Typical high-elevation populations in the Sierra Nevada of California can be distinguished from all shrubby forms of Quercus chrysolepis by the absence of glandular trichomes and by thin cups with small nut-attachment scars. At lower elevations in northern California and southwestern Oregon, secondary contact with Q. chrysolepis has resulted in the formation of hybrids.

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