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.
