description
Vegetative characteristics
Aloe pruinosa grows easily and in a stem-forming manner. The prostrate trunks take root and reach a length of up to 50 centimeters. The 12 to 24 lanceolate, narrowed leaves form a dense rosette . The green leaf blade is up to 70 inches long and 8 to 10 inches wide. It is covered with numerous white spots that are scattered or arranged in transverse bands. The spots are more numerous on the underside of the leaf. The piercing, light pink-brown teeth on the leaf margin are up to 4 millimeters long and 15 to 20 millimeters apart. The leaf juice dries deep purple.
Inflorescences and flowers
The inflorescence has about eleven branches and reaches a length of up to 200 centimeters. The lower branches are branched again. The loose, cylindrical, pointed grapes are 10 to 30 centimeters long and 7 centimeters wide. The linearly lanceolate, pointed bracts have a length of 10 to about 20 millimeters. The cloudy dark brownish-red to pinkish-reddish white flowers are densely grayish powdery frosted and stand on 10 to 20 millimeter long flower stalks . They are 30 to 40 millimeters long and trimmed at their base. At the level of the ovary , the flowers have a diameter of 8 millimeters. Above this they are abruptly narrowed to 5 millimeters and finally widened again to 8 millimeters at the mouth. Your outer tepals are not fused together over a length of 7 millimeters.
