The inflorescence has up to 15 branches and reaches a length of up to 140 centimeters. The branches are branched again. The rather dense, cylindrical-conical grapes are up to 35 centimeters long. The deltoid bracts have a length of 8 to 10 millimeters and are 3 to 6 millimeters wide. The red or yellow, hairy flowers are on 8 millimeter long peduncles and are 30 to 33 millimeters long. At the level of the ovary , the flowers have a diameter of 7 to 8 millimeters. Your outer tepals are not fused together over a length of 10 to 13 millimeters.
