Packera flettii
Packera indecora
Packera flettii is known from the Olympic Mountains and near Mt. Rainer in Washington and coastal mountains of Clatsop County, Oregon. It has a chromosome number unique in the genus and is not known to hybridize with other species of Packera.

Packera indecora is found at relatively low elevations in eastern Canada and at middle to subalpine elevations in the western cordillera. It closely resembles P. pauciflora and it is often difficult to identify specimens in the herbarium. Biosystematic studies (J. F. Bain and J. Whitton 1994) have indicated that although they are morphologically similar, P. indecora and P. pauciflora have distinctly different physiologies and should be maintained as distinct taxa.
