Leaf-blade circular or broadly ovate-elliptic, widest near or proximal to middle, 100-200 × 80-150 mm, base attenuate to acute, occasionally obtuse or rounded, blade decurrent on petiole, margins with 3-7 (-9) lobes and 7-20 awns, lobes attenuate to falcate, occasionally oblong or distally expanded, apex acute to acuminate; surfaces abaxially occasionally orange-scurfy, usually glabrous except for conspicuous axillary tufts of tomentum, adaxially glabrous, secondary-veins raised on both surfaces. Acorns biennial; cup somewhat goblet-shaped, 9-14 mm high × 16-24 mm wide, covering 1/3 nut, outer surface puberulent, inner surface pubescent, scales occasionally tuberculate, tips loose, especially at margin of cup, acute, margin conspicuously involute; nut ovoid to broadly ellipsoid, 17-28 × 12-18 mm, often faintly striate, glabrate, scar diam. 6-10 mm.

Discussion

Quercus laevis reportedly hybridizes with Q. falcata (= Q. ×blufftonensis Trelease), Q. hemisphaerica, Q. incana, and Q. marilandica (C. S. Sargent 1918); with Q. nigra; and with Q. arkansana, Q. coccinea, Q. myrtifolia, Q. phellos, Q. shumardii, and Q. velutina (D. M. Hunt 1989).
