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 putus occurs primarily along the Mogollon Rim in central and east-central Arizona. Populations have been documented in Apache, Coconino, Gila, Navajo, and Yavapai counties. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
