Resumo
Senecio stricto sensu has about 1,000 species distributed predominantly in mountainous areas of the world. This genus is particularly diverse in South America, where are found about 500 species. In Brazil, Senecio s. s. is represented by 61 species distributed predominatly in damp or swampy fields altitude of the South and Southeastern regions. The taxonomy of Senecio s. s. species occurring in Brazil is unclear and need increments, since the most comprehensive studies of the Brazilian species are outdated, especially due to the addition of new taxa and du to changes in the circumscription of the genus. This study presents a taxonomic treatment of the species of Senecio s. s. occurring in the Rio de Janeiro State of which was based on survey of literature, bimonthly collections and consultation of herbarium materials (BHCB, ESA, HB, NY, R, RB, SP, UFG and VIC). Were recorded fourteen species, two of them (S. bonariensis and S. juergensii) are new records for the state of Rio de Janeiro showing that floristic inventories in the state are still needed. A historical revision to the genus, a key to species occurring in Rio de Janeiro, as well as descriptions with taxonomic comments, geographic distribution and illustrations for them all are given.
