A tree 30–50 ft. high; young branchlets leafy towards the apex, strigose-hirsute. Leaves obovate or obovate-elliptic, shortly and subacutely acuminate, rounded or slightly cordate at the base, 4–8 in. long, 1 3/4–5 in. broad, rather coarsely undulate-dentate, thinly chartaceous or almost membranous, glabrous above except for a few hairs sometimes on the midrib, long-pilose with rust-coloured hairs chiefly on the midrib and lateral nerves beneath; midrib slightly raised above, prominent below, scarcely 3/4 lin. broad at the base; lateral nerves 6–7 on each side of the midrib, the basal pair opposite, the others subopposite to alternate, diverging from the midrib at an angle of 45°, slightly arcuate, looped close to the margin, distinct above, prominent below; tertiary nerves subparallel, 2–3 lin. apart, linking the lateral nerves at right angles, prominent below; veins rather close but rather indistinct below; petiole 3/4–2 3/4 in. long, at first pubescent, at length glabrous or nearly so; stipules subpersistent, lanceolate or ovate-lanceolate, acutely acuminate, about 1/2 in. long, submembranous, glabrous. Receptacles paniculate, mostly at the base of the trunk (Vogel); panicles long and slender, leafless, up to 2 ft. long; lateral branches up to 2 1/2 in. long, glabrous or slightly pubescent. Receptacles somewhat obovoid, a little more than 1/2 in. in diam., setose-pilose with yellowish hairs. Basal bracts 2, slightly connate at the base, ovate, about 1 3/4 lin. long and broad, pilose. Ostiole prominent; bracts spreading horizontally across the ostiole, rounded, membranous, glabrous, the innermost ones descending into the receptacle, linear. Male flowers sessile, near the ostiole; perianth-segments unequal, membranous, enclosing the pair of stamens like a cloak. Female flowers subsessile with long slender styles. Gall flowers pedicellate.
