Inflorescence about 1-3 cm long, much shorter than the leaves. Tepals small, (two decussate pairs) up to 1-1.5 mm long. Receptacle villous on the outer surface. Anthers about 1-1.5 mm long, each opening by a horseshoe-shaped slit, filaments short. Female flowers +/- operculate. Carpel characters not available.

At the tenth leaf stage: leaf blade obovate or narrowly obovate, apex apiculate, base cuneate, margin serrate, about 2-8 teeth on each side on the upper half of each leaf blade, upper surface hairy at least along the midrib. Petiole, stem and terminal bud clothed in pale golden hairs. Seed germination time 89 to 422 days.
