Rank ReasonsDiscontinuously dispersed from eastcentral and southeast Nevada to central and southwest Utah and northwest Arizona. There are few collections of this species. However, the plants are inconspicuous, probably often overlooked, and, as the habitat is common across the species' range, it is undoubtedly more common than the number of collections would indicate.
Range Extent CommentsAstragalus pinonis occurs in the western United States, it is most common in east central and southeast Nevada, and also occurs more rarely in southern Utah and northern Arizona (NatureServe Network Database as of May 2021, SEINet 2021).
Occurrences CommentsThere are about 35 occurrences of Astragalus pinonis, most are in Nevada. It is quite rare in both southern Utah and northern Arizona.
