Branches terete, covered with a grey glabrous bark; young branchlets rather slender, glabrous. Leaves oblong, subacutely caudate-acuminate (acumen in the mature leaves about 1/2 in. long), rounded at the base, 4–5 in. long, 1 1/3–1 3/4 in. broad, entire, thinly chartaceous, closely punctate and glabrous above, minutely puberulous on the midrib and lateral nerves below especially when quite young, dull on both surfaces, finely reticulate below, 3-nerved at the base, remaining lateral nerves about 7 on each side, slender, diverging from the midrib almost at right angles, looped, the loops forming a coarse crenate line about 1 1/4 lin. from the margin, distinct on both surfaces, prominent below; tertiary nerves very lax, fairly distinct below; veins forming a close network but scarcely prominent below; petiole 3/4–2 in. long, slender, scarcely 3/4 lin. thick, minutely puberulous when young, soon becoming glabrous, black when dry; stipules caducous, present only at the tips of the shoots, linear-lanceolate, very acute, 3/4–1 1/4 in. long, submembranous, with wavy thinner margins. Receptacles axillary or arising from the axils of fallen leaves, ellipsoid-globose, 3/4–1 in. long, puberulous or nearly glabrous; peduncle about 1/2– 3/4 in. long. Basal bracts reduced to a very small ring. Ostiole small, scarcely prominent, with linear descending bracteoles only. Male flowers with 1 stamen. Anther thick, obtuse. Female flowers few.
