|discussion=<p><i>Chorizanthe corrugata</i> is found mainly in the Mojave and Sonoran deserts. The narrow, transversely corrugated involucral tube is diagnostic. Some anomalous flowers with four or eight stamens have been seen but this condition was always associated with other flowers bearing the normal number.</p>
