description
Vegetative characteristics
Aloe comosa grows individually and in a stem-forming manner. The trunks are up to 2 meters long and covered with the perennial remains of dead leaves. The lanceolate, sword-shaped leaves form dense rosettes . The leaf blade is up to 65 inches long and 12 inches wide. Their glauken to slightly brownish pinkish upper side is indistinctly lined. The underside is bluish green. The brownish-red teeth on the pinkish-red leaf margin are 1 to 2 millimeters long and 5 to 10 millimeters apart.
Inflorescences and flowers
The mostly simple inflorescence reaches a length of up to 2 meters. Occasionally a branch is formed. The dense, narrow cylindrical grapes are 100 centimeters long and 8 centimeters wide. The lanceolate bracts taper to a point and are 40 millimeters long. In the bud stage, they are arranged in a brick shape and tufted at the tip of the inflorescence. The usually pink-cream to pinkish-ivory-colored, occasionally deep pink and frosted flowers stand on approximately 20 millimeters long, almost upright pedicels and are bulbous. The flowers are up to 40 millimeters long and very short at their base. Above the ovary , they are expanded to a diameter of 12 millimeters in the middle and then narrowed towards the mouth. Your outer tepals are not fused together for about 20 millimeters of their length. The stamens and the pen stand out 10 to 12 millimeters from the flower.
