STAUDT, Mariana Guerra  e  ROQUE, Nádia. The Vernonieae and Eupatorieae tribes (Asteraceae) from Morro do Chapéu, Bahia, Brazil. Rodriguésia [online]. 2020, vol.71, e00402018.  Epub 17-Abr-2020. ISSN 2175-7860.  http://dx.doi.org/10.1590/2175-7860202071016.

Studies dealing with the floristic composition of the Espinhaço Range corroborate the impressive diversity of Asteraceae, especially Eupatorieae and Vernonieae, which are the tribes with the largest number of species. The aim of this study was to carry out a floristic and taxonomic survey of the species belonging to the Vernonieae and Eupatorieae tribes which occur in Morro do Chapéu, Chapada Diamantina, Bahia. Six field trips were conducted and the main herbaria with the most important Chapada Diamantina collections were visited. Tribe Vernonieae is represented by 13 genera and 28 species. Lepidaploa (6 spp.) entails the highest number of species, followed by Stilpnopappus and Vernonanthura with four species each. For tribe Eupatorieae we found 17 genera and 30 species. Acritopappus and Mikania, with six and five species respectively, represent the richest genera, followed by Trichogonia (3 spp.). The species Acritopappus jacobaeus, Acritopappus santosii, Lapidia apicifolia, Scherya bahiensis, Stylotrichium edmundoi, Trichogonia tombadorensis and a new species belonging to the genus Stilpnopappus, are endemic to the Morro do Chapéu municipality. Keys to genera and species identification, descriptions, taxonomic comments and examined materials for all species are presented, as well as images.
