Summary:

The tribe Heliantheae is expanded to include the genera previously placed in the tribe Helenieae and many genera from the Senecioneae. Thirty-five subtribes are recognized and described, and the more than 265 genera are listed with known, validly described synonyms. A theoretical key to subtribes is provided. Various structural and chemical characteristics are reviewed, and emphasis is given to resin duct patterns, presence of fiber-sheaths in disk corollas, and patterns of striations in achenes. The Heliantheae is considered a member of the subfamily Asteroideae in a position parallel to and more advanced than the Eupatorieae.
