Euphorbia colli culina is a species of the genus spurge ( Euphorbia ) in the family of Euphorbiaceae (Euphorbiaceae).
description
The succulent Euphorbia colliculina forms small shrubs with a bulbous root. A subterranean sprout develops from the root, which merges into an aboveground body with a diameter of up to 15 centimeters. Many branches are formed around the central vegetation center covered with warts, which are spread out upright and up to 25 centimeters in diameter. The individual branches are 3 to 12 inches long and up to 7 millimeters thick. They are patterned by slightly protruding and elongated warts. Leaves up to 1.5 millimeters in length are formed.
The inflorescence consists of individual cyathia that are in clusters at the tips of the branches. They grow up to 5 millimeters in size and stand on stems that are sometimes long-lasting and up to 2 millimeters long. Three to five bracts are formed. The elliptical nectar glands stand individually and are either entire or very small. The bluntly lobed fruit grows to about 7 millimeters and is sessile. It contains the conical seed, which is 4.5 millimeters long and 2.5 millimeters wide.
