Discussion

Variety bannockense is found in widely scattered sites in southeastern Idaho (Bannock, Bear Lake, Bonneville, Cassia, and Franklin counties), northeastern Nevada (Elko County), northwestern Utah (Box Elder and northern Tooele counties) and southwestern Wyoming (Fremont, Lincoln, Sublette, and Teton counties). In habit it is similar to the more western E. desertorum, and a sharp, morphologic distinction is not always obvious between the two. Geographically the two approach each other in Box Elder County, Utah, and in Elko County, Nevada.
