Discussion

Some specimens of var. eatonii from the Schell Creek Mountains in White Pine County, Nevada, have the longer pairs of stamens prominently exserted and stems obscurely puberulent. Records from Lake County, Colorado, Oneida County, Idaho, and Carbon County, Wyoming, probably are based on plants that were seeded along highways or pipelines.
