Description:Genus Description - The genus Eupatorium L. has been the subject of much taxonomic attention in the last two decades, resulting in the segregation of scores of genera out of Eupatorium as traditionally defined. King and Robinson (1987) thoroughly summarized the taxonomy of the tribe Eupatorieae and their work has already proven to be one of the most useful recent treatments on the Compositae. By leaf, involucral, and pappus features, many ofthe 180 genera in the 18 subtribes that they recognize are markedly distinct (e.g., Monogerion Barroso & King, Planaltoa Taubert, Chromolaena D C , Pseudobrickellia King & H. Robinson), whereas some genera with opposite leaves, persistent phyllaries, and many pappus bristles seem not to be as well defined. Thus, it is conceivable that the number of recognized genera eventually may dwindle. (It should be noted, however, that while the genera of the subtribe Praxelinae seem distinct, Eitenia polyseta King Robinson.)
