Information

A large tree with smooth light brown bark; branchlets very stout, minutely puberulous. Leaves broadly elliptic or slightly pandurate, rather deeply cordate at the base, rounded at the apex, 5 1/2–10 in. long, 3 1/2–8 in. broad, entire, rigidly chartaceous, glabrous above, very minutely puberulous below, 5–9-nerved at the base, remaining lateral nerves 8–9 on each side, bifurcate some distance from the margin, looped, diverging from the midrib at an angle of about 75°, flat but distinct above, prominent below; tertiary nerves parallel, fairly close, spreading from the lateral nerves at right angles, rather slender; veins very fine and close, visible only on the lower surface; midrib flat above, very prominent below, about 2 lin. broad at the base, gradually narrowed to and bifurcate near the apex of the leaf; petiole 3–5 in. long, 1 1/2–3 lin. thick, shortly and softly pubescent; stipules deciduous, coriaceous, triangular, 4 lin. long, about 3 lin. broad, softly tomentose outside. Receptacles axillary, 2–3 together, pedunculate, subglobose, about 5 lin. in diam., densely pilose or glabrous and then often warted; peduncle 1/2– 3/4 in. long, densely pubescent; basal bracts 2, connate at the base, ovate, about 1 1/4 lin. long, membranous towards the margin, puberulous. Ostiolar bracts all descending, linear, obtuse, 1 1/4–1 3/4 lin. long, 1/3 lin. broad, membranous, glabrous. Male flowers few, near the ostiole, with a very short thick stalk; perianth membranous, enclosing the solitary sessile stamen. Gall flowers numerous, pedicellate. Female flowers shortly stalked; perianth-segments ovate-lanceolate, subacute, 1/2 lin. long, membranous, glabrous; ovary obovoid, 3/4 lin. long, glabrous; style lateral, inserted between the middle and the top of the ovary; stigma rather thick, oblong.
