The warts stand in rows and are up to 0.3 centimeters long. The 4 to 6 yellow central spines are very similar to the marginal spines or are slightly curved and are 1 to 2 centimeters long. The 15 to 30 marginal spines are yellowish to brownish and 0.8 to 1.5 centimeters long. The flowers are pink to bronze with a dark reddish central stripe or cream flowers on the top of the stem, 1.5–2 cm (0.59–0.79 in) in diameter.[3]
