description
The succulent Euphorbia biharamulensis forms shrubs up to 50 centimeters high, which branch out from the base and are spreading . The clearly square branches are 1.5 to 3 centimeters wide and are divided into 1.5 centimeters long, sometimes longer, sections by inverted egg-shaped constrictions. On the edges there are bulky teeth at a distance of 2 centimeters from one another. The thorn shields are elongated or united to form a 1 to 4 millimeter wide horn rim. Thorns 1 to 15 millimeters long are formed. The stipule spines are very small and there are other very small spines on both sides of the inflorescences.
The inflorescence consists of individual cymen standing on a 3 millimeter long stalk , which are transformed into individual cyathia . These are 8 millimeters in diameter and are colored dark red. The elongated nectar glands adjoin each other. The fruits are clearly lobed, dark red and sessile. They are about 4.5 millimeters long and 9 millimeters wide. The spherical seed is smooth and almost 3 millimeters in size.
