Packera bolanderi
Packera cardamine
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 cardamine is uncommon, rarely collected, and known only from the Mogollon Mountains of New Mexico and the White Mountains of Arizona.
