The obscure, slightly downy-haired leaves are 3 to 7 inches long, 1.3 to 3 inches wide and 0.1 to 0.15 inches thick. They are pointed towards the tip. The base is wedge-shaped. The top of the leaf is glossy. There are clear brownish, tannic longitudinal stripes on the leaves. The edge of the leaf is covered with conical eyelashes up to 0.3 millimeters long and some additional hairs that are 0.1 to 0.5 millimeters long.
