The cloudy green, indistinctly striped leaf blade is up to 50 centimeters long and 10 to 12 centimeters wide. As a rule, there are scattered white spots on it. The stinging, red-brown teeth on the leaf margin are 4 to 5 millimeters and 10 to 20 millimeters apart.
Inflorescences and flowers
The inflorescence consists of three to ten branches and reaches a length of 1 to 2 meters. The dense, heady grapes are 5 to 6 inches long and 8 to 10 inches wide. The deltoid, pointed bracts have a length of 10 to 12 millimeters and are 3 millimeters wide. The scarlet, orange or pink flowers are on 30 millimeter long peduncles . The flowers are 35 to 40 millimeters long and truncated at their base. At the level of the ovary , the flowers have a diameter of 10 millimeters. Above this they are suddenly narrowed to 5 to 6 millimeters and finally widened to the mouth. Your outer tepals are not fused together over a length of 12 to 13 millimeters. The stamens and the stylus barely protrude from the flower.
