Trees to 30 m tall. Branchlets of last year growth lenticellate; lenticels yellowish gray, ± raised. Petiole 1-1.5 cm, basally dark brown to blackish when dry; leaf blade narrowly oblong to lanceolate, 10-25 × 3-7 cm, thinly leathery, concolorous, abaxially glaucous and with adherent waxy scalelike trichomes, adaxial surface of young leaves glossy when dry, base cuneate to narrowly so, margin entire, apex narrowly attenuate with apiculate-caudate tip; secondary veins 11-15 on each side of midvein; tertiary veins abaxially visible. Male inflorescences solitary in leaf axils or congested at apex of branches; rachis pubescent. Female inflorescences solitary or congested; cupules in clusters of 3-5(-7). Infructescence rachis base 4-7 mm thick. Cupule turbinate to obconic, 2.5-3.5 × 2.5-3 cm, enclosing most of nut, apically usually flat; bracts conspicuous, imbricate and triangular or united into interrupted rings, appressed, from base to middle of cupule, densely tawny puberulent. Nut subglobose, ca. 3 × 2.6 cm, with tawny appressed minute hairs, apex ± flat or slightly convex, wall ca. 1 mm thick on sides and ca. 1.5 mm thick near apex; scar covering 2/3-4/5 of nut, convex.
