description
Vegetative characteristics
Aloe swynnertonii grows without a stem or with a very short stem, is simple or forms small groups of three to four rosettes . The approximately 20 lanceolate, narrowed leaves form dense rosettes . The leaf blade is up to 75 inches long and 8 to 10 inches wide. Your top four inches will soon dry up. On the dark green upper side of the leaves there are elongated to confluent, H-shaped spots that form irregular transverse bands. The underside is lighter green, lined and usually not spotted. The reddish brown, stinging teeth on the leaf margin are 4 millimeters long and 10 to 25 millimeters apart. The leaf sap is dry yellow.
Inflorescences and flowers
The inflorescence consists of eight to twelve branches and reaches a length of 150 to 175 centimeters. The lower branches are occasionally branched again. The dense, heady, ebony grapes are 6 to 8 inches long and 7 to 8 inches wide. The deltoid bracts have a length of 8 millimeters and are 3 millimeters wide. The flesh-pink to cloudy coral-red, slightly frosted flowers are on 25 to 30 millimeter long peduncles . The flowers are 30 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 suddenly narrowed to 5 millimeters, then expanded again and finally narrowed towards the mouth. Your outer tepals are not fused together over a length of 9 millimeters. The stamens and the style protrude up to 1 millimeter from the flower.
Systematics and distribution
Aloe swynnertonii is widespread in the border area between Zimbabwe and Mozambique in the mountainous grasslands at altitudes of 800 to 1800 meters.
