Latin for 'large flowers'.
Tree up to 40 m by 60-70 cm, without buttresses. Branchlets 0.5-1 cm diam., rusty-tomentose; pith
with a peripheral cylinder of scattered vascular strands. Stipules subpersistent, inserted on the
petiole at 0.25-0.75(-3) cm from its base, 6-8 by 10-20 mm, deeply 3-4-lobed, stiff, densely and
minutely fulvous-tomentose. Leaves (3-)4-5-jugate. Leaflets obovate, lanceolate or oblong, 9-20 by
4.5-8.5 cm, coriaceous, glabrescent; base oblique, cuneate to cordate; margin entire; apex gradually to
abruptly, shortly and slenderly acute-acuminate; nerves (10-)13-19 pairs (angle 60-70 degrees), faintly
curved, abruptly, usually distinctly, arching close to the margin. Inflorescences pseudoterminal to
terminal, terminal ones broadly and laxly paniculate, 25 cm long female, main branches up to 9 cm,
with few flowers; pseudoterminal ones narrowly paniculate, 25-30 cm long male, main branches
6-11 cm, paniculate, c. 10-flowered; minutely tomentose. Flowers pubescent, male 11 mm, female 13-15
mm. Calyx broadly cupular, male 7 mm, female 9 mm. Corolla female pubescent at both sides, male inside
glabrous. Stamens adnate to the disk, filaments glabrous. Disk glabrous, male saucer-shaped, 1 mm
high, rim undulate; female cupular, 2.5-3 mm high, truncate. Pistil long-pilose; male none.
Infructescences c. 25 cm long, sparsely tomentose, with 4-5 fruits; calyx saucer-shaped, 3-lobed,
2-2.5 cm diam. Fruits ellipsoid, sometimes acute, bluntly triangular in cross-section, 5-5.5 by
3.5-4 cm, sparsely, near the apex densely, ferrugineously tomentose; pyrene smooth with 3, blunt to
acute, angle-ribs, specially near the apex; lids 1-2 mm thick. Seed 1, spindle-shaped, acuminate at
base, 4 by l.5 cm; fertile cell in cross-section circular, 1.5 cm diam., sterile cells strongly
reduced, without lumen. [from Flora Malesiana]
In undisturbed mixed dipterocarp forests up to 400 m altitude. On hillsides
and ridges with sandy soils, occasionally on limestone.
The wood is said to be hard. In Brunei this species is cultivated for its edible seeds which
are among the largest of this genus. The resin is said to be abundant.
