Discussion
Of conservation concern.
Subspecies bettinae can form clumps to 4 dm in diameter. It is known from near the coast west of San Luis Obispo and west of the range of subsp. murina; it is considered fairly endangered (California Native Plant Society, http://cnps.web.aplus.net/cgi-bin/inv/inventory.cgi). R. F. Hoover (1965, 1970) listed as Dudleya parva what seems to be a smaller form of this subspecies, local near San Bernardo Creek and the mouth of Chorro Creek.
