|discussion=<p>Shrubs with oval leaves 25-38 mm and margins entire or deeply lobed-dentate may be treated as <i>Quercus wislizenii</i> var. frutescens. J. M. Tucker (1993) treated Q. parvula as a distinct species, distinguished from <i>Q. wislizenii</i> by its larger leaves (30-90 versus 20-50 mm), by the dull, olive-green, abaxial leaf surface (versus shiny, yellow-green), and by nuts that are abruptly tapered proximal to the middle (versus gradually tapered).</p><!--
--><p>Tucker recognized two varieties of <i>Quercus</i> parvula: Q. parvula <i></i></i>var.<i><i> parvula</i> is a shrub of 1-3 m and Q. parvula var. shrevei is a tree less than 17 m. S. K. Langer (1993) recognized a third variety, Q. parvula var. tamalpaisensis,based on several small populations on or near Mount Tamalpais, differentiated primarily by having larger leaves (50-160 × 20-60 mm) with attenuate-dentate margins.</p><!--
--><p><i>Quercus wislizenii</i> reportedly hybridizes with <i>Q. agrifolia</i> and <i>Q. kelloggii</i> (W. B. Brophy and D. R. Parnell 1974).</p>
