|discussion=<p>Variety ballardii grows in the northeastern Great Plains; it is rare and probably introduced in Colorado, Montana, and northwestern Ontario. In its typical, large-leaved and many-rayed form, <i></i>var.<i> ballardii</i> is quite distinct. It is distinguished by its rounded leaf bases, indument of short hairs, eglandular, and large, many-rayed heads often subtended by one or more large, narrow, leaflike peduncle bracts. Plants of <i></i>var.<i> ballardii</i> are sufficiently similar to those of <i></i>var.<i> foliosa</i> that the two taxa might be treated as convarietal under the name <i></i>var.<i> foliosa</i>. V. L. Harms (2003) treated the Saskatchewan plants as members of a more broadly defined <i></i>var.<i> villosa</i>.</p>
