2001
Nordenstam (1977) listed 100 genera in his systematic review of Senecioneae, but Bremer’s (1994) recent synthesis suggests 120. Even more recently, Nordenstam (1996) lists 123. The reason for the generic increase in the tribe stems mainly from segregates being pulled out of Senecio in a fashion similar to what has happened to Vernonia.

GENERIC BOUNDARIES IN THE SENECIONEAE
TAXON, 1985SummarySince the time of Bentham the traditional view of the Senecioneae has been that of one huge genus (Senecio) plus numerous segregate genera of varying degrees of distinctiveness, plus a few entities of uncertain affinities. Data have accumulated to support the exclusion of some genera from the tribe (e.g.

The identity of Cremanthodium citriflorum (Asteraceae, Senecioneae)
Phytotaxa, 2017Our critical observations of herbarium specimens (including type material) and living plants demonstrate that Cremanthodium citriflorum is identical to C. delavayi and that the holotype sheet of C. farreri is a mixture of C. delavayi and C. farreri. We therefore place C. citriflorum in synonymy with C. delavayi. We recognize C.

A Checklist of the Brazilian Senecioneae (Compositae)
Kew Bulletin, 1993The family Compositae is generally recognised as one of, if not the, largest of the families of flowering plants in the world with an estimated 25,000 species (effrey 1978) in about 1500 genera (effrey, pers. comm.). Roughly half are from the New World and are centred in Central and South America.
