Trees; bud scales, young shoots, petioles, leaf blades abaxially, and rachis of inflorescences densely covered with brown to reddish brown, slightly rough long tomentum. Petiole 1-3(-5) mm, usually tapering toward apex; leaf blade oblong, lanceolate, or oblanceolate-oblong, 9-18 × 3-7 cm, leathery, abaxially reddish brown when young but grayish brown to grayish with age, base cordate, shallowly auriculate, or rarely rounded, margin entire and revolute, apex acute, mucronate, or rarely rounded; midvein adaxially prominently impressed; secondary veins 14-18 on each side of midvein or fewer.
