A large tree; young leafy branchlets glabrous except the terminal buds, reddish-brown or purplish when dry. Leaves lanceolate or oblong-lanceolate, shortly and obtusely acuminate, rounded or obtuse at the base, 3–6 in. long, 1–2 1/4 in. broad, entire, thinly chartaceous, glabrous on both surfaces; midrib flat or slightly raised above, prominent below, about 1 lin. broad at the base, gradually tapered to the apex of the leaf-blade; lateral nerves 5–7 on each side of the midrib, the lowermost pair ascending at a sharp angle and reaching nearly to the middle of the blade, the others diverging at an angle of about 45°, slightly raised above, prominent below, rather slender, gradually fading away near the margin; tertiary nerves lax and very slender, distinct below; veins very delicate and indistinct; petiole 1–1 1/4 in. long, longitudinally sulcate, reddish-brown when dry, glabrous; stipules deciduous, those enclosing the terminal bud lanceolate, acutely acuminate, 1/2– 3/4 in. long, adpressed-pubescent, with glabrous margins. Receptacles borne in panicles mostly on the main-stem, pedunculate, subglobose, rounded or slightly stipitate at the base, about 1/2 in. in diam., glabrous; peduncle 3–4 lin. long, rather slender, finely puberulous. Basal bracts 3, small, broadly ovate, puberulous outside. Ostiole with numerous exserted glabrous bracts; innermost bracts very numerous, descending into the receptacle, linear, obtuse, 1 1/4 lin. long, glabrous. Male flowers sessile, with a membranous perianth enclosing the 2 subsessile anthers. Female flowers subsessile; style rather thick and short, with an oblong stigma.
