Packera bolanderi
Packera fendleri
Varieties 2 (2 in the flora).
The two varieties of Packera bolanderi have been treated as species. The morphologic characteristics used to distinguish the varieties vary widely within some populations. Presence or absence of multicellular hairs has been used to separate the varieties; that trait is also variable. The morphologic distinction is weak; habitat and elevation records lend support for recognizing two varieties.

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.
