It develops a trunk that can reach up to 1 meter in height, with bluish-green, upright shoots branching out from the base, each approximately 20 centimeters in diameter.

Each shoot features woolly areoles that are about 2.5 centimeters long, from which arise strong, stiff thorns that can be whitish-gray or black at their base and tip.

The areoles capable of flowering are circular and woolly, producing 17 to 45 thorns that can be up to 6 centimeters long, without a clear distinction between central and peripheral types.

The plant also produces spherical, fleshy, red-purple fruits that are ripening, characterized by areoles covered in straw-yellow wool and numerous 3-centimeter-long bristles.
