Bergerocactus
Bergerocactus emoryi is a species of cactus, known commonly as the golden-spined cereus, golden snake cactus, velvet cactus or golden club cactus. It is a relatively small cactus, but it can form dense thickets or colonies, with the dense yellow spines giving off a velvety appearance when backlit by the sun. From April to May, yellow, green-tinged flowers emerge, which transform into reddish, globular fruit. This species is native to the California Floristic Province, and is found in northwestern Baja California and a small part of California, in San Diego County and on the southern Channel Islands. Where the Mediterranean climate of the California Floristic Province collides with the subtropical Sonoran Desert near El Rosario, hybrids with two other species of cacti are found. It is the sole member of the monotypic genus Bergerocactus.
The plant is near-endemic to Baja California, with the exception of populations on Santa Catalina Island, San Clemente Island, and San Diego, California at elevations from 30 up to approximately 60 meters. The populations remaining in San Diego are disjunct, located in Border Field State Park, Torrey Pines State Park, and Cabrillo National Monument, as the urban development in San Diego has relegated many species to these protected areas.
