Leaves evergreen, leathery, to 11 × 4.5 cm, ovate to elliptic or lanceolate, rounded at the base, tapering to a slender point at the apex, margin edged with slender, pointed teeth, often only towards the apex, or entire; sparsely hairy when young, particularly on the veins beneath, becoming glossy green above, paler beneath, and glabrous by the second year. Up to 12 pairs of veins either side of the midrib. Petiole glabrous, to 2 cm long. Infructescence short, 2 cm or less, bearing 1 or 2 cupules.

Two small plants at Arboretum des Pouyouleix, France, were raised from seed collected by Josef Soucek in China in 2013. With a southern distribution at low elevations, Quercus setulosa has not performed well there. The surviving plants have been cut back during winter and several others have died. It might be better in a milder location (B. Chassé pers. comm. 2020).
Described in 1923, the epithet means ‘with little bristles’ (from Latin setula = small bristle, coarse hair), in reference to the leaf margin.
