Subspecies

Pelecyphora dasyacantha grows singly and occasionally sprouts. The depressed spherical to short cylindrical shoots reach heights of up to 20 centimeters and diameters of 4 to 7 centimeters. The shoots are covered by the dense white thorns. Of the warts, which are up to 10 millimeters long, the older ones at the base of the shoots are often corked and thornless. The seven to 17 strong, white central spines are 2.5 centimeters long. The 25 to 50 or more marginal spines are strong, white and 0.6 to 2.5 centimeters long.

The flowers are more or less pink to brownish or occasionally greenish. They are up to 2 centimeters long and reach a diameter of 1.5 to 2 centimeters. The flowers rarely open completely due to the dense, stiff spines. The red, club-shaped fruits are up to 10 millimeters long.[2]
