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.

Of conservation concern.
Packera franciscana is known only from above timberline in the San Francisco Peaks and is in the Center for Plant Conservation’s National Collection of Endangered Plants. It spreads by extensive rhizomes and is fairly abundant locally.
