--><span class="statement" id="st-undefined" data-properties=""><b>Trees,</b> deciduous, to 15 m. <b>Bark</b> almost black, with irregular or rectangular blocks, inner bark orangish. <b>Twigs</b> ashy brown, (1-)2-4(-5) mm diam., pubescent to tomentose. <b>Terminal</b> buds conic or narrowly ovoid-ellipsoid, 5-10 mm, noticeably 5-angled in cross section, tawny pubescent. <b>Leaves</b>: petiole 5-20 mm, densely to sparsely pubescent. <b>Leaf</b> blade obovate to obtrullate, (50-)70-200 × (40-)70-200 mm, base rounded or cordate, blade not decurrent, margins with 3-5 shallow, often very broad lobes and 3-10 awns, apex acute to obtuse, rarely rounded; surfaces abaxially scurfy or with scattered pubescence, adaxially glossy, glabrous, secondary veins raised on both surfaces. <b>Acorns</b> biennial; cup turbinate, 6-10 mm high × 13-18 mm wide, covering 1/3 nut, outer surface puberulent, inner surface pubescent, scale tips loose, especially at margin of cup, acute or acuminate; nut broadly ovoid or ellipsoid, 12-20 × 10-18 mm, often striate, glabrate, scar diam. 5-8 mm. <b>2n</b> = 12. [R. C. <b>Friesner</b> 1930. J. W. <b>Duffield</b> (1940) suggested that Friesner was counting bivalents; if so, then 2n = 24, consistent with all other reports for <i>Quercus</i>.]</span><!--

|discussion=<p>Evidence suggests that small trees from the western portion of the range (primarily Texas and Oklahoma) should be recognized as <i>Quercus marilandica</i> Münchhausen var. ashei Sudworth (D. M. Hunt 1989). These trees are characterized by 50-70 × 40-60 mm leaf blades with abaxial surfaces gray-tomentose in vein axils.</p><!--
--><p><i>Quercus marilandica</i> reportedly hybridizes with <i>Q. buckleyi</i> and <i>Q. falcata</i> (E. J. Palmer 1948); and with <i>Q. georgiana</i>, <i>Q. ilicifolia</i> (= Q. ×brittoni W. T. Davis), <i>Q. imbricaria</i> [= Q. ×tridentata (A. de Candolle) Engelmann], <i>Q. incana</i>, <i>Q. nigra</i>, <i>Q. phellos</i> (Q. ×rudkini Britton), and <i>Q. velutina</i> (= Q. ×bushii Sargent). D. M. Hunt (1989) cited evidence of hybridization also with <i>Q. arkansana</i>, <i>Q. hemisphaerica</i>, <i>Q. laevis</i>, <i>Q. laurifolia</i>, <i>Q. myrtifolia</i>, <i>Q. palustris</i>, and <i>Q. rubra</i>.</p><!--
--><p>The Choctaw used <i>Quercus marilandica</i> to ease cramps and to aid in childbirth (D. E. Moerman 1986).</p>
