Tree 6-8(-30, see note 1) m. Twigs terete or faintly angular, (2-)3-4 mm diameter, early glabrescent, hairs greyish, less than 0.1 mm; older twigs coarsely striate (but neither cracking nor flaking), with inconspicuous small brown lenticels. Leaves chartaceous or subcoriaceous, oblong-lanceolate, 14—18(—23) by 4-6(-6.5) cm, base attenuate or narrowly rounded, apex acute-acuminate; upper surface dark brown, lower surface grey-brown, early glabrescent, hairs scattered, less than 0.1 mm; not papillose; dots present, sometimes only few; midrib flat or raised above, lateral nerves 20-30 per side, at 70-80° to the midrib, flat and inconspicuous above, hardly visible below, lines of interarching and venation indistinct; petiole 10-20 by 2-2.5 mm; leaf bud 10 by 2 mm, hairs less than 0.1 mm. Inflorescences among the leaves and below, of the Knema-type: sessile, scar-covered, subglabrous, brachyblasts to 5 mm diameter; bracts 1.5 mm, hairs rough, 0.2 mm, caducous; in male: a subumbel of 2-4 flowers, buds of slightly variable size; female inflorescences (from the infructescences, see note 1) few-flowered, similar to male; flowers with ± scattered hairs less than 0.1 mm. Male flowers: pedicel 3-4 by 1-1.5 mm, bracteole large, deeply cucullate, 8-9 by 6 mm, with short-fimbriate margin, at first completely enveloping the perianth, caducous; buds (slightly immature) coriaceous, ovoid-ellipsoid, 8 by (5-)6 mm, apex rounded or subacute, base rounded, cleft c. 1/3, lobes 2(-2.5) mm long, 0.5-0.6 mm thick. Androecium ± stout, 7 mm; androphore l(-2) by 2 mm, glabrous; synandrium broad-cylindrical, 6 by 2.5(-3) mm, narrowed to the apex, thecae c. 40, narrow and tightly contiguous, sterile apex minute, 0.1 mm. Female flowers not seen. Infructescence just below the leaves. Fruits (LAE 61173) (somewhat immature) solitary, sessile, coarsely wrinkled, ovoid-ellipsoid, 4 by 2.5 cm, apex narrowly rounded and with short pointed style-remnant, base narrowed into a short pseudostalk 3 mm, hairs rather pale grey-brown, scale-like, 0.1 mm or less; pericarp 5-7 mm thick, with faintly warted surface; seeds not seen; fruiting pedicel 10 by 5 mm, with few fissures and lenticels, bracteole scar 4 mm below the apex.
