|discussion=<p><i>Quercus austrina</i> is probably the most misunderstood oak of the southeastern United States. Although the species is fairly widespread, it is apparently abundant only in local areas and is poorly represented in herbaria. This may be partly because <i>Q. austrina</i> is often misidentified as <i>Q. sinuata</i>, which it superficially resembles, or as <i>Q. nigra</i>, a red oak with similarly shaped leaves. It is easily distinguished from <i>Q. sinuata</i> by its larger, more acute buds; darker twigs; deeper, turbinate acorn cups; and absence of minute, appressed, stellate hairs on the abaxial leaf surface. Instead, <i>Q. austrina</i> has a tomentum of soft erect hairs on young leaves, and glabrate mature leaves.</p>
