description
Vegetative characteristics
Aloe thompsoniae grows without a trunk or with a very short trunk, sprouts and branches from the base and forms dense groups. The 12 to 18 lanceolate, narrowed leaves are arranged in multiple rows in rosettes on the shoots. The green, indistinctly lined leaf blade is 15 to 20 centimeters long and about 1.5 centimeters wide. On it there are a few scattered white elongated spots near the base. They are more numerous and rounded on the upper side of the leaf. The firm, white teeth on the leaf margin are about 1 millimeter long and 1 to 2 millimeters apart.
Inflorescences and flowers
The simple inflorescence reaches a length of up to 20 centimeters. The dense, pyramidal-headed grapes are 3 to 4 inches long and 4 to 5 inches wide. The egg-shaped pointed bracts have a length of about 10 millimeters and are 5 to 6 millimeters wide. The coral-red flowers are on 15 to 20 millimeter long peduncles . They are 25 to 28 millimeters long and briefly narrowed at their base. Above the ovary , the flowers are not narrowed. Your outer tepals are not fused together. The stamens and the stylus do not protrude from the flower.
Systematics and distribution
Aloe thompsoniae is common in the South African province of Limpopo on rocky cliffs at altitudes of 1600 to 2100 meters.
