Senecioneae is the biggest Tribe of the Asteraceae (Nordestam 1996), comprising 150 genera (more than 9 % of all genera) and 3,500 species (about 15 % of all species of the Family) (Nordenstam 2007). The circumscription of many Senecioneae genera has changed, especially Senecio L., with about 1,250 species (Bremer 1994; Frodin 2004; Nordenstam 2007). To Brazilian Senecioneae, Hind (1993a) estimated the occurrence of 97 species belonging to eight genera, and the more useful works to identify them are Cabrera (1950, 1957), Cabrera and Klein (1975), Robinson (1980), Hind (1993a; 1993b; 1994; 1999), and Teles et al. (2006).
