落叶乔木，高达30米，树皮黑褐色，纵裂。小枝较细，径约1.5毫米。叶片宽披针形至卵状披针形，长7-12厘米，宽2-3.5厘米，顶端渐尖，基部圆形或宽楔形，略偏斜，叶缘具刺芒状锯齿，幼时被黄色柔毛，以后两面无毛，或仅背面脉腋有柔毛，侧脉每边12-16条；叶柄长0.5-1.5厘米。雄花序长4厘米，花序轴被柔毛。壳斗杯形，包着坚果约1/3，径约1.5厘米，高约0.8厘米，壳斗上部的小苞片线形，长约5毫米，直伸或反曲；中部以下的小苞片为长三角形，长约3毫米，紧贴壳斗壁，被细柔毛。坚果椭圆形，直径1.3-1.5厘米，高1.5-2.5厘米，顶端有微毛；果脐微突起，径约5毫米。花期3-4月，果期翌年9-10月。
产江苏、安徽、浙江、江西、福建、河南、湖北、四川等省。生于海拔600米以下的丘陵地区，成小片纯林或与其它落叶阔叶树组成混交林。
木材为环孔材，边材淡红色，心材浅褐色，气干密度0.816克/立方厘米；栎实含淀粉63.1％，单宁7.8％，蛋白质5.8％。

Quercus chenii Nakai
小叶栎 xiao ye li
Quercus acutissima Carruthers subsp. chenii (Nakai) A. Camus; Q. acutissima var. brevipetiolata G. Hoo; Q. acutissima var. chenii (Nakai) Menitsky; Q. chenii var. linanensis M. C. Liu & X. L. Shen.
Trees to 30 m tall, deciduous. First-year branchlets ca. 1.5 mm thick. Petiole 0.5-1.5 cm; leaf blade broadly lanceolate to ovate-lanceolate, 7-12 × 2-3.5 cm, yellowish brown tomentose, glabrescent or only veins abaxially tomentose at axils, base shortly attenuate to broadly cuneate and slightly oblique, margin with spiniform teeth, apex acuminate; secondary veins 12-16 on each side of midvein; tertiary veins abaxially inconspicuous. Cupule cupular, ca. 8 mm × 1.5 cm including bracts, enclosing ca. 1/3 of nut; bracts from base to middle triangular, adherent to cupule, tomentose, ca. 3 mm, apical bracts linear, ca. 5 mm, rectiserial or inflexed. Nut ellipsoid, 1.5-2.5 × 1.3-1.5 cm, apex pale brown sericeous; scar ca. 5 mm in diam., slightly raised, stylopodium ca. 2 mm in diam., pale brown sericeous. Fl. Apr, fr. Oct of following year.
* Mixed mesophytic forests; below 600 m. Anhui, Fujian, Henan, Hubei, Hunan, Jiangsu, Jiangxi, Shandong, Sichuan, Zhejiang
Very closely related to Quercus acutissima, and could just represent the small extreme of that species.
