Discussion

Variety higginsii, from Chaves County in New Mexico, and Hudspeth, Hutchinson, and Potter counties in Texas, almost certainly is a derivative of var. diphysus, differing only in its pale flowers.

Variety pohlii is restricted to the Rush and Skull valleys in Tooele County. The shortly stipitate fruit is unusual among varieties of Astragalus lentiginosus.
