Taxonomic novelties in Mikania (Asteraceae: Eupatorieae) from Atlantic Forest, Brazil

During studies of Brazilian Atlantic Forest Asteraceae, a new species and a replacement name were determined: Mikania amorimii from Bahia State and Mikania capixaba from Espírito Santo State. The former is a new species related to M. ternata but distinct by its leaves, involucral bracts and cypsela morphology. The latter is proposed as a replacement name for Mikania dentata G.M.Barroso, a later homonym of M. dentata Spreng. Line drawings and comments about conservation status are made for both species.
