Discussion

Penstemon carnosus is known from eastern Utah from the Uinta Basin south to the San Rafael Swell, Henry Mountains, Aquarius and Paunsaugunt plateaus, and west to the Wasatch Plateau, documented in Carbon, Emery, Garfield, Kane, Sevier, and Wayne counties. The species is confused most frequently with P. lentus, which occurs to the southeast in the Abajo and La Sal mountains, and P. pachyphyllus, which occurs to the immediate north and west. Glands on the corollas usually are obscure; they are most easily observed on flower buds.
