Lithocarpus celebicus Rehder

Tree 10-33 m, 30-100 cm ø; buttresses up to 1 m tall and out; bark grey-brown, fissured to scaly. Branchlets initially densely yellowish brown to rufous short stellate hairy, later glabrous, grey-brown, finely fissured, sparsely lenticellate; terminal buds ovoid, 3-5 by 2-3 mm, scales narrowly ovate-acute, densely tomentose by adpressed stellate hairs. Stipules linear-acute, 3-4 by ½-1 mm. Leaves thin-coriaceous, (8-)12-16(-20) by (3-)4-6(-8) cm (index (2-)½-3(-3½)), broadest at or below the middle; surfaces discolorous, above greyish brown, dull to glossy, sparsely pubescent, glabrescent, beneath with a thin cover of yellowish brown to greyish adpressed, minute, stellate hairs, on the midrib and nerves sometimes also with some erect stellate hairs; base rounded-acute to cuneate, decurrent, occasionally asymmetrical, top abruptly or gradually ½-2 cm acuminate, tip blunt or sharp; midrib thin, prominent on both sides; nerves (6-)8-10(-12) pairs, flat on both surfaces, subparallel, at an angle of 40-50°, arcuating but not anastomosing towards the margin; reticulation fine, subscalariform, lax, obscure; petiole subglabrous, ½-1 cm, 2 mm ø, adaxially flat or furrowed. Inflorescence male, androgynous or mixed, densely fulvous stellate hairy; bracts and bracteoles ovate-acute, 1-1½ by ⅔-1 mm. Male rachis 10-20 cm, 1-1½ mm ø; ♂ flowers in clusters of 3, filaments 3-4 mm, anthers 0.3-0.35 mm long, pistillode globose, 1 mm ø. Androgynous or mixed rachis 10-15 cm, 1-2 mm ø; female flowers solitary, very rarely in clusters of 2-3, staminodes rudimentary, styles 3, terete, 1½-2 mm, recurved. Ripe cupule sessile to ½ cm stalked, cup-shaped, ⅔-1 cm long, 2-3 cm ø; rim thin, covering c. ¼ part of the fruit; wall woody, thin, inside densely fulvous tomentose by adpressed simple hairs, outside densely yellowish brown stellate hairy; scales ovate, adpressed, rather distinct but not free, in concentric rows or imbricate. Ripe fruit ovoid-conical, 2-2½ cm long, 1⅔-2⅓ cm ø, glabrous, chocolate-brown, top rounded-acute, rarely ro-tundate-apiculate, base rotundate, scar deeply concave, 1-1½ cm ø; wall woody, 2 mm thick, for the greater part free from the cupule; cotyledons flat-convex.

Forests, at 20-1200 m, commonly below 800 m, on clayey soil. Fl. Sept.-May, fr. June-April. In New Guinea usually as co-dominant forming an association with species of Anisoptera (Dipt.) and Eugenia (Myrt.).
