Notes: FNA3 does not show this taxon occurring in WA, however the PLANTS database does show a synonymous taxon (Pulsatilla patens ssp. multifida) occurring in WA. Further work needs to be conducted to determine the proper name and taxonomy for the WA entity that we currently call A. patens var. multifida.
