|discussion=<p>The vegetative stems of <i>Euphorbia ipecacuanhae</i> are often quite short in proportion to the dichasial or pleiochasial branches, thus superficially plants often appear to have mostly opposite leaves. However, careful examination of the base of the plant will reveal alternate leaves. The leaves are extremely variable in both shape and coloration, and the variation can be pronounced within a population or even on a single plant. M. J. Huft (1979) did not recognize infraspecific taxa within <i>E. ipecacuanhae</i>, and his treatment is followed here. This species is found on the Atlantic coastal plain.</p>
