The generic name was chosen due to the strength of the spines, which grow from a prominent rib structure. The shape can be either globular or starts as globular, but its height grow faster than its diameter. Generally they are solitary, yet some do happily cluster. Mine are not matured so no flowers, however those that do have them in rings near the apex. In wild, the location is from southwestern USA to the west of Mexico.

I am fairly confident this is Ferocactus histrix, which comes from Mexico.

Ferocactus histrix

It is possible this is within the Ferocactus family so I thought I will show it here. This grew from a seed I planted.

Ferocactus ?
