|discussion=<p><i>Penstemon yampaënsis</i> is known from Moffat County, Colorado, Daggett and Uintah counties, Utah, and Sweetwater County, Wyoming. The species appears to be closely related to <i>P. acaulis</i>. Seed release appears to occur as the walls of the capsules deteriorate, rather than through an apical opening as in other <i>Penstemon</i> species. This type of dehiscence also occurs in <i>P. acaulis</i>.</p>
