|discussion=<p><i>Packera hartiana</i> resembles both <i>P. paupercula</i> and <i>P. plattensis</i>; 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.</p>
