Gnaphalium exilifolium, a New World native, differs from the Old World G. uliginosum

       chiefly in its linear, slightly longer cauline leaves and bracts and in its spiciform
       arrangement of heads. Pistillate corollas of G. exilifolium 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
