The joe-pye weeds were classified as Eupatoriums, until recently, when plants in the genus were separated into several new ones (Ageratina, Chromolaena, Conoclinium, Eutrochium, Fleischmannia, Hebeclinium, Koanophyllon, Tamaulipa).
Maybe we should repeat something like what we did with the Asters, Dave? Merge
The Joe Pye Weed Database with
The Eupatoriums Database and lump in the genera listed above?
