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 sadleriana is one of the most distinctive western oaks, with strong similarities to certain eastern North American and Asian species of Quercus with "chestnut" leaves. Its restricted distribution in the Siskiyou region and uncertain relationships suggest it is a relictual species. It hybridizes occasionally with Q. garryana var. breweri (see treatment).
