Smooth Penstemon (Penstemon subglaber)
Description
This tall penstemon (usually about 0.5 m tall) is common throughout most elevational settings in the sagebrush steppe of this area. It is difficult to distinguish from Penstemon cyaneus, but the anther sacs are less than 2 mm long and little if at all curved or "S" shaped.
