Synonyms: Astragalus parviflorus (Pursh) MacM.; Atelophragma elegans (Hook.) Rydb.
Known Distribution in Maine: There are two documented records for this species in Maine. It is known from a 1945 collection in Ft. Kent, and from a site in Caribou that was first observed in 1939 and last observed in 1941. This site was presumably blasted during the construction of an access road.
