[Wikipedia] Limited Range, Serpentine Endemic: Layia discoidea is a local serpentine endemic where it is known only from the Diablo Range in southern San Benito County and far western Fresno County. The known distribution of the species is the New Idria serpentine mass (BLM Clear Creek Management Area) and nearby Laguna Mountain, Hepsedam Peak, and Panther Peak serpentine masses. Layia discoidea is regarded as a strict serpentine endemic with several populations known (as of 2017) to occur on greywacke and chert outcrop and talus at the edge of the New Idria Serpentine Mass near Condon Peak, Sampson Peak, and Idria Reservoir.
