TAXONOMY:
The scientific name of Oregon white oak is Quercus garryana Dougl. (Fagaceae) [40,62,64,70]. As the common name suggests, Oregon white oak belongs to the white oak subgenus (Lepidobalanus) [143].

Infrataxa:
Quercus garryana var. breweri (Engelm.) Jepson [70], Brewer's oak
Quercus garryana var. garryana
Quercus garryana var. semota (Jepson) [47,70], Oregon white oak

Hybrids:
Quercus × eplingii C. H. Muller [47,62,101,106,144], Epling's oak (Oregon white oak × blue oak (Q. douglasii))
Quercus × howelii Tucker [101,143,144], Howell's oak (Oregon white oak × Nuttall's scrub oak (Q. dumosa))
Quercus × subconvexa Tucker [40,62,101,143,144] (Oregon white oak × leather oak (Q. durata))

Brewer's oak hybridizes with deer oak (Q. sadleriana) [62,144].

Quercus garryana var. garryana hybridizes with scrub oak (Q. berberidifolia) [62] and valley oak (Q. lobata) [62,144]. There may be introgression of Q. garryana var. semota and valley oak in isolated locations of distribution overlap [40].

According to Govaerts and Frodin [47], Q. × subconvexa and Howell's oak describe the same hybrid―Oregon white oak × Nuttall's scrub oak.
