|discussion=<p>The specific epithet of <i>Euphorbia vallis-mortae</i> is a misnomer because the species does not occur in Death Valley; instead, it is found at the transition of the northern edge of the Mojave Desert and the foothills of the southern Sierra <i>Nevada</i> in Inyo, Kern, and San Bernardino counties.</p>
