Penstemon aridus is known from the Rocky Mountains in eastern Idaho and southwestern and south-central Montana and the Big Horn and northern Absaroka Mountains of Wyoming. The sometimes grasslike basal leaves distinguish P. aridus from P. humilis and P. virens. At lower elevations or in shaded, forest habitats, plants sometimes have broader basal leaves and tend to be much taller than typical plants; the broadly scarious-margined calyx lobes of P. aridus distinguish it from similar species.

Penstemon lyallii is known from the Central, Northern, and Canadian Rocky mountains in southwestern Alberta, southeastern British Columbia, northern Idaho, northwestern Montana, and northeastern Washington. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
