Discussion
Native Americans used Quercus falcata in various ways to treat indigestion, chronic dysentery, sores, chapped skin, chills and fevers, lost voice, asthma, milky urine, and as an antiseptic, a tonic, and an emetic (D. E. Moerman 1986).
Quercus falcata reportedly hybridizes with Q. ilicifolia (= Q. ×caesariensis Moldenke), Q. imbricaria, Q. incana, Q. laevis, Q. laurifolia (= Q. ×beaumontiana Sargent), and Q. marilandica (E. J. Palmer 1948); with Q. nigra, and Q. pagoda (S. A. Ware 1967; R. J. Jensen 1989); and with Q. phellos, Q. shumardii, Q. hemisphaerica, and Q. velutina.
