It is native to the United States, where it is a "regional endemic", occurring in parts of southwestern South Dakota, northeastern Wyoming, southeastern Montana, and Nebraska.〔(''Astragalus barrii''. ) The Nature Conservancy.〕 This mat-forming perennial herb grows only about 4 inches in height. The leaves are each made up of three lance-shaped leaflets. The herbage is coated in white hairs which are dolabriform, or shaped like the head of an ax.〔Ladyman, J. A. R.

The fruit is a legume pod up to 8 millimeters in length.〔 Blooming occurs in late April through mid-June; April flowering generally only occurs in years with light snowfall.〔 This plant occurs on buttes and badlands in the Powder River Basin and surrounding areas. The habitat is generally mixed-grass prairie on limestone, sandstone, shale, or siltstone.〔(''Astragalus barrii''. ) Center for Plant Conservation.〕 It grows alongside other species of ''Astragalus'' including ''A. gilviflorus'', ''A. hyalinus'', ''A. bisulcatus'', ''A. racemosus'', and ''A. spatulatus'', and it must be in flower to be distinguished from other species with three leaflets on each leaf.〔 This plant was first collected in 1900 in Wyoming.
