Varieties 3 (3 in the flora). Eriogonum jamesii is a nectar source for the rare Spalding dotted-blue butterfly (Euphilotes spaldingi). Eriogonum jamesii and E. arcuatum (see below) are considered “life medicines” and used ceremonially by Native Americans (C. Arnold, pers. comm.; A. B. Reagan 1929; P. A. Vestal 1952). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Of conservation concern. Eriogonum coloradense is a high-elevation species closely allied to E. lonchophyllum. It is restricted to the backbone of the central Colorado Rocky Mountains in Chaffee, Gunnison, Park, Pitkin, and Saguache counties. The Colorado wild buckwheat is listed as a “sensitive” species for Colorado. It is occasionally seen in cultivation. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
