The bristle-like thorns emerging from them are straight, curved or twisted. The one to four central spines are brownish, reddish brown or yellowish and have a length of 0.8 to 4 centimeters. The four to 15 radial spines are whitish to yellowish or brownish and 0.5 to 3 centimeters long.

The usually yellow flowers , only very rarely they are orange-red or red, reach lengths of 5 to 6 centimeters. Your flower tube is covered with brownish wool and bristles. The scars are dark red.
