| Notes | Subspecies wrangelica should be re-evaluated. The hexaploid chromosome number reported is more in accordance with the range in the morphologically and ploidally variable Packera heterophylla than with the few diploid counts published for subsp. hyperborealis. However, one chromosome count report is too little to give a clear pattern and support a taxonomy. |
