|discussion=<p><i>Penstemon sudans</i> is known from northeastern California (Lassen, Modoc, and Placer counties); it has been reported for Washoe County, <i>Nevada</i>. D. D. Keck (1940b) observed that some plants of <i>P. deustus</i> from southeastern Oregon (Curry, Jackson, and Josephine counties) approach <i>P. sudans</i> in glandularity, though he considered these to be one extreme of the morphologic spectrum exhibited by <i>P. deustus</i>.</p>
