|discussion=<p>Packera cymbalaria occurs in three, disjunct regions: western Alaska eastward into western N.W.T. and south into northwestern British Columbia; Newfoundland and the Gaspé Peninsula, Quebec; and Siberia. Considerable morphologic overlap exists between western and eastern populations in North America; western populations have slightly different flavonoid chemistries and chromosome numbers. Western populations are either diploid or tetraploid; eastern populations are hexaploid. The correct name for this species may prove to be Packera heterophylla (Fischer) E. Wiebe, based on Cineraria heterophylla Fischer.</p>
