description

Maihuenia poeppigii forms cushions up to 10 centimeters high and 2 meters wide. The fleshy taproot is 40 to 80 centimeters long. The club-shaped shoots are segmented and branch near their tip. They are 2 to 6 inches long and have a diameter of 0.8 to 2 inches. Button-like, spur-like short shoots are not available. The numerous green, pointed leaves are linear, straight to slightly curved, 2 to 10 millimeters long and 1 to 2 millimeters thick. The single, stiff central spine is circular in cross section up to the top and is 1 to 2.5 centimeters long. The 2 inconspicuous radial spines (rarely only one or completely missing) are often on the shoot surface and are up to 6 millimeters long.

The terminal flowers are sulfur yellow. The obovate to club-shaped fruits are 5 to 6 centimeters long.

The number of chromosomes is 2n = 22.
