Discussion
Of conservation concern.
Subspecies agourensis is found in the Santa Monica Mountains; it is considered fairly threatened (California Native Plant Society, http://cnps.web.aplus.net/cgi-bin/inv/inventory.cgi). The various forms of Dudleya cymosa found scattered in the Santa Monica Mountains have so far been sorted out as three subspecies—although here, as usual, they don’t sort neatly, and we are left wondering what will turn up next.
