The genus includes all the purple-flowering North American species of the genus Eupatorium as traditionally defined.[2] Eupatorium has recently undergone some revision and has been broken up into smaller genera.[3][4] Eutrochium is the senior synonym of Eupatoriadelphus.[5][6] Eupatorium in the revised sense (about 42 species of white-flowered plants from the temperate Northern hemisphere) is apparently a close relative of Eutrochium. Another difference between Eutrochium and Eupatorium is that the former has mostly whorled leaves and the latter mostly opposite ones.[6][7] Eupatorium and Eutrochium are both placed in the subtribe Eupatoriinae, but South American plants which have sometimes been placed in that subtribe, such as Stomatanthes, seem to belong elsewhere in the tribe Eupatorieae.[4]

Medicinal
A peer-reviewed study suggests that Joe Pye of plant fame was a Mohican sachem named Schauquethqueat who lived in the mission town of Stockbridge, Massachusetts from c. 1740 to c. 1785 and who took as his Christian name, Joseph Pye.[10] Other sources (although without citation) claim the plant was used to treat typhus outbreaks[11] and the treatment of kidney stones and other urinary tract ailments.[12]
