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.) |
Some of the specimens referred to Quercus endemica by C. H. Muller should be placed in Q. grisea. Numerous hybrids between Quercus grisea and other white oaks, including Q. gambelii, Q. mohriana, Q. arizonica, and numerous species in northern Mexico, have been reported. In the Hueco and Quitman mountains of trans-Pecos Texas, putative hybrids of Q. grisea × Q. turbinella Greene occur. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
