Discussion
Of conservation concern.
Subspecies setchellii is known from the Coyote Valley area, Santa Clara County; it is considered seriously threatened (California Native Plant Society, http://cnps.web.aplus.net/cgi-bin/inv/inventory.cgi). Although placed formerly with Dudleya cymosa, it is clearly closer to D. abramsii and especially to subsp. murina, which also grows on serpentine and at about the same elevation but some 200 kilometers to the south. Subspecies setchellii tends to be smaller, with petals unmarked and less sharply acute.
