|discussion=<p><i>Euphorbia pinetorum</i> has a restricted distribution in southern peninsular Florida, primarily in Miami-Dade and Monroe counties. The species is very similar to narrow-leaved forms of the closely related <i>E. cyathophora</i> but differs in its perennial habit, consistently unlobed leaves, and purpurescent involucral glands and cyathia.</p>
