A tree up to about 80 ft. high; young branchlets short and twiggy, subterete, glabrous. Leaves small, obtriangular, mostly quite truncate, rarely slightly rounded, undulate or broadly emarginate at the apex, cuneate to an obtuse base, 1 1/2–3 in. long, 1 1/4–2 3/4 in. broad across the top, entire, chartaceous or rigidly subcoriaceous, glabrous and mostly somewhat dull on both surfaces; margins recurved; midrib prominent below, convex, abruptly two or three times divided about a third of its length from the apex, when thrice divided then the third division continuing the midrib towards the apex of the leaf but much fainter and usually again branched; lateral nerves 4–7 on each side, arising from the midrib at an angle of from 45°–65°, looped, the loops forming a wavy line parallel with and about 1 lin. from the margin; tertiary nerves and veins rather lax, distinct below; petiole 1/4– 3/4 in. long, 1/2– 3/4 lin. thick, glabrous; stipules caducous, small, lanceolate, acute, rusty-hirsute or tomentose on the outside. Receptacles in axillary pairs on the young annual shoots, pedunculate, globose, mammillate at the apex, 3–4 lin. in diam., smooth; peduncles 2 1/2–5 lin. long, glabrous or very minutely and sparingly puberulous; basal bracts connate into a saucer-shaped entire shortly ciliolate fleshy cup about 1/2 lin. high. Ostiole pore-like, gaping; bracts all descending into the receptacle, glabrous. Male flowers with a solitary stamen. Female flowers numerous, sessile; perianth cupular, 3-lobed, lobes triangular, acute, membranous, glabrous. Gall flowers pedicellate; pedicels red, glabrous; perianth as in the male, membranous.
