Deinandra pentactis
Deinandra pentactis occurs in interior valleys and hills of the central South Coast Ranges and in the San Francisco Bay area (near Palo Alto), where presumably introduced. The closely related, morphologically similar, and slightly interfertile D. lobbii replaces D. pentactis in the northern South Coast Ranges.
