Discussion

Variety platyphyllidius is dispersed widely from eastern Oregon and northeastern California, across southern Idaho into western Wyoming, northeastern Nevada, and barely into northern Utah and northwestern Colorado. It is apparently common only locally, distinguished by its typically pale flowers and thick-textured fruits (approximate length of two times width or less).

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.
