The plant is glabrous or sparsely hairy with short, simple, snug, up to 0.5 mm long trichomes. The leaf blades are ovate to ovate - lanceolate or broadly lanceolate. They are 2.5 to 10 ( rarely to 13) cm long and 1-6 (rarely to 7) inches wide. They are glabrous or sparsely hairy with short, striegel hairy trichomes. The leaf margin is entire or coarsely toothed with few teeth, the base is truncated or rounded, forward the leaf blade is sharp. Petioles have about one to two fifths of the length of the leaf blade.
The flowers appear singly in the axils of the leaves. The flower stem measures 5 to 20 millimeters. In its heyday, the cup is 7 to 12 (rarely 5-15 ) mm long and sparsely occupied with striegel haired, short, adjacent trichomes. The sepals are 3-6 mm long.
