Discussion

Castilleja latifolia is endemic to the central California coast, especially around Monterey Bay. Around Half Moon Bay in San Mateo County, it apparently forms hybrids with C. affinis var. affinis. Records of this species from north of San Francisco and south of Monterey County are referable to other species.
