Astrophytum Myriostigma Cactus

Echinopsis calochlora grows singly or in groups. The spherical to short cylindrical, dark green shoots reach heights of growth of 6 to 10 centimeters with a diameter of 7 to 9 centimeters. The shoot apex is slightly depressed. There are about 15 sharp-edged ribs up to 1.5 centimeters high that are notched. The circular, gray areoles located on them are up to 1 centimeter apart. Dark grey, needle-like thorns emerge from them, which are thickened at their base. The single, horizontally protruding central spine is 1.5 to 2 centimeters long. The eight to nine slightly unequal radial spines have a length of 0.6 to 1.2 centimeters.
