Tree, (8-) 12-24(-37) m, (15-)20-35 cm ø; bark smooth or finely cracked or hooped, sometimes patchy, whitish-greyish to greenish or greyish-brownish. Branchlets dark by resinous excretion. Leaves oblong to obovate, sometimes elliptic, apex generally rounded or obtusely apic-ulate, sometimes slightly retuse, rarely shortly bluntly acuminate, base cuneate, coriaceous, sometimes very stiffly so, shining above, rather dull beneath, the whole undersurface or at least the parts closer to the midrib set with fine epidermal tubercles, margin a little revolute, (6-)7-12(-16) by (3-)4-7(-9) cm, nerves numerous (20-25) straight subparallel pairs, generally slightly raised above only, rather obscure though visible beneath, reticulation, if any, remarkable above only; petiole 1.2-2 (very rarely-3) cm by 2(-3) mm. Cymes arranged in an umbel, its peduncle robust, 1-2(-3) cm by 2 mm, the (4-)5-6(-8) branches (3-)5-8 mm long and c. 1.5 mm ø, each branch bearing (1-)3-4(-5) distally crowded flowers; bract at base of umbel ovate-subulate, c. 2 mm, sub-persistent. Calyx broadly obconical, 3 mm, base rugulose, margin truncate or very shallowly (apiculately) lobed, the very edge almost pellucid and ciliolate (lens!). Petals broad-oblong, slightly keeled, (4-)5(-6) by 2(-2.5) mm, white or light brown, scented. Disk cup-shaped and shallowly lobed. Drupe ovoid, very apex rather abruptly attenuate, lower half glossy green, upper one dull grey, 3-3.5(-4) by 1.5-2.2 cm, the fibrous part of the endocarp 1 mm thick.
Primary forest, generally on hillside or high level alluvium, occasionally in swamp between hills, also in peat swamp forest, in coastal and high inland kerangas, on padang and on cliffs, generally in lowland up to 900 m, in the Cameron Highlands up to 1465 m, on Mt Murud in Sarawak at 1700 m, and on Mt Pagon Periok in Brunei at 1800 m; on Mt Kinabalu up to 1220 m, on sandy, maybe waterlogged soil (Agathis forest), sandy peat soil or sandy loam, rarely on sandstone.
