Tree, up to 21 m, 23 cm dbh. Axillary buds inserted (1.5—)3—15 mm above the axils on 1-2 mm long stalks; scales elliptic to linear-lanceolate, 6-18 by 1.5-8 mm long, faintly nerved. Petiole 7-10 mm, glands present or not. Leaf-blade 8-14 by 2.5-5 cm; above often slightly bullate between the secondary nerves, mostly dark green, secondary nerves finely prominent to obscure, venation obscure to finely prominent; beneath glaucous-papillose, secondary nerves 6-8 pairs, forming a ± distinct intramarginal nerve; glands either not numerous, mostly situated near midrib, and c. 0.3 mm diam., or numerous, scattered, and 0.1-0.2 mm diam. Inflorescences shorter to much longer than the leaves, the lower branches distinctly supra-axillary, (sub)opposite; axes densely minutely hairy, more or less grooved, angular. Pedicel 1.5-2 mm, grooved, densely patently minutely hairy. Sepals glabrous inside except for a few hairs at the very base; outer sepals c. 2 by 2 mm; inner sepals c. 3.5 by 3 mm.
