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).
