Adiantum calcareum

A small maidenhair of central Brazil, recorded from Goiás, the Federal District, Bahia, Minas Gerais and Mato Grosso. The name and records suggest shaded limestone outcrops and dry forest in the Cerrado region, where it faces a hard five-month dry season. Little is published on its ecology, so this profile relies on the measured climate and on what is known of Cerrado limestone ferns.
