description
Vegetative characteristics
Aloe thorncroftii grows stemless or occasionally short stem-forming and is simple. The approximately 25 to 30 lanceolate leaves form a rosette . The cloudy gray-green, indistinctly lined leaf blade is reddish green towards the tip and is up to 40 centimeters long and 10 to 14 centimeters wide. The leaf surface is rough. The stinging, reddish-brown teeth on the leaf margin are 3 to 4 millimeters long and 8 to 12 millimeters apart.
Inflorescences and flowers
The simple, rarely branched inflorescence reaches a length of up to 100 centimeters. The loose, cylindrical, pointed grapes are 40 to 50 centimeters long. The lanceolate-egg-shaped, thick and fleshy bracts have a length of 20 millimeters and are 15 millimeters wide. In the bud stage, they are densely arranged in a brick shape. The cloudy pink to scarlet, light bluish gray frosted flowers are on 20 millimeter long peduncles . They are up to 55 millimeters long and narrowed briefly at their base. Above the ovary , the flowers are slightly expanded and finally narrowed slightly towards the mouth. Your outer tepals are not fused together over a length of 20 millimeters. The stamens and the stylus barely protrude from the flower.
Systematics and distribution
Aloe thorncroftii is common in the South African province of Mpumalanga between rocks on mountain slopes at altitudes of 1400 to 1500 meters.
