|discussion=<p><i>Penstemon lanceolatus</i> is known from southern Arizona (Cochise, Graham, and Greenlee counties), southern New Mexico (Doña Ana, Grant, Hidalgo, Luna, and Sierra counties), and western Texas (Brewster County).</p><!--
--><p>Crosswhite published <i>Penstemon</i> ramosus as an avowed substitute for the homonym <i>P. pauciflorus</i> Greene, distinguishing P. ramosus from <i>P. lanceolatus</i> by the former’s branched stems and relatively narrower leaves (1 mm wide versus 4–8 mm wide) with revolute margins. He mapped P. ramosus in southeastern Arizona and southwestern New Mexico and <i>P. lanceolatus</i> in western Texas and northern Mexico. Morphologic differences between these taxa are not consistent enough to warrant recognition of P. ramosus (J. L. Anderson et al. 2007).</p>
