Variety tenuifolia occurs in the Transverse Ranges (Santa Monica, Santa Ynez, San Gabriel, and San Bernardino mountains), south to coastal areas in Orange and San Diego counties, and east to San Bernardino and Riverside counties, and on Santa Catalina Island with var. saxatilis. Single populations grow on San Clemente and San Nicolas islands on mounds of sand brought from the mainland.
