Chorizanthe subg. Amphietes
Species 39 (31 in the flora).
Most species of subg. Amphietes are found in California. Of the others, one is known only from southernmost Peru to central Chile (Chorizanthe commissuralis J. Rémy), while the rest are known only from Baja California, Mexico. Those include C. inequalis S. Stokes, C. turbinata Wiggins, C. mutabilis Brandegee, C. rosulenta Reveal, C. pulchella Brandegee, C. flava Brandegee, and C. interposita Goodman. The latter is the only member of sect. Clastoscapa, the only section of subg. Amphietes not found in our flora.
