Elymus glaucus x E. multisetus, squirreltail hybrid, May-August (Elymus hanseni; Sitanion hanseni)

There are several example on and off serpentine. The plants most easy to view is growing just off Trail 9, about 100 yards from Road E, on the north side of Trail b about 50 yards from Road F, and at the beginning of Trail 8 near its intersection with Road D. Elymus glaucus and E. multisetus grow nearby in both locations. This grass was shown by G. L. Stebbins to be a F1 sterile hybrid between Elymus glaucus and, in this case, E. multisetus.
