Branchlets thick and stout, ribbed, about 1/2 in. thick just below the apex, pilose between the ribs. Leaves large, oblong-oblanceolate or somewhat pandurate, rounded or cordate at the base, shortly and obtusely acuminate, 6–20 in. long, 3 1/2–7 1/2 in. broad, entire, coriaceous, closely reticulate on both surfaces; midrib slightly grooved above when dry, very prominent below, nearly 1/4 in. broad at the base below; lateral nerves 8–10 on each side of the midrib, looped, distinct on both surfaces, very prominent below; tertiary nerves very lax and much branched below; petiole 1/2–2 1/2 in. long, stout, sharply and deeply ribbed, pubescent between the ribs; stipules not seen, soon caducous. Receptacles large, sessile in axillary pairs, subglobose, about 1 1/2–1 3/4 in. in diam., much wrinkled and tuberculate when dry, shortly pubescent. Basal bracts triangular-ovate, obtuse, about 3/4 in. long, chartaceous, adpressed-pubescent or subvillous outside, glabrous within.
