Astragalus aboriginorum

Astragalus aboriginorum is a species of flowering plant in the family Fabaceae. Its name is also spelt Astragalus aboriginum. It is native from subarctic America through Western Canada to the west and central United States, and to Quebec.

Taxonomy
The species was first described by John Richardson in 1823 as Astragalus aboriginorum. In 1827, Sprengel changed the spelling of Richardson's epithet to aboriginum. The genitive plural of the Latin word aborigines is aboriginum, not aboriginorum. Sources differ on whether they consider Sprengel's change justified under the International Code of Nomenclature for algae, fungi, and plants;, Plants of the World Online has aboriginorum, whereas the International Plant Names Index has entries for both Astragalus aboriginum and Astragalus aboriginorum.
