A tree up to 30 ft. high (Chipp); stems twiggy (Vogel); branchlets smooth, covered with glabrous straw-coloured bark. Leaves oblong or oblong-elliptic, shortly and obtusely or caudately long-acuminate, when long-acuminate then the acumen somewhat oblique (in the dried leaves), rounded or very slightly cuneate at the base, 2 1/2–6 in. long, 1–2 1/4 in. broad, thinly chartaceous or almost membranous, glabrous on both surfaces, mostly much darker coloured above, very finely reticulate below; midrib slightly impressed above, prominent but rather slender below, scarcely 3/4 lin. broad at the base, gradually tapered to and almost fading away at the apex; lateral nerves 7–10 on each side, spreading from the midrib at an angle of about 65° or almost at right angles, slender, looped, the loops forming a rather deeply crenate line about 1 lin. from the margin; veins very slender and rather close, not visible above, distinct (but only very slightly raised) below; petiole 3/4–1 3/4 in. long, glabrous, about 3/4 lin. thick; stipules very caducous, present only at the apex of the newly opened shoots, linear-lanceolate, very acutely acuminate, about 1/2 in. long, glabrous. Receptacles in axillary pairs, or perhaps sometimes also fasciculate on the older branches, pedunculate, subglobose when ripe, stipitate at the base when young, at length rounded, 1/2 in. or slightly more in diam., very finely rusty-puberulous when young, at length glabrous. Basal bracts soon falling off, connate at the base into a persistent circular plate closely applied to the receptacle. Ostiole small and 2-lipped; bracts all descending into the receptacle, subacute, glabrous. Male flowers shortly pedicellate; perianth-segments lanceolate, membranous, glabrous. Stamen solitary. Female flowers subsessile. Gall flowers shortly pedicellate, numerous.
