|discussion=<p><i>Chorizanthe membranacea</i> has long been considered an isolated element among the spineflowers. The strict, upright habit, numerous basal and cauline leaves, and broad, continuous, membranous margins of the involucre all reflect that isolation. Pink spineflower is widespread and often locally common in the Coast Ranges of southwestern Oregon and California and on the western foothills of the Sierra <i>Nevada</i> southward to the Transverse Ranges and the Tehachapi Mountains of Ventura and Kern counties, California.</p>
