Characteristics

Tree 7-25(-30) m. Twigs 2-6 mm diameter, (late) glabrescent, hairs dense, woolly, golden or rust-coloured, 1-2 mm; older twigs grey-brown or blackish, finely longitudinally cracking, often thinly flaking; lenticels not apparent. Leaves chartaceous or (thinly) coriaceous, ovate-elliptic (rarely obovate-elliptic) to oblong-lanceolate, 10-32(-42) by 2.5—14(—18) cm, base shortly cuneate to narrowly or broadly rounded, or shallowly cordate, apex acute-acuminate; upper surface yellowish-olivaceous or brown, lower surface grey-brown or glaucous, indumentum persistent, or late or early glabrescent (in subsp. entrecasteauxensis), hairs dense, light brown, 0.2-0.3 mm, with a varying amount of scattered dendroid or almost unbranched shaggy hairs up to 1.5 mm; not or indistinctly papillose; dots absent; midrib raised above, glabrescent, lateral nerves 10-23 per side, at (50-)60-80° to the midrib, flat or sunken above (leaves in subsp. chrysophylla ± bullate), lines of interarching generally distinct, venation reticulate, ± indistinct; petiole short, 5-12 by 2-5 mm, late glabrescent as the twig apices; leaf bud 5—10(—15) by 3-4 mm, acute or blunt, hairs (1-)1.5 mm. Inflorescences as in Knema: sessile, simple or 2-fid scar-covered wart-like or vermiform brachyblasts; in male to 10 mm, late glabrescent or hairs persistent, woolly, 1 mm; flowers in clusters of 3-15, buds almost similar in size; bracts (late) caducous, 2 mm, pubescent; female inflorescences shorter, few-flowered; flowers with dense woolly yellow-brown hairs 0.5-1.5 mm. Male flowers: pedicel 1-2 by 1-1.5 mm, bracteole 2-3 mm, persistent; buds ovoid-oblong or nearly tubiform, 5-8 by 2.5-3 mm, apex blunt, cleft 1/4-1/3, lobes 1.5-2 mm long, 0.2 mm thick. Androecium slender, 4-5 mm; androphore about as long as or slightly shorter than the synandrium, l-3(-4) by 0.4 mm, towards the base with dense yellow-brown straight hairs 0.5-1 mm; synandrium 2-2.2 by 0.4-0.5 mm, thecae 8-12, sterile apex 0.2-0.3 mm. Female flowers: pedicel 0.5(-l) mm; buds ± ovoid, 5-6 by 4.5-5 mm, cleft c. 1/3, lobes 1.5-2 mm, at anthesis curved outwards; ovary broadly ovoid or subglobose, 2-2.5 mm diameter, hairs dense, woolly, pale brown, 1 mm, style 1 mm long, stigma 1 mm long, 2-or 3-lobulate. Infructescences much reduced. Fruits subsessile, solitary or 2 (or 3) together, subglobose or ovoid, 2-2.5 cm diameter, or ovoid-oblong, up to 4.5 cm, apex rounded or narrowed, hairs conspicuous, yellow-brown, dense, woolly, 2-4(-5) mm; pericarp 2 mm thick; seeds ellipsoid, 1.5-2.5 cm; fruiting pedicel 1-3 mm.
