description
Vegetative characteristics
Aloe wollastonii grows without a trunk and usually grows easily. The 12 to 15 lanceolate, narrowed leaves form a dense rosette . The cloudy green leaf blade is 40 to 50 inches long and 8 to 10 inches wide. There are numerous elongated whitish spots on it, which are arranged in irregular transverse bands. The leaf surface is smooth. The stinging, red-brown teeth on the leaf margin are 4 to 6 millimeters long and 10 to 20 millimeters apart.
Inflorescences and flowers
The inflorescence has four to six branches and reaches a length of up to 125 centimeters. The lower branches are occasionally branched again. The loose, cylindrical-conical grapes are 10 to 30 centimeters long and 80 centimeters wide. The linear-lanceolate bracts have a length of 10 to 20 millimeters and are 4 millimeters wide. The rose-reddish to orange-red, rarely yellow flowers are on 15 to 20 millimeter long peduncles . They are 30 to 35 millimeters long and trimmed at their base. At the level of the ovary , the flowers have a diameter of 8 to 10 millimeters. Above this they are suddenly narrowed to about 6 millimeters and finally widened towards the mouth. Your outer tepals are not fused together over a length of about 10 to 12 millimeters. The stamens and the stylus barely protrude from the flower.
Systematics and distribution
Aloe wollastonii is found in Kenya , Tanzania , Uganda and Zaire often on moist grasslands and open woodlands at altitudes of 1100 to 2285 meters.
