|discussion=<p>Plants from Florida (<i>Ageratum</i> littorale, the type from Florida) are described here. Plants of the West Indies and Mexico (broadening the species concept to <i>A. maritimum</i>, the type from Cuba) have various elaborations of vestiture and a more conspicuous pappus–coronas with even to laciniate margins or rings of nearly separate scales mostly 0.2–1.5 mm. In addition to the distinctive relatively small, glabrous or glabrate leaves, plants of <i>A. maritimum</i> are characterized by heads in clusters, usually held well beyond the leaves.</p>
