Quercus marilandica (L.) Münchh.

Comments ( 英語 )

由eFloras提供
Evidence suggests that small trees from the western portion of the range (primarily Texas and Oklahoma) should be recognized as Quercus marilandica 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.

Quercus marilandica reportedly hybridizes with Q . buckleyi and Q . falcata (E. J. Palmer 1948); and with Q . georgiana , Q . ilicifolia (= Q . × brittoni W. T. Davis), Q . imbricaria [= Q . × tridentata (A. de Candolle) Engelmann], Q . incana , Q . nigra , Q . phellos ( Q . × rudkini Britton), and Q . velutina (= Q . × bushii Sargent). D. M. Hunt (1989) cited evidence of hybridization also with Q . arkansana , Q . hemisphaerica , Q . laevis , Q . laurifolia , Q . myrtifolia , Q . palustris , and Q . rubra .

The Choctaw used Quercus marilandica to ease cramps and to aid in childbirth (D. E. Moerman 1986).

Acorns 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. 2 n = 12.
