Following up on this theme, Ponce & Scataglini (2020) described the new genus Mineirella to accommodate four species previously considered to belong to Cheilanthes , but now known to be more closely related to Adiantopsis and Doryopteris . Mineirella differs from typical Cheilanthes by having creeping rhizomes and pentagonal, pedate, lobate-pinnatifid, bipinnatifid, or basally pinnate leaves. The genus occurs on the sandstone and basaltic substrates in central Brazil and extends into Paraguay and Bolivia , where we find one species.
