Although originally published by Alphonse Pyramus de Candolle as "wislizeni",<ref name="de Candolle"/> some sources{{sfn|Flora of North America}} mistakenly spelled the [[Botanical name|specific epithet]] "wislizenii". Correct spelling is with one "I", per ICN article 60C.2.<ref>J. McMeill et al. (eds). 2012. International Code of Nomenclature for algae, fungi, and plants. Regnum Vegetabile 154. Koeltz Scientific Books. {{ISBN|978-3-87429-425-6}}</ref> [[Friedrich Adolph Wislizenus]]'s specimen was thought by de Candolle to have been collected in [[Chihuahua (state)|Chihuahua]], Mexico. German-born American botanist [[Georg Engelmann]] later corrected the location to the American fork of the Sacramento River near [[Auburn, California]].

California physician and botanist (and one of the founding fathers of the California Academy of Sciences) [[Albert Kellogg]] described an oak in an 1855 publication as ''Quercus arcoglandis'' (spur acorn oak),<ref>Kellogg, Proc. Calif. Acad. 1(1):25 (1855)</ref> apparently the same species as ''Q.&nbsp;wislizeni''. This clearly predates French-Swiss botanist de Candolle's 1864 name, and if confirmed to be this same taxon would have priority.

Currently there are two recognized varieties of interior live oak:{{sfn|Jepson eFlora: ''Quercus wislizeni''}}
* ''Q. wislizeni'' A. DC. var. ''wislizeni'' (1864)
* ''Q. wislizeni'' A. DC. var. ''frutescens'' Engelm (1878).<ref>Engelm., Trans. Acad. Sci. St. Louis 3:396 (1878).</ref> This is an invalid taxon. Engelmann's ''Q.&nbsp;wislizeni'' var. ''frutescens'' description is virtually identical to de Candolle's ''Q.&nbsp;wislizeni,'' while Engelmann's ''Q.&nbsp;wislizeni'' description most closely matches Kellogg's ''Q.&nbsp;morehus''.<ref name=Keuter>{{cite journal|author=Duncan A.
