C. Wyman and S. K. Harris 1951); there are reports of its use for venereal disease. Leaves and stems were eaten raw by the Ramah Navajo in northwestern New Mexico (Wyman and Harris).</p><!--
--><p><i>Eriogonum racemosum</i> is the food plant for the Spalding dotted-blue butterfly (Euphilotes spaldingi) and is occasionally visited by the desert green or Comstock’s hairstreak (Callophrys comstocki).</p>
