|discussion=<p>In the field, <i>Eutrochium fistulosum</i> is the most distinct species of the genus; herbarium specimens do not always document the distinguishing characteristics: heights commonly surpassing 2 m, proximal stem diameters usually 2 cm or greater, stems strongly glaucous (mostly hollow, sometimes distally hollow), leaves commonly 6 or 7 per node, arrays of heads commonly 30 × 22 cm.</p>
