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.) |
Eriogonum roseum is widespread and typically common; occasionally it will be locally abundant but only rarely can it be considered weedy. It occurs from southwestern Oregon south through much of California to northern Baja California Norte, Mexico. Morphologically this annual species approaches the perennial E. elongatum, and poorly prepared specimens sometimes are difficult to differentiate. A clear distinction between E. roseum and E. gracile appears to be consistently possible in the field, but some herbarium material can be difficult to assign. By and large, E. roseum is more robust and less branched than the decidedly more slender and graceful E. gracile. Seeds of Eriogonum roseum were pounded into a powder and either mixed with water and used as a beverage or eaten raw by the Kawaiisu people (M. L. Zigmond 1981).
