Tree up to 40 m. Twigs glabrous. Leaves elliptic to ovate-oblong, (5-)8-25 by (3-)4-14 cm, usually emarginate sometimes rounded or acute at the base, acute, sometimes acuminate at the top, tip mostly obtuse, glabrous, coriaceous, distinctly and slightly prominently reticulate beneath; nerves 6—12(-15) pairs; petiole 2-10(-15) mm, 1-4 mm Ø, glabrous. Inflorescence terminal, at the end of main or side twigs, 10-25(-35) cm, branched up to the first, second or third order, whether or not peduncled, erect, with flaccid to stiff and sublignose axes; main axis more or less flattened; primary axes 5-25, paired or irregular, sometimes in whorls of 4; racemules up to 15 cm. Bracts of axes triangular, 2-10 mm, sometimes present as small or reduced leaves, persistent or caducous. Bracts of flowers narrowly triangular, ½-l½ mm, persistent. Pedicels 1½-2 mm, c. ½ mm Ø. Receptacle ½-1¼ mm high, l½-2½ mm wide, densely whitish papillose inside. Sepals 5, triangular, l-l¼(-l½) mm, inside mostly with a longitudinal densely puberulous crest. Stamens 5; filaments 1-2½ mm, glabrous; connective c. ¼ mm, slightly conduplicated; anthers linear or semiorbicular, c. ¼(-½) by 0.1-0.2 mm, ± latrorse. Ovary subglobose, 3-celled, 1-1½ mm, whitish papillose and/or puberulous; style (l-)1½-2½ mm, 0.2-0.4 mm Ø, more or less shortly puberulous to papillose; stigma punctate to slightly capitate. Ovules inserted on the somewhat conically elevated edges between the bases of the septs. Capsule (sub)globose, more or less episeptally impressed, c. 2 mm; valves 3. Seeds c. ¾ by c. ¼ mm, apical and basal part of wing from ½ to 1 times as long as the seed proper.
Primary and secondary forests, on ridges, slopes, and along riverbanks, usually at low altitude, but also in the hills to 1200 m, once even found at 1800 m (Central Celebes, Malili area: B. Takale Kadju).
