摘要
Cheilanthes pantanalensis, a new species from the Brazilian Pantanal is described. A complete morphological description is presented, as well as illustrations and comments on the most similar species. This species is distinguished by its (2-)3-pinnate, leaves and by having ultimate segments that are ovate to suborbicular. We also report Cheilanthes hassleri and C. obducta as new records for Brazil, both from Mato Grosso do Sul.
