The ten to 18 leaves are scattered along the trunk. The greyish green, not spotted leaf blade is 30 to 50 centimeters long and 2 to 4 centimeters wide. The leaf surface is smooth. The white, reddish-tipped teeth on the leaf margin are up to 1 millimeter long and 3 to 5 millimeters apart. They can also be absent. The leaf juice dries yellow.

The loose, cylindrical grapes are 15 to 30 centimeters long and consist of single-sided flowers. The white, ovate-pointed bracts are 4 to 5 millimeters long and 2.5 millimeters wide. The bright scarlet flowers turn pale to almost white at the mouth. They stand on 6 to 7 millimeter long flower stalks .
