The roots are usually fibrous, sometimes a short taproot is formed. There are 14 to 24 ribs that are deeply notched. The mostly upwardly curved, thin to thick and awlish thorns are horn-colored with a darker tip. They turn gray with age. The four to eight central spines are 2 to 3 centimeters long, the ten to 15 radial spines 1 to 3 centimeters long.

The broad, funnel-shaped flowers appear from young areoles and often form a circle around the apex.

They are 1.1 centimeters long and open with a basal pore.
