Discussion

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).

Varieties 2 (2 in the flora).

Eriogonum panguicense is an isolated species that may be related to the E. batemanii complex, or perhaps to E. lonchophyllum. It is a distinct taxon and worthy of horticultural consideration as a rock garden plant. The large (0.5–0.6 mm), oblong, deep purplish-red anthers against the whitish tepals are striking.
