|discussion=<p><i>Chorizanthe obovata</i> is found in the Coast Ranges. The whitish flowers quickly distinguish it from <i>C. palmeri</i> and the other reddish-flowered members of this complex. Immature plants can be confused with <i>C. staticoides</i>; the floral features readily separate the two species.</p>
