Vegetative characteristics
Aloe tugenensis grows in a stem-forming manner and branches out from or near the base. The upright to ascending trunk is up to 70 centimeters long. Over time it becomes prostrate and is up to 120 centimeters long and 3 centimeters thick. It is covered with perennial dead leaves. The 12 to 20 lanceolate, narrowed leaves form a rosette . The cloudy green, brownish red tinged leaf blade is up to 61 centimeters long and 12 centimeters wide. There are several scattered whitish spots on young shoots. The leaf surface is slightly rough. The firm, hooked, brown-tipped teeth on the leaf margin are up to 5 millimeters long and 6 to 15 millimeters apart. The yellow leaf sap dries brownish yellow.
Inflorescences and flowers
The inflorescence has up to twelve branches and reaches a length of 95 to 130 centimeters. The lower branches are occasionally branched again. The rather dense, cylindrical grapes are 10 to 24 centimeters long. The linear bracts have a length of 11 millimeters and are 4 millimeters wide. They are arranged in the shape of a brick in the bud stage. The light pink, whitish-edged flowers are on 7 to 9 millimeter long peduncles . They are 22 millimeters long and narrowed briefly at their base. At the level of the ovary , the flowers have a diameter of 5 millimeters. Above this they are narrowed to 4.5 millimeters and finally widened to 7 millimeters towards the mouth. Your outer tepals are not fused together over a length of 14 to 15 millimeters. The stamens and the pen stand out 4 to 6 millimeters from the flower.
