description
Maihueniopsis domeykoensis forms low cushions. The conical to obovate, slightly humped shoot sections are up to 5 centimeters long. They carry about 40 small areoles , which are present to the base of the shoot sections. The one to three upright, needle-like, straight or slightly curved, yellow-brown to black central spines are white at their base. They are 2 to 5 inches long. Sometimes they are missing at the tips of the shoot sections. The one to three slender, more or less upright radial spines are much shorter than the central spines.
The flowers have a length of up to 8 centimeters. Their bracts are occasionally tipped orange-red. Your pericarpel is covered with unevenly long thorns of up to 1.5 centimeters. The fruits have thorns up to 3 centimeters long along their upper edge.
