Taxonomic CommentsKartesz (1994 and 1999) subsumes all infrataxa of Sanguisorba canadensis in the full species. Cody (1996) describes the distribution of S. canadensis ssp. latifolia as follows: "Amphi-Beringian; extending across southern Alaska and southern Yukon Territory, and south through British Columbia to Oregon and Idaho." FNA (vol.9, 2014) considers S. canadensis ssp. latifolia as a separate species (= S. stipulata) from S. canadensis.
