Abstract

Praxelis scaturicola, a new Cerrado biome species, is described and illustrated. The main morphological features of this new species are: i) capitula usually isolated; ii) vinaceous involucral bracts; iii) reduced glabrous leaves well-spaced on the stem. This study also presents information on aspects of the new species' habitat, as well as field images and illustrations. Praxelis scaturicola is known only from the Paraúna municipality in Goiás state, Brazil. A key and comments on the Brazilian species of Praxelis are also presented with a special note on the status of P. grandiflora. Additionally, the synonymy of P. macrocarpa under P. capillaris is proposed.
