Variety basalticus is confined to western Emery and eastern Sevier counties.

Variety basalticus and Astragalus flexuosus var. diehlii are sympatric in the range of var. basalticus. Fruits of var. basalticus are usually wider and the flowers longer.

Variety sileranus occurs in Lincoln County in Nevada, and Garfield, Iron, Kane, and eastern Washington counties in Utah.

The main overlap in distribution between vars. subcinereus and sileranus occurs in Lincoln County, Nevada, but still, this variety is most closely allied to the disjunct var. basalticus of central Utah.
