Tree 5-15(-30?) m. Twigs 2-3 mm diameter, at first with rusty hairs 0.3-0.6 mm long, glabrescent; bark striate or in Sulawesi and Seram (partly) sometimes faintly striate, not tending to crack or flake. Leaves chartaceous, elliptic, subobovate, or (ob)lance-olate, 7-26 by 2-7.5 cm, apex acute(-acuminate), rarely subtruncate, base attenuate to rounded, drying (greenish) brown above, lower surface grey-glaucous, at first with hairs of mixed size, 0.3-0.6 mm long, largely glabrescent, with some indumentum remaining on or near the midrib and nerves, finely papillate, with hair scars; dots absent; midrib raised above; nerves 16-26 pairs, raised above; venation very distinct; petiole 10-20 by 1.5-3.5 mm. Inflorescences: sessile, brachyblast simple or bifurcate, to 10 mm long; in male 2-15-flowered, female 1-5-flowered; flowers with rusty woolly hairs (0.2-)0.3-l mm long; perianth 3-lobed, reddish (?) inside. Male flowers: pedicel 2-5 mm long, brac-teole late caducous, (sub)apical; buds broadly obovoid or globose, 2.5-3 mm diameter, cleft nearly to the base, lobes 0.5-0.7 mm thick; staminal disc flat, circular, 1—1.5(—2) mm diameter; anthers 6—9(—11), stiped, horizontal or slightly oblique, 0.3-0.5 mm long, spaced; androphore slender, 0.7-1 mm long. Female flowers: pedicel 2-4 mm long, bracteole subapical; buds obovoid-oblong, 4.5-6 mm long, cleft c. 1/2, lobes 0.5 mm thick; ovary ovoid, 1.5-2 mm long, stigma subsessile, 2-lobed and each lobe again 2-5-lobulate. Fruits 1-3 per infructescence, obovoid, pear-shaped, or ellipsoid, apex obtuse or shortly beaked, (1-) 1.5-2.5 by (0.8-) 1-1.8 cm, with harsh rusty hairs 0.5 mm long; dry pericarp 1.5-2 mm thick; fruiting pedicel 2-5 mm long.
