Characteristics

Tree up to 40 m, 60 cm Ø. Twigs glabrous. Leaves elliptic-oblong to ovate-oblong, (5-) 10-25 (-35) by 5-12(-15)cm, rounded or emarginate at the base, acute, sometimes acuminate at the top, tip usually obtuse, sometimes acute, glabrous, coriaceous, distinctly and slightly prominently reticulate beneath; nerves (8—)10—15(—18) pairs; petiole (2-)5-10 mm, 2-5 mm Ø, glabrous. Inflorescence axillary, one or a few together below the leaves on older nodes, 15-50 cm, only with primary side axes, very rarely with a few secondary side axes near the base, without distinct peduncle, sublignose, often ferrugineously pubescent, with pendulous axes; main axis terete or somewhat flattened, finely ribbed; primary axes 8—12(—15), not always paired, finely ribbed; racemules up to 50 cm. Bracts of axes triangular, c. 1 mm, mostly caducous. Bracts of flowers subulate, c. 1 mm, persistent. Pedicels ½-1(-½)mm, c. ½ mm Ø. Receptacle c. 1 mm high, 2-3 mm wide, densely whitish papillose inside. Sepals triangular, 1½-2 mm. Stamens 5; filaments 3-4mm, glabrous; connective ¼-½ mm, slightly conduplicated; anthers linear, ¼-½ by c. 0.1 mm, ± latrorse. Ovary (sub)globose to pyramidal, 3-celled, c. 1 mm, more or less fine whitish papillose whether or not with longer hairs in between; style (1½-)3-4(-5) mm, c. ¼ mm Ø, sparsely puberulous; stigma slightly capitate. Ovules inserted on the somewhat conically elevated edges between the bases of the septa. Capsule (sub)globose, c. 2 mm; valves 3. Seeds 0.3-0.4 by c. 0.2 mm, apical and basal part of wing about 1½ times as long as the seed proper.
