Aloe sheilae grows without a stem or sometimes with a short stem, is single or occasionally forms two to three basal offshoots. The deltoid, pointed leaves form a loose rosette . The green leaf blade is up to 55 inches long and 6.5 inches wide. There are often a few light green rounded spots on it. The leaf surface is rough, the cartilaginous leaf margin narrow and white. Marginal teeth are absent or they are white, pointed brown, up to 1.5 millimeters long and 30 to 80 millimeters apart.
Inflorescences and flowers
The inflorescence has two to four (rarely up to seven) branches and reaches a length of 50 to 70 centimeters. The rather dense grapes are almost head-shaped or conical. The ovoid-deltoid bracts are 5 to 7 millimeters long and 3 to 4 millimeters wide. The coral-red, yellowish flowers are on 15 to 18 millimeter long peduncles . They are 30 to 35 millimeters long and narrowed at the base. At the level of the ovary , the flowers have a diameter of 5 millimeters. Above this they are slightly narrowed and finally widened towards the mouth. Your outer tepals are not fused together over a length of 20 millimeters. The stamens and the style protrude 5 to 7 mm from the flower.
