description
The succulent Euphorbia brevitorta arises from a large, tuberous root and grows with dense branches, clumping up to 15 centimeters high and 15 to 100 centimeters in diameter. The triangular branches are up to 12 inches long and 1 to 2.5 inches thick. They are twisted in spirals and have protruding teeth at the edges at a distance of 0.5 to 2 centimeters from one another. The triangular thorn shields are up to 15 millimeters long and 2 millimeters wide. Occasionally they have grown together. Thorns up to 9 millimeters long are formed and there are other, very small thorns on both sides of the inflorescences.
The inflorescence consists of single and simple cymes , which are located on 3 to 5 millimeter long stems. The yellow cyathia grow to a size of 6 millimeters and the elliptical nectar glands collide. The bluntly lobed and sessile fruit is about 8 millimeters in size. It is colored green with a purple coating. The almost spherical seed is almost 3 millimeters in size.
