|discussion=<p><i>Euphorbia dentata</i> is native from northern Mexico and the south central United States north and east through the Ohio River Valley. Scattered occurrences in the southeastern United States likely represent adventive populations. Reports of <i>E. dentata</i> as a noxious weed (from the United States and the Old World) should most likely be attributed to introductions of <i>E. davidii</i>.</p>
