Taxonomic Comments
Flora North America vol. 7 (2010) lumps Physaria newberryi var. racemosa into the typical variety and elevates it to a subspecies. Flora North America vol. 7 (2010) also recognizes P. newberryi ssp. yesicola, discovered in 1999, which make up a very few populations at the southwestern most portion of the range of the species.
