Description

Tree or sometimes shrub, to 20m tall; young branches shortly golden-strigose, slightly striate. Petiole 1-2.5 cm long, stout, striate, canaliculate, short-strigose, soon glabrescent; blades coriaceous, oblong to lanceolate-oblong or elliptic-oblong, 12-30 x 4-13 cm, shining and olive-brown to golden-brown above when dried, silvery- or golden-sericeous or sparsely puberulous and soon glabrescent beneath, margins revolute, apex acute or acuminate, acumen 2-4 cm long, base acute, rarely obtuse or rounded; primary vein sulcate above, strongly prominent and striate beneath, secondary veins 7-10 on each side, slightly impressed above, prominent beneath, veinlets prominulous on both sides. Inflorescence to 6 cm long, densely golden strigose, becoming glabrous and stout in fruit; pedicels about 1 mm long; bracts and bracteoles ovate, densely pubescent, 0.5-2 mm long. Calyx glabrescent, 0.5 mm long; petals oblong-elliptic, 2-3 mm long, cream, glabrous except the inside of the inflexed apex; functional stamens to 4 mm long, the anthers 0.7 mm long, in pistillate flowers much smaller; disk eccentric, to 1 mm high, surrounding one half of ovary; functional pistil in female flowers slightly 5-angular or nearly cylindric, about 3 mm long, stigma capitate, rugose, in male flowers ovary abortive, rarely to 1 mm long, completely surrounded by fleshy disk.
