Discussion

Variety hillii is the small-flowered form that occurs in the Southwest in which the flowers are budlike and scarcely gaping.

(Discussion copyrighted by Flora of North America; reprinted with permission.)

Variety palmeri is widespread over central and northwestern Arizona and adjacent New Mexico, and through high elevations in California, Nevada, Utah, and Washington.

It is similar to variety argenteus except stem pubescence is of mixed long-spreading and short hairs.
