|discussion=<p>Much confusion has developed over the name <i>Cimicifuga</i> cordifolia Pursh. Although F. Pursh (1814, vol. 2, pp. 372-373) considered it synonymous with <i>C. americana</i>, several other authors have variously misapplied the name <i>C. cordifolia</i> to <i>C. racemosa</i> and <i>C. rubifolia</i>.</p>
