Packera bolanderi
Packera cana
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 cana is found in a wide variety of habitats and in a wide range of elevations throughout the western Cordillera and into the High Plains. Morphology is relatively uniform throughout its range except that alpine specimens are notably dwarfed and are often mistaken for P. werneriifolia, which differs by its consistently scapiform habit.
