The gray-green, bluish tinged leaf blade is 45 to 60 centimeters long and 6 to 7 centimeters wide. As a rule, there are a few scattered whitish spots on it near the base. The leaf surface is smooth. The piercing, reddish-brown teeth on the leaf edge are 4 millimeters long and 10 to 12 millimeters apart. The leaf juice dries up a little purple.
Inflorescences and flowers
The inflorescence has up to ten branches and reaches a length of up to 100 centimeters. The rather dense, cylindrically pointed grapes are 10 to 20 centimeters long and 7 centimeters wide. The ovoid-pointed bracts are 4 to 7 millimeters long and 2 to 3 millimeters wide. The scarlet flowers turn orange at the mouth and stand on 12 to 15 millimeter long peduncles . They are 25 to 30 millimeters long and briefly narrowed at the base. At the level of the ovary , the flowers are 7 millimeters in diameter. They are then narrowed towards the mouth. Your outer tepals are not fused together over a length of 12 millimeters. The stamens and the pen stand out 2 to 5 millimeters from the flower.
