Discussion | Quercus pagoda is often treated as a variety of Q. falcata; it is quite distinctive, however, both morphologically and ecologically (S. A. Ware 1967; R. J. Jensen 1989). This species reportedly hybridizes with Q. falcata and Q. phellos (D. M. Hunt 1989). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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).
