|discussion=<p><i>Penstemon superbus</i> is known from Cochise, Gila, Graham, Greenlee, and Pima counties, Arizona, Grant and Hidalgo counties, New Mexico, and in adjacent Chihuahua and Sonora, Mexico. The species resembles <i>P. parryi</i>; it differs by broader leaves and corollas that are orangish pink to red, more nearly radially symmetric, and without white hairs abaxially in the throats. <i>Penstemon superbus</i> also resembles <i>P. alamosensis</i>, which is known from New Mexico and Texas to the east of <i>P. superbus</i>. The glabrous staminode of <i>P. alamosensis</i> distinguishes it from <i>P. superbus</i>.</p>
