|discussion=<p><i>Diplacus cusickii</i> is endemic to northern Malheur County, Oregon, and along the Snake River in Ada and Owyhee counties, Idaho. Its narrow geographic range reflects the segregation of the more widely distributed <i>D. cusickioides</i>.</p><!--
--><p>D. M. Thompson (2005) noted that collections in northern Malheur County, Oregon, were intermediate between <i>Mimulus</i> cusickii and M. nanus; the type of M. cusickii is from this area and is among the narrowly endemic, supposedly putative intermediates (G. L. Nesom 2013c). These plants have abruptly and sharply acuminate leaf apices like the more widespread form traditionally identified as <i>Diplacus cusickii</i>; they differ in having glabrous leaf surfaces. Typical <i>D. nanus</i> occurs in close sympatry, without intergradation, with the populations in northern Malheur County. Because of their distinctive morphology and coherent geography, the northern Malheur County plants are reasonably recognized as a distinct species. The more widely distributed form formerly identified as <i>D. cusickii</i> now is identified as <i>D. cusickioides</i>. Populations of <i>D. cusickii</i> in the narrow sense along the Snake River in Ada and Owyhee counties, Idaho, may have dispersed there from the Oregon center. Some plants of <i>D. cusickioides</i> in the Leslie Gulch area of east-central Malheur County have somewhat reduced vestiture, approaching that of <i>D. cusickii</i>.</p>
