Cochemiea cerralboa

A slender, mostly solitary, cylindrical cactus, formerly placed in Mammillaria, endemic to Isla Cerralvo in the southern Gulf of California. Its home is a hot, frost-free maritime desert with a dry spring and late-summer rains, so give it full sun, warmth, a gritty mix and a dry winter rest.
