Asteraceae from the Municipality of Mucugê, Bahia, Brazil

Floristic surveys of the Asteraceae in the Espinhaço Range have showed a significant species richness and endemisms in this family for the grassland vegetation. Thus, this study aims to survey the floristic inventory of the Asteraceae in the municipality of Mucugê, Bahia, providing subsidies for an updated taxonomic recognition of the family in the region. Field collections have been conducted for at least a decade and a half covering much of the area. We also analyzed the material from the herbaria ALCB, CEPEC, HRB, HUEFS, MBM, NYBG, RB, SP, SPF and UB. Asteraceae is represented in Mucugê by 18 tribes, 78 genera and 167 species. The tribes with the greatest number of species are Eupatorieae (49 spp.), Vernonieae (46 spp.), Astereae (18 spp.) and Heliantheae (11 spp.). Five of the genera are monospecific (Pseudostifftia, Platypodanthera, Bahianthus, Conocliniopsis e Prolobus) and five are endemic to Bahia (Pseudostifftia, Stylotrichium, Lasiolaena and Semiria). The genera with highest number of species are Baccharis (17 spp.), Lychnophora (11 spp.), Mikania (10 spp.), Lepidaploa and Lessingianthus (7 spp.) each. Identification keys to the tribes, genera and species, followed by taxonomic comments and geographic distribution for each taxon, and illustrations and images are presented.
