Achnatherum parishii subsp. parishii
Achnatherum parishii subsp. parishii grows on dry, rocky slopes, in desert shrub and pinyon-juniper associations, from the coastal ranges of California to northeastern Nevada, eastern Utah, and the Grand Canyon in Arizona. Its range extends into Baja California, Mexico. It differs from A. coronatum in its shorter culms and once-geniculate awns, and from subsp. depauperatum in its longer culms, hairy sheath margins, and sparsely hairy paleas.
