|discussion=<p><i>Gnaphalium exilifolium</i>, a New World native, differs from the Old World <i>G. uliginosum</i> chiefly in its linear, slightly longer cauline leaves and bracts and in its spiciform arrangement of heads. Pistillate corollas of <i>G. exilifolium</i> are sometimes red-tipped. Cypselae of both taxa are variably smooth to papillate; local populations apparently are consistent in this feature; the variation is otherwise geographically inconsistent.</p>
