--><p>A molecular phylogenetic study of tribe Hydrangeeae (Y. De Smet et al. 2015) found <i>Hydrangea</i> to be polyphyletic. The authors promoted adoption of a broader, monophyletic concept of <i>Hydrangea</i> that includes all eight genera in the tribe, including <i>Decumaria</i>. <i>Decumaria</i> is treated here in its traditional sense.</p>
