Aloe cooperi is a species of aloes in the subfamily of the Affodil family (Asphodeloideae). The specific epithet cooperi honors the English plant collector Thomas Cooper (1815–1913), who worked for William Wilson Saunders (1809–1879) and collected in South Africa.

description

Vegetative characteristics

Aloe cooperi grows without a stem or with a short stem, usually single or occasionally sprouting and forming small groups. The 16 to 20 triangular, folded-keeled leaves with a V-shaped cross-section are arranged in two rows. Sometimes they are twisted in a spiral and form rosettes with age . The leaf blade is 60 to 80 inches long and 5 to 6 inches wide. The upper side of the leaf is green, indistinctly lined and occasionally covered with a few scattered spots near the base. There are numerous white spots on the underside near the base. The solid white teeth on the narrow, white, cartilaginous leaf margin are 1 to 2 millimeters long and 1 to 2 millimeters apart.

Inflorescences and flowers

The simple inflorescence reaches a length of 100 centimeters and more. The rather dense, broadly conical grapes are up to 20 centimeters long and 10 to 14 centimeters wide. They consist of about 40 flowers . The ovate long pointed bracts are 20 to 32 millimeters long. The salmon-pink, green-tipped flowers have 40 to 45 millimeter long peduncles . The flowers are 38 to 40 millimeters long and narrowed at their base. At the level of the ovary , they have a diameter of 12 millimeters. Near the mouth they are narrowed to about 9 millimeters. Their outer tepals are not fused together almost to the base. The stamens and the style stick out slightly from the flower.
