Trees having acorns with broad, distinctly warty cups are sometimes classified as Quercus coccinea var. tuberculata Sargent. Quercus coccinea reportedly hybridizes with Q. imbricaria, Q. ilicifolia (= Q. ×robbinsii Trelease), Q. laevis, and Q. palustris (E. J. Palmer 1948) and with Q. phellos, Q. rubra, and Q. velutina (= Q. ×fontana Laughlin). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Quercus ilicifolia reportedly hybridizes with Q. coccinea, Q. falcata, Q. imbricaria, Q. marilandica, Q. phellos, Q. rubra, and Q. velutina. The Iroquois considered Quercus ilicifolia very helpful in treating gynecological problems (D. E. Moerman 1986). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
