Trees up to 25(-50) m high, dbh up to 75 cm, with up to 6 m high buttresses; bark usually smooth and reddish (sometimes greyish) brown. Branchlets terete, 4-8 mm in diam., redbrown to cinnamon or purplish black, smooth to slightly grooved, lenticels inconspicuous, the tip appressed short fulvous hairy, otherwise glabrous. Leaves often with 2 buds, mostly only the lower one developing; petiole terete or sometimes slightly flattened above, smooth or (thicker ones) canaliculate, strongly swollen at base, 5-25 cm long, 1.5-3 mm thick; rachis slightly flattened above, otherwise terete, sometimes cannate above towards the apex; petiolules terete, above with a narrow groove, 3-7.5 mm long, mostly slender. Leaflets elliptic (to ovate), (5-)10-15(-40) by (2.5-)3-5(-10) cm, index 2-4, the upper often, sometimes all slightly falcate, chartaceous, often with a naked gland in or in front of some of the nerve axils beneath; base rounded and attenuate to acute; apex (obtuse or) tapering (rarely rather abruptly) short to rather long broadly (rarely slender) obtuse-to acute-acuminate, mucronate or not; midrib slender, above prominu-lous to sunken, beneath mostly sharp-triangular, sometimes ± rounded, nerves l-2(-4) cm apart, angle to midrib 55-75°, slightly, towards the margin strongly curved, mostly free but for the uppermost ones, sometimes a few looped and joined towards the margin, prominulous above, more so beneath, intercalary veins variable, mostly feeble, veins and veinlets reticulate, above mostly faint, beneath prominulous. Inflorescences thyrsoid to co-rymbiform, up to 30 cm long, densely and minutely appressed brown hairy; branches sparsely branched; cymules with stalks to 1 cm long and up to c. 25-flowered; bracts triangular and hardly 0.5 mm to subulate and 3 mm; pedicels slender, 3-4 mm long, slightly thickening towards the apex. Flowers copper. Calyx in male flowers c. 3 mm high, 2 mm in diam., the opening c. 1 mm in diam., lobes minute; in female flowers 1.5-2 mm high, 3-4 mm in diam., the opening wider than in male, lobes broad-triangular, c. 0.8 mm high. Petals in male flowers elliptic, c. 1 by 0.6 mm, in female subovate, 1.5 by 1.5 mm. Stamens: filaments c. 1 by 0.2 mm; anthers c. 0.3 mm; stamens in female flowers hardly reduced. Pistil c. 1.5 mm high; stigma-lobes triangular, dorso-ventrally flattened, c. 1 mm long. Fruit parts 3-4(-5) by 2-2.5 cm, green to brown, the Warts pyramidal to triangular, up to 2 mm long, pericarp c. 0.8 mm thick, endocarp smooth, white. Seeds ellipsoid-ovoid, 2.5 by 1.7 cm, testa smooth, shining dark brown, arillode to 6-10 mm high.

A tropical plant. They occur from Luzon to Mindanao in primary forests at low altitudes in the Philippines. In Indonesia it grows up to 600 m altitude.

Uses The whitish to light reddish brown timber is used for indoor construction. The arillode is edible; the cooked or roasted seeds are eaten and are said to be comparable with but more delicious than Castanea seeds. See Brown Useful Pl. Philipp. 2 1950 357 f. 174 Heyne Nutt.
