Bergerocactus emoryi (golden cereus, golden-spined cereus, golden snakecactus) is a species of cactus. It is the sole member of the genus Bergerocactus, named after Alwin Berger. The plant is also known as snake cactus.
Bergerocactus is a monotypic columnar cactus genus, and the sole species grows mostly in Baja California, but its range extends northwards to the coast and hills around San Diego; one favored location is Point Loma peninsula. This relatively rare cactus forms colonies of many thin stems, up to 3 feet tall and 2 inches across, with a dense covering of golden spines, of which one is noticeably longer than the rest. Spines towards the base become dark brown with age. The plants branch only if the growing tip becomes damaged. Bergerocactus emoryi is of relatively easy culture, and suited to hanging baskets as well as pots.
