|discussion=<p><i>Euphorbia lasiocarpa</i> is similar to <i>E. hypericifolia</i> but is much more hairy on its stems and leaves. <i>Euphorbia lasiocarpa</i> is widespread throughout tropical America, but its precise native range in the New World is not clear. In the flora area, <i>E. lasiocarpa</i> is found in southern Florida, where it is likely introduced.</p>
