Emergent tree up to 51 m tall and 109 cm dbh. Stipules absent. Leaves
alternate, simple, penni-veined. Flowers ca. 10 mm in diameter,
white-yellow-pinkish coloured, placed in panicles. Fruits ca. 15 mm long,
reddish, winged nut (wings formed by enlarged sepals).
In undisturbed dry or swampy forests, sometimes in peat swamp forest, rarely
on limestone. Growing up to 1000 m altitude, but usually below 500 m. In
secondary forests usually present as a pre-disturbance remnant.
The timber is regarded of superior quality, but a great objection against
its use is that it retains its renghas-poison for a long time. The fruits are
used to make dart poison.
