Discussion

Of conservation concern.

Subspecies insularis grows only on Santa Catalina and San Nicolas islands and on the mainland on sea bluffs at the south base of San Pedro Hill—a former island now connected by the alluvial Los Angeles Plain but related to Santa Catalina and San Clemente islands directly to the south (W. S. T. Smith 1900).
