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 rugosa occurs on wooded slopes at high elevations in trans-Pecos Texas, southern New Mexico, and Arizona, and throughout most of the mesic montane parts of Mexico, south to Guatemala. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
