|discussion=<p>G. J. Goodman (1934) referred <i>Chorizanthe spinosa</i> to Eriogonella, but <i>C. spinosa</i> and <i>C. membranacea</i>, the type of Eriogonella, are well isolated from one another, and both are well removed from the remainder of the annual spineflowers. The Mojave spineflower is local and uncommon from southeastern Kern and southern Inyo counties, south into adjacent northeastern Los Angeles and northwestern San Bernardino counties to Antelope and Lucerne valleys.</p>
