Discussion
Of conservation concern.
Subspecies insularis is endemic to Santa Rosa Island, where it is known only from near Old Ranch Point and is considered seriously threatened (California Native Plant Society, http://cnps.web.aplus.net/cgi-bin/inv/inventory.cgi). It is remarkable for its small size and for the large number of rosette leaves.
