Discussion

Of conservation concern.

Variety formosum is known only from San Clemente Island, Los Angeles County. Extensive sheep grazing and military operations harmed much of the population prior to the 1960s. Reduction of the sheep population and greater concern for the local environment have greatly improved the ecology of the island and prospects for the long-term survival of this species. The variety is cultivated, and established populations occasionally are found on the mainland of southern California.
