|discussion=<p>Some specimens of <i>Pyrrhopappus</i> from the Panhandle of Texas and from New Mexico are intermediate for traits used here to distinguish <i>P. pauciflorus</i> and <i>P. rothrockii</i>. Some authors (e.g., B. L. Turner and K. J. Kim 1990) have included <i>P. rothrockii</i> within <i>P. pauciflorus</i>.</p>
