|discussion=<p><i>Eurybia divaricata</i> is a mainly Appalachian element of the eastern North American deciduous forest. It is often confused with <i>Eurybia chlorolepis</i> (see W. F. Lamboy 1992 for distinction between the two species), <i>E. schreberi</i>, or <i>Symphyotrichum cordifolium</i>. Lamboy provided a map of the species.</p>
