The areoles located on them are covered with thick white wool. The needle-like thorns stick out more or less. The two, occasionally four and then crossed, central spines are purple-red and have a reddish base. They have a length of 1 to 2.5 centimeters. The twelve to 16 yellowish brown radial spines are 0.5 to 1.2 centimeters long.

The sulfur-yellow flowers reach lengths of up to 3 centimeters. Your pericarpel and the flower tube are covered with thick white wool, small scales and hair. The scar is dark red or sometimes light yellow. The initially olive-green fruits turn reddish later and are 1.8 to 2.5 centimeters long. They contain cloudy black seeds that are finely tuberous.
