description

Maihueniopsis camachoi forms slightly arched cushions up to 50 centimeters in diameter. The egg-shaped, sharply pointed shoot sections are up to 4 centimeters long. The closely spaced, small areoles are present over almost the entire length of the shoot sections. The one to three straight, slender, slightly upwardly directed, white central spines are up to 6 inches long. Some of them are a little flattened. The one or two short, stiff, bristle-like radial spines are usually bent away and somewhat flattened.

The flowers are up to 6 centimeters long. Its pericarpel, which is slightly bristle at the upper edge, is covered with numerous areoles that are close together.

Maihueniopsis camachoi is widespread in the Chilean region of Antofagasta at altitudes of 2000 to 3000 meters on dry gravel plains and slopes.
