The circumscription of the genus Cheilanthes Sw. is supported by molecular and morphological characters; nevertheless, the taxonomic status of some species remains uncertain because they have not been molecularly tested yet. This study analyzes the belonging of Cheilanthes volcanensis de la Sota to this genus, since this species was treated with doubts about its generic identity. From a morphological approach, C. volcanensis is close to Cheilanthes species with pentagonal and highly divided leaf blades; petioles and rachises castaneous to black, glabrous, usually grooved adaxially; features that are also largely representative of the morphological circumscription of the genus Gaga Pryer, F.W. Li & Windham. The molecular analysis of a recent collection, identified a priori as C. volcanensis, demonstrated with high support that the species belongs to the genus Cheilanthes s. str., as was described originally. Finally, morpho-anatomical observations of this species and related species are also provided, which support its phylogenetic position and contribute to the correct generic delimitation of Cheilanthes s. str.
