Packera bolanderi
Packera hartiana
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 hartiana resembles both P. paupercula and P. plattensis; it is separated from both on the basis of geography and morphologic characters. New Mexico populations were formerly treated as P. quaerens; the morphologic characters used to separate the two entities vary and overlap.
