A tree up to 50 ft. high, with a spreading habit; young branchlets leafy at the apex, very stout, villous. Leaves large, elongate-elliptic or narrowly oblong-elliptic, shortly and obtusely acuminate (acumen 1/3– 1/2 in. long), rounded and emarginate at the base, 9–12 in. long, 2 1/4–6 in. broad, entire, chartaceous or thinly coriaceous, glabrous, finely reticulate and dull above, pilose chiefly on the midrib and lateral nerves below; midrib flat or slightly impressed above, very prominent beneath, 2 lin. broad at the base, closely longitudinally ribbed when dry, gradually tapered to the apex; lateral nerves 12–14 on each side of the midrib, spreading at a wide angle from the midrib, slightly arcuate, looped near the margin, distinct on both surfaces, prominent below; tertiary nerves rather lax, zig-zag; venation rather close and conspicuous on both surfaces; petiole 1–3 in. long, compressed, about 2 1/2 lin. broad, villous with reflexed hairs when young, at length becoming merely puberulous; stipules caducous, those surrounding the terminal bud ovate, long and acutely acuminate, about 3/4 in. long, submembranous, hairy towards the base outside. Receptacles crowded towards the apex of the shoots, sessile, depressed-globose, 1/2– 3/4 in. in diam., finely long-pilose. Basal bracts large, enclosing the developing receptacles for some time, long-pilose outside. Ostiole small and pore-like; bracts all descending into the receptacle, glabrous. Male flowers shortly pedicellate. Stamen solitary. Female flowers sessile; style slender. Gall flowers pedicellate.
