Maihuenia patagonica forms cushions up to 40 centimeters high and 3 meters in diameter. The taproot is up to 40 centimeters long. The elongated shoots are not segmented and are loosely arranged. They are up to 40 centimeters long and 1 to 2 centimeters in diameter. There are numerous button-like to cylindrical, spur-like short shoots. The numerous green leaves are conical, egg-shaped or even linear and in cross-section circular to elliptical. They are 2 to 6 millimeters long and 1.5 to 3 millimeters in diameter. The single, stiff central spine is 3 to 7.5 inches long. The 2 radial spines (rarely only one or completely absent) are sometimes inconspicuous, sometimes lie on the shoot surface and are 2 to 8 millimeters long.

The white flowers usually appear terminally on short shoots. The elongated to almost spherical to club-shaped fruits are 2 to 4 centimeters long.

The number of chromosomes is 2n = 22.
