Discussion
Penstemon elegantulus occurs largely in the Hell’s Canyon region of the Snake River in Idaho and Nez Perce counties, Idaho, and Wallowa County, Oregon. A specimen from near Silver City in Owyhee County, Idaho (Hitchcock & Muhlick 22585, WTU), also appears to be this species. Penstemon elegantulus combines morphologic features of P. albertinus and P. humilis; it generally has obscurely serrate leaves as in the former, and retrorsely hairy leaves and stems as in the latter.
