Cheilanthes pohliana is endemic to Brazil, occurring in the Amazon and Cerrado in the states of Goiás, Maranhão, Mato Grosso do Sul, Mato Grosso, Minas Gerais, Pará and Tocantins ( Ponce et al. 2023). In the study area, the specimens of C. pohliana were recorded in the cerrado rupestre, growing on rock formations among tree-shrubby vegetation.

It is characterized by the basally 2-pinnate frond that is once-pinnate distally, petioles and rachis cylindric, dark brown to black, with short hairs, and ovate-oblong pinnules with dense, pluricellular hairs on both sides.
