The succulent Euphorbia carteriana forms shrubs up to 4 meters high with a spreading growth. The triangular branches are up to 3.5 centimeters thick and are clearly winged. The shoots are divided into up to 20 centimeters long sections by less pronounced constrictions. On the edges there are bulky teeth at a distance of up to 4 centimeters from one another. The thorn shields are fused together and form a 1 to 2.5 millimeter wide horn rim. There are thorns up to 1.5 centimeters in length and very small stipple spines.
The inflorescence consists of individual cymes that are forked two to six times and stand on stems up to 1 centimeter long. The cyathia reach 8 millimeters in diameter. The elliptical nectar glands are colored yellow and butt against each other. The ovary is surrounded by a three-lobed flower cover. The clearly lobed fruit is 7 millimeters long and 15 millimeters wide. It stands on an upright and 6 millimeter long handle. Nothing is known about the seeds.
