Varieties 2 (2 in the flora). According to N. J. Turner et al. (1980), plants of the narrow-leaved phase (var. angustifolum) were used for colds, tuberculosis, and other lung ailments, and to treat infected cuts and sores (a decoction of roots and stems). V. F. Ray (1933) reported that a decoction of roots of such plants was taken for diarrhea. E. V. Steedman (1930) said that they were taken for stomachaches, used in steambaths to treat aching joints and muscles, and had a role in a purifying ceremony held in sweatlodges. Steedman also indicated that a strong decoction was taken by the Thompson Indians to treat syphilis. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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).
