Abstract
Two new species of Acritopappus, A. catolesensis D. J. N. Hind & Bautista and A. pintoi Bautista & D. J. N. Hind from the Chapada Diamantina, Bahia State, Brazil, are described and illustrated. The genus is predominantly from the campos rupestres of Bahia and Minas Gerais States, and 15 species are now recognized in Bahia. The first new species, because of its typical monopodial primary axis and decussate side branches and inflorescences, falls into a group of non-viscid leaved species. The second species, unique in the genus, is a distinctive tree, and has unusual leaf and inflorescence characters. The tree-like nature of the species in the genus is discussed relative to the terminology usually applied to many members of the Compositae found in Brazil.
