Branchlets longitudinally striate, lenticellate, otherwise glabrous. Leaves oblong or elliptic-oblong, acuminate, the acumen up to 7 lin. long, rounded at the base, 2–4 1/2 in. long, 3/4–1 3/4 in. broad, entire, rigidly coriaceous, dull and glabrous on both surfaces; midrib flat above, prominent below, about 1 lin. broad at the base, gradually tapered to the apex of the blade; lateral nerves about 6 on each side, arcuate, diverging from the midrib at an angle of 45°, looped some distance from the margin, prominent on both surfaces; veins distinct on both surfaces, rather close; petiole 1/2– 3/4 in. long, about 1 lin. thick, glabrous; stipules more or less deciduous, up to nearly 1/2 in. long and 2 lin. broad, glabrous. Receptacles sessile, in axillary pairs, obovoid-globose, about 5 1/2 lin. in diam., prominently warted, slightly puberulous. Basal bracts 2, suborbicular, membranous, glabrous. Ostiole inconspicuous, 2-lipped, with no bracts visible from the outside; bracts all pointing into the receptacle, oblong or oblong-lanceolate, glabrous. Male flowers shortly pedicellate; perianth-segments 3, unequal, linear or lanceolate, glabrous, about 3/4 lin. long. Stamen solitary; filament short; anther nearly 1/2 lin. long, obtuse. Female flowers with a short stout pedicel; perianth-segments 3, lanceolate, acute, 3/4 lin. long, membranous; achene obliquely obovoid, smooth; style inserted laterally, about one and a quarter times the length of the achene, with a unilateral stigma. Receptacular scales subulate-lanceolate, acute, 3/4–1 lin. long, membranous. Gall flowers with pedicels 3/4 lin. long, otherwise similar to the female.
