description
Vegetative characteristics
Aloe fibrosa grows trunk-forming and branches out from the base. Upright trunks are up to 2 meters long and 3 centimeters in diameter. If they are supported by the surrounding vegetation they are longer, if they are prostrate they can reach a length of up to 2.5 meters. The trunks are covered with the remains of dead leaves. The lanceolate, pointed leaves are scattered along the stems. The bright green, sometimes reddish tinged leaf blade is 30 to 35 centimeters long and 3 to 6 centimeters wide. There are a few spots on young shoots. The firm, brown-pointed teeth on the leaf margin are 3 to 4 millimeters long and 15 to 17 millimeters apart. Fibers are present in the inner tissue, especially at the leaf base and the leaf sheaths .
Inflorescences and flowers
The inflorescence is simple or has one or two branches. It reaches a length of up to 100 centimeters. The dense, conical-cylindrical grapes are 10 to 20 centimeters long and 10 centimeters wide. The whitish, egg-shaped bracts have a length of 12 to 18 millimeters and are 7 millimeters wide. In the bud stage they are arranged in a brick shape. The orange-red flowers are yellowish at their mouth and are on 20 to 25 millimeter long peduncles . The flowers are 30 to 35 millimeters long and truncated at their base. At the level of the ovary , the flowers have a diameter of 8 to 9 millimeters. Above that, they are narrowed to 5 millimeters and finally expanded to 9 to 10 millimeters towards the mouth. Your outer tepals are not fused together over a length of about 10 to 11 millimeters. The stamens and the style stick out about 1 millimeter from the flower.
Systematics and distribution
Aloe fibrosa is common in Kenya and Tanzania on rocky slopes with dense shrubbery at altitudes of 1500 to 2000 meters.
