Packera bolanderi
Packera spellenbergii
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 spellenbergii is known only from Harding and Union counties, New Mexico, and Kane County, Utah. The plants are succulent, have deeply cyanic herbage, and conspicuously revolute leaves.
