description
Vegetative characteristics
Aloe classenii grows without a trunk or trunk-forming, sprouts from the base and forms dense groups. The trunks are up to 50 centimeters long. The approximately 24 lanceolate leaves form dense rosettes . The dark olive-green, reddish expectant on exposed parts leaf blade is 35 to 50 centimeters long and 7 to 8 centimeters wide. There is a terminal mandrel at the tip of the blade . On the underside of the leaf there are occasionally a few bright, elongated spots near the base. The leaf surface is smooth. The piercing, light brown teeth on the leaf margin are 5 millimeters long and 10 to 15 millimeters apart. The leaf sap is dry yellow.
Inflorescences and flowers
The inflorescence consists of about ten branches and reaches a length of about 60 centimeters. The lower branches are also branched. The loose, cylindrical, pointed grapes are about 7 inches long and 4 inches wide. The ovoid-pointed bracts are 3 millimeters long. The dark wine-red, powdery, frosted flowers stand on 8 to 10 millimeter long flower stalks . The flowers are 20 to 25 millimeters long and rounded at their base. At the level of the ovary , the flowers are 7 millimeters in diameter. They are not narrowed beyond that. Your outer tepals are not fused together over a length of 10 millimeters. The stamens and the pen stand out 3 to 4 millimeters from the flower.
Systematics, distribution and endangerment
Aloe classenii is widespread in Kenya in humus pockets on gneiss deposits at an altitude of around 600 meters.
