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.

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).
