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).

Apparent hybridization between Quercus vaseyana and Q. pungens is discussed under the latter species.
