Maihueniopsis ovata is a species of plant in the genus Maihueniopsis from the cactus family(Cactaceae). The specific epithet ovata means '(Latin ovatus) rounded like an egg, egg-round'. Spanish common names are "Gatito" and "Perrito".
description
Maihueniopsis ovata forms small, fairly dense cushions of up to 10 centimeters in height and 50 centimeters in diameter. The egg-shaped, sometimes tapered, green shoot sections are up to 3 centimeters long. The approximately 20 areoles per shoot section are present up to the base of the shoot sections. Thorns arise from them only in the upper third of the shoot sections. The showy, straw-yellow glochids are up to 1 centimeter long. The three to eight unequal, stiff thorns are reddish brown and have a length of up to 2 centimeters. The largest of them are subtle to slightly protruding.
The bright yellow (to orange) flowers have a length of up to 4.5 centimeters and a diameter of 5.5 centimeters. Your pericarpel is covered with about 16 areoles, which have bristles on the upper edge. The somewhat cylindrical yellow fruits are 2 to 5 centimeters long and sometimes have a few bristles.
