--><p>Clarkia biloba is most closely related to C. lingulata, which is derived from C. biloba subsp. australis. Some populations of C. biloba subsp. brandegeeae (originally described as a form of C. dudleyana) are morphologically very similar to some individuals of C. dudleyana but the two taxa are separated geographically, have different chromosome numbers, and hybrids between them are sterile.</p>
