Leaves ovate-oblong to lanceolate, (20-)25-45 by 7-15 cm, usually emarginate, sometimes rounded at the base, acute to ± acuminate at the top, tip obtuse, glabrous, coriaceous, distinctly and ± prominently reticulate beneath; nerves 15-25 pairs; petiole 5-10(-15) mm, 2-5 mm Ø, glabrous. Inflorescence ramiflorous, 45-90 cm, always branched up to the third order, without distinct peduncle, pendulous, woody, with spreading axes; main axis terete; primary axes many, not always paired; racemules up to 30 cm. Bracts of axes triangular, c. 1 mm, caducous. Bracts of the flowers subulate, c. 1 mm, persistent. Pedicels 1-3 mm, c. ½ mm Ø. Receptacle ± flat, 1-1½ mm wide, puberulous, not densely papillose inside. Sepals deltoid, c. 1 mm, inside with a longitudinal densely puberulous crest. Stamens 4; filaments 1½-3 mm, glabrous, at the very base puberulous; connective c. ½ mm, more or less conduplicated; anthers ± linear, ½ by 0.1-0.2 mm, ± introrse. Ovary pyramidal, 4-celled, 1-2 mm, puberulous, more or less episeptally impressed; style (l-)1½-2½(-3) mm, c. ¼ mm Ø, puberulous; stigma truncate, hardly wider than the style.
