Ribs: 10-32 according to the size of the plant, low, very broad, sometimes 4 cm. long, separated by wavy intervals, divided into large, low, rounded tubercles.
Areoles: About 2 to 4 cm apart, large, felted when young.
Spines: 8 to 10 on small plants but on old plants often 15 or more, 3-4 cm long, yellowish-brown, reddish or black becoming grey with time which contrast well against the green body at first ascending, afterwards more or less curved outward.
