Although no hybrid combinations have been formally proposed, D. M. Hunt (1989) has reported evidence of hybridization with Quercus hemisphaerica, Q. incana, Q. myrtifolia, and Q. phellos. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
This species flowers one to two weeks earlier than Q. inopina (A. F. Johnson and W. G. Abrahamson 1982). Quercus myrtifolia reportedly hybridizes with Q. incana (= Q. ×oviedoensis Sargent), but E. J. Palmer (1948) questioned the identification of the type specimen; the brief description by Sargent suggests that the specimen may be from an individual of Q. inopina. D. M. Hunt (1989) cited evidence of hybridization with Q. arkansana, Q. hemisphaerica, Q. inopina, Q. laurifolia, Q. marilandica, Q. nigra, and Q. pumila (Hunt suggested that the last may give rise to occasional reports of annual fruiting in Q. myrtifolia).
