Packera indecora
Packera fendleri
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.

Packera fendleri is abundant, almost weedy in the southern Rocky Mountains. It thrives in a wide range of elevations and in a wide variety of habitats; flowering times vary. It frequently grows in close association with other species of Packera and may hybridize with them.
