|discussion=<p><i>Eupatorium pilosum</i> has been most commonly treated as a variety of <i>E. rotundifolium</i>; it is distinct morphologically by its leaves, which are narrower and 3-nerved distal to bases, rather than 3-nerved from bases. Distal leaves of <i>E. pilosum</i> tend to differ from the proximal by being alternate with entire margins.</p>
