Vegetative characteristics

The yellowish-green to olive-green, strikingly lined-striped leaf blade is 25 to 30 centimeters long and 7 centimeters wide. The firm, pale yellow teeth on the leaf margin are 1 to 2 millimeters long and 3 to 5 millimeters apart.

Inflorescences and flowers

The inflorescence consists of two to four branches and reaches a length of about 80 centimeters. The rather dense, cylindrically pointed grapes are 25 centimeters long and 5 centimeters wide. The ovoid-pointed bracts are 4 to 7 millimeters long and 2 to 3 millimeters wide. The scarlet flowers stand on 14 millimeter long flower stalks . The flowers are 26 millimeters long and narrowed at their base. At the level of the ovary , the flowers are 4 to 5 millimeters in diameter. They are expanded beyond that. Your outer tepals are not fused together over a length of 9 millimeters. The stamens and the stylus barely protrude from the flower.
