Eutrochium Rafinesque. Joe-Pye-weed.

Key to Eutrochium

A genus of 5 species, perennial herbs, of North America. The separation of Eutrochium (Eupatoriadelphus) from Eupatorium was supported by Schmidt & Schilling (2000). Lamont (2004) made the necessary combinations under the oldest available generic name, Eutrochium Rafinesque. The widely used common name for the genus is discussed at detail by Pearce & Pringle (2017), who conclude that it relates to an 18th century native American in Massachusetts, named Joseph Shauquethqueat.
