|discussion=<p><i>Chorizanthe douglasii</i> is restricted to the Santa Lucia Mountains and to the San Gabilan and La Panza ranges of west-central California. The species is infrequent but can be locally common. A single collection made in the Santa Cruz Mountains (Rowntree s.n., 16 Jun 1929, CAS) may have been made in Santa Cruz County, but the location is uncertain and no other collection is known from that region.</p>
