Vegetative characteristics
Aloe wilsonii grows stem-forming, is simple or forms small groups. The usually short trunk is prostrate and occasionally reaches a length of up to 80 centimeters and is 6 centimeters thick. The approximately 24 lanceolate, narrowed leaves form a dense rosette . The deep green, yellowish, slightly shiny leaf blade is up to 25 centimeters long and 9 centimeters wide. There are sometimes a few concentrated white spots on the underside of the leaf. The piercing, reddish teeth on the light brown, horny leaf margin are about 3 to 4 millimeters long and 10 millimeters apart. The yellow leaf sap dries brownish.
Inflorescences and flowers
The inflorescence has about eight branches and reaches a length of 50 to 60 centimeters. The loose, cylindrical, pointed grapes are 15 to 18 centimeters long and 5 to 6 centimeters wide. The egg-shaped pointed bracts have a length of 5 millimeters and are 3 millimeters wide. The cloudy, scarlet, frosted flowers stand on 15 millimeter long flower stalks . They are 28 millimeters long and narrowed briefly at their base. At the level of the ovary , the flowers are 7 millimeters in diameter. In addition, they are very slightly narrowed and finally slightly expanded towards the mouth. Your outer tepals are not fused together over a length of 14 millimeters.
