description
The succulent Euphorbia estevesii forms shrubs that for the most part branch out from the base and can reach a height of up to 1.2 meters. The upright and cylindrical shoots are covered with a thick layer of wax and are 5 to 11 millimeters thick. They are divided into 5 to 10 centimeters long segments. The egg-shaped leaves are at the tip of the shoots and have been turned back. They are up to 42 millimeters long and 12 millimeters wide. The petiole is about 1 millimeter long and the leaves are transient. The stipules are up to 0.9 millimeters long.
Almost sedentary cymen are formed, which stand in axillary clusters. The bracts are deltoid in shape and are up to 1.5 millimeters long and 1 millimeter wide. The cyathia are about 2.5 millimeters long and 3.5 millimeters wide. Five, yellow-green nectar glands are formed, which have white, petal-like appendages. These appendages are about 0.6 millimeters long. The bluntly lobed fruit is about 4 millimeters in size and stands on a stalk that is bent back and up to 6 millimeters long. The egg-shaped seed is up to 2 millimeters long and 1.8 millimeters wide. It has a smooth surface.
