Tree 25-30 m. Twigs 1.5-3 mm diameter, drying often ± 2-or 3-angled, grey or (blackish) brown, glabrescent, hairs grey-brown, 0.1 mm or less; older twigs blackish brown, coarsely longitudinally cracking and flaking; lenticels few, conspicuous or inconspicuous, or absent. Leaves chartaceous (to thinly coriaceous), oblong-lanceolate, 6-15 by 1.5-3.5 cm, gradually narrowed to the acute apex, base broadly attenuate or rounded; upper surface olivaceous or (dark) brown, dull, lower surface grey-brown or light brown, dull, early or late glabrescent, hairs ± dense, brownish, scale-like or stellate, 0.1 mm or less (lens!); not distinctly papillose; dots absent; midrib slender, flattish above, lateral nerves 16-21 per side, at 60-70° to the midrib, flat and very faint above, faint, not contrasting below, lines of interarching and venation indistinct; petiole proportionally long, (13-) 15-22 by 1.5-2 mm; leaf bud 10-15 by 1.5-2 mm, hairs grey(-brown), appressed, 0.1 mm or less. Inflorescences between and below the leaves, sometimes on the older wood, of the Knema-type, brachyblast sessile, short, simple, to 3 mm, densely rusty pubescent, with 5-15 flowers in a loose apical cluster, buds ± equal in size; flowers with dense dark brown hairs 0.1 mm. Male flowers (immature): pedicel slender, 3-5 mm, bracteole ovate or rounded, 1 mm, (sub)apical, persistent; buds ovoid to broadly ellipsoid, 3 by 2-2.2 mm, rounded at apex and base, cleft 1/3, lobes 1 mm long, 0.3 mm thick. Androecium broad-cylindrical, 2 mm; androphore 0.3 by 0.6 mm (to 1 mm long at anthesis), glabrous except for a few scattered pale hairs less than 0.1 mm; synandrium 1.7 by 0.7-0.8(-l) mm, thecae c. 15, sterile apex ± blunt or truncate, 0.1-0.2 mm. Female flowers (NGF 33391): pedicel straight, 4-5 by 1 mm, bracteole ovate, nearly 1 mm, subapical; buds ovoid, 4 by 3 mm, the apical part narrowed into a ± blunt apex, base broadly rounded, cleft 1/3, lobes 1.4 mm long; ovary long-ovoid, 2.2-2.5 by 1.8 mm, hairs dense, golden-brown, appressed, 0.2-0.3 mm. Fruits not seen, fructescences probably with several fruits, judged from the many-flowered female inflorescences.
