Abstract:

Rupert Barneby (1964) expressed "doubts of the legality" in adopting " Astragalus tenellus Pursh" (1813) over A. multiflorus (Pursh) A. Gray (1864). His concern was justified since Pursh invalidated his own name when he simultaneously published Ervum multiflorum (the basionym of A. multiflorus) on a different page in the same work and cited " A. tenellus " in synonymy. By the time Astragalus tenellus Pursh ex E. Sheld. (1894) was validly published, it was a later homonym as well as superfluous. Given the status of A. tenellus Bunge (1869), the name of an Old World species in current use, conservation of A. tenellus Pursh ex E. Sheld. is unlikely, and we recommend adoption of A. multiflorus for the North American plant.
