Discussion

Variety wahweapensis may be very abundant in wetter years, filling the interspaces in pinyon-juniper woodland much like an alfalfa field. It is found on the plateaus and drainages affluent to Lake Powell in eastern Kane and Garfield counties in Utah, and in northern Arizona. Variety wahweapensis grades into the slender-podded var. palans to the east and the ovoid-fruited var. diphysus southward.

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