description

Vegetative characteristics

Aloe madecassa grows easily and almost without a trunk. The approximately 20 lanceolate, pointed leaves form a dense rosette . The green, indistinctly lined leaf blade is about 25 centimeters long and 7 to 9 centimeters wide. The piercing, light pink teeth on the narrow, pink, cartilaginous leaf margin are 2 millimeters long and 5 to 8 millimeters apart. The leaf juice dries white.

Inflorescences and flowers

The inflorescence has six to ten branches and reaches a length of up to 100 centimeters and more. The loose, cylindrical, pointed grapes are up to about 20 centimeters long and 5 to 6 centimeters wide. The lanceolate, white bracts have a length of about 9 millimeters and are 3 millimeters wide. The slightly club-shaped, scarlet- red flowers stand on 14 millimeter long peduncles . The flowers are about 25 millimeters long and narrowed briefly at their base. At the level of the ovary they have a diameter of about 5 millimeters. Above it they are extended to the mouth. Your tepals are not fused together over a length of 12 millimeters. The stamens and the pen stand out 1 to 2 millimeters from the flower.
