description

Vegetative characteristics

Aloe rigens usually grows without a stem, is solitary or forms small clumps. The approximately 24 ascending to almost upright, lanceolate narrowed, very stiff leaves form a dense rosette . The pale green leaf blade is 60 to 80 inches long, 12 to 15 inches wide and 1.5 to 2.5 inches thick. The pointed, deltoid teeth on the leaf margin are 4 to 6 millimeters long and 20 to 30 millimeters apart. The leaf juice dries yellow to orange in color.

Inflorescences and flowers

The inflorescence has three to four branches and reaches a length of 125 to 175 centimeters. The rather dense, cylindrically pointed grapes are 20 to 30 centimeters long and 6 centimeters wide. The ovoid-deltoid bracts have a length of up to 15 millimeters and are 6 millimeters wide. The pink- red to cloudy scarlet- red flowers are very short, downy-haired and are on 5 to 6 millimeter long peduncles . The flowers are 30 to 35 millimeters long and truncated at their base. At the level of the ovary , the flowers are 7 millimeters in diameter. Above this they are very slightly narrowed and finally widened towards the mouth. Your outer tepals are not fused together over a length of 10 to 12 millimeters. The stamens and the pen stand 2 to 4 millimeters out from the flower.
