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 cusickii is fairly common in scattered portions of Deschutes, Harney, Klamath, and Lake counties. It is gradually being introduced into cultivation. Eriogonum prociduum is distinct from E. cusickii, but some populations of the latter in Lake County, Oregon, south of Christmas Valley and northwest of Wagontire, have capitate inflorescences even in fruit. These plants differ from typical E. prociduum by consistently having small, rather narrow leaf blades (3–6 × 1–4 mm) that sheath up the flowering stems.
