Abstract

Two Nevada species are described here for the first time: Penstemon tiehmii N. H. Holmgren, which is endemic to Mount Lewis of the Shoshone Range in Lander County; and Penstemon rhizomatosus N. H. Holmgren, which is endemic to the central Schell Creek Range in White Pine County. They both belong to section Saccanthera and are closely related to P. kingii S. Watson, a Great Basin endemic of valley sagebrush habitats. Both new species are talus plants of higher elevations and differ from P. kingii principally in their rhizomatous habit, petiolate leaves, and pubescence of shorter hairs.
