Discussion
Camissoniopsis hirtella occurs from Amador and Trinity counties southward in the Coast Ranges and Sierra Nevada of California to the Sierra de Juárez and Sierra San Pedro Mártir, Baja California, usually away from the immediate coast and barely reaching the margins of the desert. P. H. Raven (1969) determined C. hirtella to be self-compatible and primarily autogamous. The species occasionally hybridizes with C. ignota (Raven).
