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.) |
Of conservation concern. Since its original discovery in 1940 in Oglethorpe County, Georgia, Quercus oglethorpensis has been found to be more common locally near the type site in Georgia and South Carolina than originally thought. It remains one of the least-known oak species of the southeastern United States. Quercus oglethorpensis is one of our most distinctive eastern oaks, easily recognized by its narrow, entire, abaxially felty leaves.
