A tree about 60 ft. high; branchlets numerous, slender, longitudinally sulcate and dark purple when dry, glabrous. Leaves oblong-elliptic or elliptic, subacutely acuminate, broadly obtuse or slightly obtuse at the base, sometimes slightly oblique, 2 3/4–4 in. long, 1–1 3/4 in. broad, entire, thinly chartaceous, prominently reticulate on both surfaces, sometimes slightly shining above, glabrous above, minutely verruculose below; midrib prominent on both surfaces, nearly 1/2 lin. broad at the base; lateral nerves 7–8 on each side of the midrib, more prominent below than above, looped near the margin; veins rather close, distinct and somewhat prominent on both surfaces; petiole about 1/2 in. long, slightly puberulous or nearly glabrous; stipules caducous, lanceolate, about 1 3/4 lin. long, glabrescent. Receptacles axillary, solitary, pedunculate, subglobose, about 4 lin. in diam., light green and laxly reticulate when dry, smooth; peduncle 1 1/2–2 lin. long, minutely puberulous or nearly glabrous; basal bracts 3, broadly ovate, rounded at the apex, submembranous, convex below, glabrous except the minutely puberulous margin. Ostiole closed with transverse bracts; outer bracts horizontal, suborbicular, about 1 lin. broad, minutely puberulous, inner bracts gradually descending into the receptacle, a little more fleshy than the outer ones. Male flowers shortly pedicellate, with membranous perianth-segments and a solitary stamen. Female flowers sessile; perianth-segments membranous; style lateral, slender. Gall flowers pedicellate.
