Upper canopy tree up to 43 m tall and 73 cm dbh. Stipules absent. Leaves
alternate, paripinnate, not pseudogemmulate, compound, leaf tips continuing to grow
indeterminately, leaflets penni-veined, up to 28 by 10.5 cm, glabrous to hairy below. Flowers
ca. 5 mm diameter, white-yellow, placed in panicles. Fruits ca. 24 mm diameter, red, capsules.
Seeds with aril.
Tree to 43 m, but often flowering when 2-3 m tall; bole to 20 m and 73 cm diam.,
sometimes fluted or buttressed, buttresses to 2 m tall, 1 m out and 8 cm thick, concave.
Bark pale greenish to black, smooth to faintly cracked, lenticellate, the lenticels in horizontal
rows (Pennington); inner bark pale to dark brown; wood pale to dirty cream,
often smelling of methyl mercaptan. Leafy shoots c. 6 mm diam., glabrous to deciduously
tomentose. bark dark, cicatrices conspicuous. Leaves to 70 cm, paripinnate to
pseudogemmulate, in terminal bunches; petiole 7-15 cm, glabrous to pubescent. Leaflets
6-28 by 2.5-10.5 cm, narrowly oblong to oblong- or elliptic-lanceolate, opposite
to subopposite, often maturing all together, thinly coriaceous, often conspicuously paler
abaxially, base c. rounded or rarely subcordate, c. unequal, shortly acuminate, adaxial
surface glabrous or with tomentose midrib and pubescent veins, abaxial surface glabrous
or with tomentose midrib and pubescent veins, abaxial surface glabrous to softly
tawny pubescent, midrib and veins tomentose, costae 9-14 on each side, +/- prominent
abaxially, tertiary venation often conspicuous; petiolules 3-6 mm. Thyrse to 90 cm,
borne in upper axils or supra-axillary, pendent, paniculiform; most proximal branches
to 17 cm (10 cm in females), ultimate branchlets cymules of subsessile or shortly pedicellate
fragrant flowers; axes glabrous to tomentose; bracteoles minute. Calyx 2.5-3
mm, cupular to shortly tubular, puberulous, margin subentire to minutely, irregularly
toothed. Petals 4, 5-10 mm long, subspathulate-elliptic, glabrous to glabrescent. Staminal
tube 5-7(-8) mm, glabrescent or minutely pubescent near mouth without, pubescent,
tomentellous or very rarely villous within, margin with (5-)6-8 linear-triangular
lobes a little shorter than anthers; anthers (5-)6 or 7(-8), basifixed, glabrous, locellate.
Disk absent or very short, fleshy, glabrous, +/- lobed. Ovary pubescent; style glabrous
to densely short pubescent; stylehead cylindric to clavate. Capsule to 5 cm long, 4.5 cm
diam., subglobose, stipilate, glabrous to tomentose (especially when unripe), 2-locular;
stipe to 2 cm. Seeds 2, 5-11 mm long, to 8 mm wide, scutiform, half covered by an aril.
[from Flora Malesiana]
In undisturbed mixed dipterocarp forests up to 500 m altitude, however,
seems to prefer open places. On hillsides and ridges, but also common along
rivers. On sandy to clay soils, but also on limestone.
The wood is locally used in house building.
