The rhomboid to egg-shaped cusps on it are clearly demarcated from each other and are in a few spiral rows. Some of the awkward, persistent leaf rudiments are up to 12 centimeters long. The areoles are located in the upper part of the cusps. From them arise one to four upright, strong, straight, grayish white thorns that are up to eight centimeters long.
