|discussion=<p><i>Piptatherum shoshoneanum</i> is known best from eastern Idaho, where it grows in the canyons of the Middle Fork of the Salmon River and its tributaries. It has also been found 750 km to the southwest in the Belted Range of southwestern <i>Nevada</i>. So far, fieldwork on the intervening mountain ranges has not revealed additional populations. It usually grows in moist crevices of igneous, metamorphic, or sedimentary cliffs and rock walls.</p>
