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.) |
Material from Texas and northeastern Mexico, excluding the type, has been incorrectly referred to Quercus glaucoides M. Martens & Galeotti by some authors (K. C. Nixon and C. H. Muller 1992). On the Edwards Plateau of Texas, Quercus laceyi occurs mostly at 350-600 m elevation; in Coahuila and Nuevo León, it occurs at 1500-2200 m. This species is sometimes associated with remnant mesic forests, which include Acer grandidentatum Nuttall, Tilia species, Quercus muhlenbergii Engelmann, and various pine and other oak species. The leaves are shallowly lobed or entire, although occasional specimens on moist sites are deeply lobed and resemble the leaves of Q. alba in outline.
