Populations of Penstemon griffinii are documented in Chaffee, Conejos, Fremont, Mineral, Park, Rio Grande, and Saguache counties, Colorado, and Rio Arriba and Taos counties, New Mexico. Penstemon griffinii can be confused with narrow-leaved plants of P. degeneri, but the pubescence on the internal abaxial surfaces of the corollas of P. griffinii is consistently golden-lanate and extends from the abaxial limbs 5–8 mm into the throats of the corollas. In P. degeneri, the internal abaxial surfaces of the corollas are white- or yellow-lanate, sometimes sparsely so, and the indument barely extends into the throats of the corollas.
