|discussion=<p>The taxonomic history of <i>Euphorbia pubentissima</i> is complex. The species has been included within a very broadly defined <i>E. corollata</i> in the past. Therefore, its geographic distribution appears significantly more wide-ranging in some treatments. The framework established by M. J. Huft (1979) and later by K. R. Park (1998) is followed here. <i>Euphorbia pubentissima</i> is recognized as a variable species restricted to the southeastern United States. The species can be distinguished from <i>E. corollata</i> by its shorter involucral gland appendages and smaller seeds. <i>Euphorbia</i> paniculata Elliott, which sometimes is applied to <i>E. pubentissima</i>, is an illegitimate name (a later homonym of <i>Euphorbia</i> paniculata Desfontaines).</p>
