A robust umbrella-shaped tree; branchlets stout, glabrous except when very young. Leaves obovate or obovate-elliptic, rounded at the apex, more or less cuneate at the base, 3–10 in. long, 2–5 1/2 in. broad, rigidly and rather thinly coriaceous, margins often undulate, slightly rough on the upper surface, floccose-pubescent below; lateral nerves 13–19 on each side, in the older leaves diverging almost at right angles from the midrib, indistinctly looped almost at the margin, usually undivided, raised on the lower surface; tertiary nerves indistinct, more or less parallel; petiole very stout, up to 3 lin. in diam. and 3/4 in. long, shortly pubescent or glabrous. Male flower-heads borne on the previous year's growth, in fascicles: peduncles glabrescent, 1/4–2 in. long. Bracts of the involucre 5–6, broadly elliptic, 3–4 lin. long, 1 1/2–2 lin. broad, membranous, glabrous, margin slightly undulate. Calyx membranous, irregularly lobed; lobes filiform, glabrous. Filaments short, glabrous. Rudimentary ovary obconic, truncate, pilose towards the top. Female flowers: Peduncle about 3 lin. long, sparingly pubescent. Bracts of the involucre as in the male. Calyx cupular, very small, and shortly lobed, coriaceous, glabrous. Ovary 4-celled, ovoid, 2 1/2 lin. in diam., whitish-tomentose, almost hidden by the reflexed spreading styles; styles 4, reflexed, fan-shaped, lobed to the middle, 2 1/2 lin. long, 3 lin. broad, lobes numerous, linear, subterete. Fruit subglobose, 3–4-celled, about 1 in. in diam., glabrous when mature; exocarp 1/2 lin. thick, crustaceous. Pyrenes deeply grooved on the back.
