|discussion=<p>Chorizanthe leptotheca is found in the foothills of the San Bernardino Mountains of San Bernardino County southward along the eastern edge of the Santa Ana Mountains, and through the San Jacinto and Santa Rosa mountains of Riverside County into the mountains of central San Diego County. The species is also found in north-central Baja California.</p><!--
--><p>Ramona spineflower is clearly related to Chorizanthe staticoides, but that species occurs to the west of the range of C. leptotheca and the two are not known to be sympatric.</p>
