Varieties 4 (4 in the flora). Penstemon deustus comprises four marginally discrete varieties. Extreme forms of each variety are distinctive, but extensive zones of contact exist among the varieties, and populations frequently exhibit degrees of intermediacy, especially in Oregon where all four varieties occur. The Paiute and Shoshoni tribes, centered in the Great Basin, used Penstemon deustus to treat dermatological, gastrointestinal, immunological, and other disorders (D. E. Moerman 1998).

Penstemon seorsus is known from the southern Columbia Plateau and northwestern Great Basin. The species has been documented in Adams, Owyhee, and Washington counties, Idaho, and in Baker, Grant, Harney, Jefferson, Malheur, and Wasco counties, Oregon.
