glabrescent, leaf-scars large, terminal bud slender, 3-5 cm by 7-9 mm, densely ferrugineously woolly
pubescent; pith thick, with many small vascular strands, appressed to the thin wood-cylinder.
Stipules none. Leaves often nearly in whorls of four, (3-)4-6-jugate. Leaflets nearly sessile,
lanceolate to oblong, 5-28(-33) by (2-)3-10(-12) cm, subcoriaceous, subglabrous above, densely
minutely tomentose to sparsely stellately pubescent or nearly glabrous
beneath; base rounded to subcordate; margin minutely serrulate (to subentire); apex rather
abruptly, shortly acute-acuminate; nerves 20-25 pairs (angle variable), tortuous, more or less
distinctly arching towards the margin, prominent beneath; reticulations very dense, waffle-like
beneath. Inflorescences (female unknown) axillary, narrowly paniculate, up to 16 cm long, many
flowered, tomentose; flowers in glomerules. Bracts lanceolate to subulate. Flowers (female unknown)
7-9 mm long, pubescent. Calyx 3.5 mm high. Stamens free, glabrous. Disk cupular, 2 mm high, fleshy,
densely erectly pilose. Pistil none. Infructescences unknown; calyx with remnants of a 6-lobed,
fimbriate disk. Fruits ellipsoid, subtrigonous in cross-section, 7-8.5 by 4.5-6 cm, densely tomentose
when young, glabrescent, scurfy; pyrene smooth, with 3 angle-ribs near the apex and often
a faint median rib on each of the lids; lids 4-5 mm thick. Seeds (3-)2-1 ; all cells irregular-shaped,
sterile ones slightly or not reduced. [from Flora Malesiana]

The wood is very soft. The abundant resin is used for caulking canoes. An edible oil is pressed
out of the seeds, which also are eaten.
