Notes: Many taxonomic and nomenclatural changes have occurred within Asteraceae since the publication of Hitchcock and Cronquist (1973). The Flora of North America project(FNA) published the Asteraceae volumes in 2007, and that has served as the primary literature resource for the taxonomy and nomenclature provided here. Some of the introduced taxa in Washington belonging to this family are not included in the FNA volumes. Many of these can be found in Stace's New Flora of the British Isles (1997). Ken Chambers and Scott Sundberg provided a treatment of the Asteraceae for the Oregon Flora Project (OFP), and some of their taxonomic decisions are followed here rather than what is provided in FNA.
