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.) |
Quercus emoryi reportedly hybridizes with Q. graciliformis (= Q. ×tharpii C. H. Muller). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
