It is a large tree, 50 m in height and 182 cm in diameter. The crown is flat, irregular and open. The leaves are simple, alternate, ovate, acuminate at the apex, rounded at the base and smooth. The secondary nerves are pairs of six, prominent and further apart. The blade (leaf) is 10-14.5 cm long. The inflorescence is paniculate, 22 cm long if terminal, 14 cm long if axillary, singly or doubly branched; the branchlet is 4 cm long. The flowers are 7 mm long and 4 mm wide, ovoid, lanceolate; the sepals are ovate, obtuse, the outer three somewhat larger; the petals are broadly oblong, elliptic, acute; the stamens are 15, subequal; the anther cells are linear and as long as the stout appendages; the style is columnar, about thrice the length of the ovary. The fruit (nut) is enclosed by two long wings (up to 13 cm), one medium-sized wing (8 cm) and two small wings (about 4 cm). A healthy mature seed is elongated, 3-4 cm long. The wings at the base are contorted (“contorta”) around the nut.
