Packera multilobata
Packera hartiana
Packera multilobata is abundant and widespread west of the Continental Divide. Both morphology and habitat vary. In colder parts of its range, plants are shorter, caudices are better developed with clustered stems, and leaf lobes are larger. In desert-like habitats, basal leaves are narrower and more finely lobed, the tomentum is often persistent, and stems are usually single.

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.
