description
Consolea millspaughii grows shrubby with a branched crown and reaches heights of growth of up to 2.5 meters. A trunk of 5 to 7 centimeters in diameter is formed, which is reinforced with numerous, dense and backward-curved tufts of thorns up to 15 centimeters long. The light green, flat, smooth shoot sections are narrowly elongated to obliquely lanceolate. They are up to 40 inches long, up to 10 inches wide and 1 to 1.5 inches thick. The areoles sit in small depressions when the shoots are fully developed. The glochids on it , which can sometimes be missing, are short and yellowish brown. Only on the areoles along the edges of the shoot section are there six to 45 spines , which are initially a little purple. These thorns are shorter than the thorns of the trunk.
The cup-shaped, orange-red to carmine-red flowers have a diameter of up to 1 centimeter. The compressed egg-shaped, up to 2 centimeters long fruits have a diameter of 1.5 centimeters and are only slightly thorny.
