|discussion=<p>Studies of morphology and flavonoids confirm the distinctness of Penstemon subglaber from P. mensarum and P. saxosorum (M. L. Moorman 1982). Penstemon subglaber occurs primarily from the Teton and Wind River mountains of western Wyoming through the Uinta and Wasatch mountains to the Tushar Mountains in south-central Utah.</p>
