|discussion=<p><i>Diplacus deschutesensis</i> is endemic to Crook, Deschutes, Jefferson, Klamath, Lake, and Wheeler counties of central Oregon. D. M. Thompson (2005) regarded these plants as a zone of stabilized hybrids, intermediate between <i>Mimulus</i> cusickii and typical M. nanus, the range just outside and west of the wider range of typical M. cusickii. In an earlier study that included both of the latter species, W. L. Ezell (1971, and by annotation in 1987) identified the same set of plants simply as M. cusickii, not associating them at all with M. nanus. A. L. Grant (1924, and by annotation of MO collections) identified them variously as either M. cusickii or M. ovatus. Thompson did not say what features of intermediacy he observed in the putative hybrids, but he did note that they produced leaves with acuminate-cuspidate apices and that they would key to M. cusickii.</p><!--
--><p>Leaves of <i>Diplacus deschutesensis</i> are broad with abruptly and sharply acuminate apices like those of <i>D. cusickii</i>, and the corolla coloration also is similar. The flowers (calyx length, corolla tube-throat length, limb width) and capsules of <i>D. deschutesensis</i> are considerably smaller, and the distal leaves are smaller with glabrous surfaces.</p>
