Characteristics

Tree 20-30 m. Twigs robust, glabrous. Leaves ovate-oblong, gradually attenuate towards the apex, or obtusely acuminate, base broadly attenuate to nearly rounded, coriaceous, glabrous, shining on both faces, paler beneath, olivaceous when dry, entire, (10-)12-18 by (4-)5-7(-9) cm, midrib prominent on both sides, nerves in 8-10 pairs, arched, raised on both faces, veins ± transverse, forming a dense and prominent network with the veinlets on both sides; petiole stoutish, 12-15 mm. Racemes axillary, spiciform, rather robust, shortly fulvous-tomentose, 15-20 cm including the 1-2 cm long peduncle. Flowers scattered, with several ovate imbricate basal bracts 2-3 mm. Pedicels of the lower flowers 3-2 mm, shorter to very short below the upper flowers. Bracts fan-shaped or broadly obovate, glabrous inside, pubescent outside, ± 5 mm long, subpersistent. Bracteoles 2, at or near the apex of the pedicel, similar to but smaller than the bracts, subpersistent. Calyx tube obconical, densely yellowish-velutinous, 3 mm; sepals 9-10, linear, subobtuse, membranous and velutinous, c. 8 by 2 mm initially, much accrescent and becoming chartaceous in later stages, finally oblong-subspathulate, nerved, c. 18 by 3-4(-5) mm. Petals 9-10, oblong, subacute, velutinous, 5-6 by 2 mm at first, finally attaining c. 10 by 3 mm. Stamens 6, +-in pairs at and somewhat above the base of each petal, further 2 or 3 between each of the subglobose grey-tomentose glands; filaments slender, patent-pilose, 3-4 mm. Ovary white-tomentose, with 5-7 styles, these longhaired below, glabrous above.
