The 30 to 40 lanceolate, narrowed leaves form dense rosettes . The cloudy green leaf blade is 80 to 100 centimeters long and 15 to 20 centimeters wide. The slightly stabbing teeth on the leaf margin are 5 to 6 millimeters long and 15 to 20 millimeters apart. The leaf sap is deep purple when dry.
Inflorescences and flowers
The inflorescence consists of about twelve branches and reaches a length of about 90 centimeters. The lower branches are branched again. The rather dense, cylindrical, slightly pointed grapes are up to 15 centimeters long and 6 centimeters wide. The triangular bracts have a length of 8 millimeters and are 5 millimeters wide. The bright blood-red flowers stand on peduncles about 12 millimeters long . The flowers are about 28 millimeters long and truncated at their base. At the level of the ovary , the flowers are 6 to 7 millimeters in diameter. Above that they are narrowed and finally widened towards the mouth. Your outer tepals are not fused together over a length of 14 millimeters. The stamens and the style protrude up to 1 millimeter from the flower.
