Flowers and fruits as a shrub about 2-3 m tall.
Leaf blades about 10-13 x 8-9 cm, petioles about 4.5-6 cm long, margins with about 30-40 coarse teeth on each side. Underside of the leaf blade almost pure white in colour from the dense covering of felty hairs between the reticulate veins. Upper surface of the leaf blade scabrous. Stipules linear, caducous, about 4-8 mm long, two-awned at the apex. Petiole grooved on the upper surface. Twig bark strong and fibrous when stripped. Twigs clothed in white hairs. Reticulate veins run +/- at right angles to the midrib.
Fruits very small, in clusters on the twigs back from the leaves. Nuts about 0.5-0.7 mm long, resemble small seeds.
Cotyledons +/- orbicular, small, about 1-1.5 mm diam. First pair of leaves opposite and both the upper and lower surfaces of the leaf blade hairy. At the tenth leaf stage: leaves cordate or orbicular, apex acuminate, base rounded, margin dentate, underside white from matted hairs between the reticulate veins, upper surface somewhat scabrous. Stipules two-awned at the apex, about 4-5 mm long. Seed germination time 9 to 377 days.
