description
Vegetative characteristics
Aloe bussei grows without a trunk, sprouts and forms dense groups. The approximately 20 ovate-lanceolate leaves are pointed and form rosettes . Their shiny green, mostly coppery-red tinged leaf blades are 20 to 30 centimeters long and 5 to 6 centimeters wide. Occasionally there are a few whitish spots on the underside of the leaf. On the narrow, white, cartilaginous leaf margin sit white or light yellowish teeth that are inclined towards the leaf tip and are 2 to 3 millimeters long. The peripheral teeth are 7 to 15 millimeters apart.
Inflorescences and flowers
The inflorescence is simple or usually consists of one to four branches and reaches a length of 40 to 60 centimeters (rarely up to 75 centimeters). The more or less dense, conical-cylindrical grapes are 15 to 25 centimeters long. The ovoid-pointed bracts are 4 to 6 millimeters long and 3 millimeters wide. The coral-red flowers are yellowish at their mouth and stand on 8 to 10 millimeter long peduncles . The flowers are 28 to 35 millimeters long and narrowed at their base. At the level of the ovary , they have a diameter of 6 millimeters. They are slightly narrowed above this, then widened to 8 millimeters and narrowed again at the mouth. Your outer tepals are not fused together over a length of 12 to 15 millimeters. The stamens and the style stick out slightly from the flower.
Systematics, distribution and endangerment
Aloe bussei is common in Tanzania on rock deposits and cliffs at altitudes of 580 to 1500 meters.
The first description by Alwin Berger was published in 1908. A synonym is Aloe morogoroensis Christian (1940).
Aloe Bussei is in the endangered Red List species the IUCN as " Vulnerable (VU) ", d. H. classified endangered.
