There are 5 to 60 (and more) ribs . The shape and shape of the large, stiff, somewhat flattened, cross-furrowed, yellowish to reddish thorns , which later become blackish, depend on their age. The four somewhat curved central spines are often arranged crosswise and 5 to 10 centimeters long. The lowest central spine is often larger than the rest. The 8 to 10 radial spines are 3 to 4 inches long.
The numerous flowers appear from the yellow parting wool. They reach a diameter of 5 to 7 centimeters. The elongated, yellow fruits that are dry when ripe are covered with scales, wool and hair and have a persistent flower remnant.
