|discussion=<p><i>Penstemon comarrhenus</i> usually is distinguished from <i>P. strictus</i> by its paler blue corollas, more diffuse inflorescences, and more densely lanate anthers. A putative hybrid between <i>P. comarrhenus</i> and <i>P. barbatus </i>var.<i> trichander</i> has been collected in La Plata County, Colorado (R. E. Umber, B. E. Nelson & T. Davis 999b, KANU, RM).</p>
