On the underside of the leaf near the tip there are occasionally a few central spines. The leaf surface is rough. The brown or reddish brown teeth on the leaf margin are 2 to 3 millimeters long and 6 to 10 millimeters apart.

Inflorescences and flowers

The inflorescence is simple or consists of up to five branches. It reaches a length of 1 to 2 meters. The rather dense, cylindrical grapes are 35 to 40 centimeters long. The egg-shaped pointed bracts are 10 to 15 millimeters long and 6 millimeters wide. The red or yellow flowers are on 5 to 10 millimeter long peduncles . The flowers are about 30 millimeters long and rounded at their base. At the level of the ovary , the flowers have a diameter of 8 millimeters.
