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.
