Penstemon gracilentus
Also called Slender Beardtongue
Penstemon gracilentus is a species of penstemon known by the common name slender penstemon. It is native to the mountains and sagebrush plateau of northeastern California, western Nevada, and eastern Oregon, where it grows in forest, woodland, and scrub habitat. It is a herb producing upright branches to about 65 centimeters in maximum height, the stems developing woody bases. The leaves are up to 10 centimeters in length and linear or lance-shaped. The glandular inflorescence produces several tubular purple flowers up to 2 centimeters long. The mouth of each flower may be hairless or coated in long hairs, and the staminode usually has a coat of yellow hairs.
Slender penstemon is native to three western states, Nevada, Oregon, and California. In California it is found in the northeast in the high Sierra Nevada, the Cascade Range and its foothills, the Modoc Plateau, and the Warner Mountains. In Nevada it is only known from the far western edge of the state in Douglas, Carson City, and Washoe counties. In eastern Oregon it is recorded in four widely separated counties, Jackson, Lake, Wasco, and Baker.
