Resumo

Nomenclatural and taxonomic notes are provided as the result of a taxonomic revision of Baccharis subgen. Tarchonanthoides, currently underway. A list of accepted species within the subgenus, their synonyms, and a revised sectional classification are presented. Protologues and types of previously published names have been reviewed. Currently 21 species and 10 synonyms are recognized within the subgenus. Morphologically, the species of the subgenus are classified into four sections: Canescentes (9 spp.), Coridifoliae (8 spp.), Curitybensis (2 spp.), and Tarchonanthoides (2 spp.). A new combination and status is proposed to B. coridifolia subsp. bicolor, B. uleana is assigned to subgen. Tarchonanthoides, and lectotypes are designated for B. artemisioides, B. curitybensis, B. erigeroides var. dusenii, B. gibertii, B. patens, B. psammophila and B. squarrosa, most of them providing `second-step' lectotypes.
