Discussion

Variety lentiginosus is widespread in the northern part of its range and is partially sympatric with vars. platyphyllidius and salinus in the southern part of its range. It is transitional to both.

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

Variety vitreus is found in the valleys of the upper Virgin River and Kanab Creek, southward to the northern slope of the Kaibab Plateau, and Toroweap and House Rock valleys in eastern Washington and western Kane counties in Utah, and northern Mohave and northwestern Coconino counties in Arizona.
