Discussion

Of conservation concern.

Dudleya variegata is endemic to an area some 80 kilometers long, from near San Diego into northwest Baja California, much of it urban; it is considered fairly threatened in California (California Native Plant Society, http://cnps.web.aplus.net/cgi-bin/inv/inventory.cgi). In Baja California, it hybridizes with D. attenuata subsp. attenuata (R. V. Moran 1951).
