Ferocactus

Ferocactus is a genus with about 30 varieties of large barrel cactus with large spines and tiny flowers. Young ferocactus look like a column, but they fill out as they get older. Many have hooked spines.

Some ferocacti host ant colonies that are drawn in by nectar exuded near the top spines.
