|discussion=<p><i>Penstemon wilcoxii</i> hybridizes with <i>P. albertinus</i> in areas of sympatry in east-central Idaho and west-central Montana (D. D. Keck 1945; A. Cronquist 1959; D. V. Clark 1971). Putative hybrids and/or introgressants exhibit varying degrees of morphologic intermediacy between the parent species. Many herbarium specimens are difficult to determine with confidence.</p>
