- The name of this species commemorates Lieut Col. W.H. Emory. F. emoryi exists in two forms. The Emoryi variety distributed throughout the Sinaloa and Sonora states in Mexico and extends along the edge of the United States in Arizona. Across the Gulf of California, in central Baja California, a variant with straight central spines has been named Ferocactus emoryi var. rectispinus.
- The young specimens have a spherical blue-green stem with prominent tubers with spine blocks. There are about 8 radial spines, strong and curved towards the body of the cactus, and a hook-shaped center.
- As the plant matures, the tubers join together forming ribs and the body elongates until it becomes cylindrical. It can reach 2 meters or more in its natural habitat, but this is unlikely to occur in a greenhouse.
- The flowers can be red or yellow.
- This cactus has a gland located in the areola that produces a sticky secretion that, especially in a humid environment, slowly stains the plant. It does not seem to harm the plant although it slowly begins to make it less pleasing to the eye. This secretion is almost impossible to remove once it has clung to the cactus.
