Leaves: Leaves simple. Alternate. Blades elliptic, elliptic–ovate, or ovate, 7–15 cm long, 3–5.5 cm wide. Apex long-acuminate or acute. Base cuneate to rounded. Upper surfaces sparsely silky pubescent, the hairs somewhat spreading or appressed, 0.2–0.4 mm long; lower surfaces moderately silky pubescent, the hairs appressed or somewhat spreading, 0.3–0.6 mm long, their tips primarily directed toward apex and margins, grayish to greenish on lower surface, thin, with disciform cystoliths. Margins coarsely dentate above the middle or entire. Palmately 3-veined from base. Petioles 0.8–3 cm long, pubescent with appressed and spreading hairs. Stipules small, intrapetiolar.

Flowers: Flowers in axillary clusters, staminate flowers on pedicels 0–1 mm long; pistillate flowers sessile. Flowers unisexual (and the plants dioecious), actinomorphic.
