Matucana intertexta usually grows individually with spherical to broadly cylindrical, green shoots and reaches heights of growth of up to 30 centimeters with a diameter of 7 to 18 centimeters. There are 14 to 25 blunt, flattened tubercles ribs present. The white, straight or slightly curved, protruding to slightly splaying spines darken with age. There are initially up to 20 spines of 0.5 to 1 centimeters in length, which cannot be differentiated into central and radial spines. Later, two to five central spines with a length of 2 to 4 centimeters and ten to 25 radial spines with a length of 0.7 to 2 centimeters are formed.
