The first spherical, later club to cylindrical shaped, dark green shoots are up to 15 centimeters high and reach a diameter of 6 to 8 centimeters. The laterally compressed warts are cylindrical to conical in shape. The axillae are covered with thick white wool in the area that forms the flowers. Central spines are often missing or there is only one. 2 to 4 central spines were very rarely seen. If present, they are protruding fine, needle-like to sub-like or curved, dark brown to black and 0.4 to 2 inches long. 15 to 30 glassy white radial spines are 2.5 to 3.5 millimeters long.
