Which cactus flower looks like an octopus?

Some think that the flower of the ocotillo [Fouquieria splendens] looks like an octopus. The common names for ocotillo include candlewood, coachwhip, Jacob's staff, and vine cactus. But whether or not the flower looks octopus like, the plant isn't a cactus or succulent. Instead, it's a deciduous shrub that loses its leaves every year, and may grow to about 20 feet/6 meters tall.

The octopus agave [Agave vilmoriniana] and the octopus cactus[Stenocereus alamosensis] are so called, because of their octopus like shapes. They each have branching arms that look like octopus tentacles. The branches grow low to the ground, and out from a central growth point.
