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 janishiae occurs largely in the Great Basin physiographic region. Populations have been documented in northeastern California (Lassen and Modoc counties), southwestern Idaho (Owyhee County), northern Nevada (Elko, Eureka, Humboldt, Lander, Nye, Washoe, and White Pine counties), and southeastern Oregon (Harney County).
