Adiantum pectinatum

A South American maidenhair recorded from Costa Rica and Colombia south to Bolivia, Paraguay, northern Argentina and Brazil, mostly at low to middle elevations (median 500 m). The measured sites have a warm summer and a noticeably cooler, less humid winter, so it is more tolerant of seasonal change than the equatorial lowland species.
