Discussion

Variety argenteus is known from the Panamint Mountains in eastern California to southern Canada, western North Dakota, western South Dakota, Colorado, and central New Mexico. It is widespread in the intermountain region in Arizona, southern Idaho, Nevada, eastern Oregon, Utah, and southwestern Wyoming.

Lupinus lemmonii C. P. Smith belongs here since D. Isely (1998) and T. H. Kearney and R. H. Peebles (1960) stated that the only diagnostic character that differentiates this from var. argenteus is its southern location.
