Adiantum abscissum

A Brazilian maidenhair fern of the Atlantic Forest and gallery forests of the interior, with over 300 wild records from Ceará south to Santa Catarina. Little is published on its ecology beyond herbarium labels, so this profile builds on the measured climate and on how lowland Brazilian Adiantum grow: warm, humid, shaded forest floor with a mild, drier winter.

Where it grows wild

Terrestrial in shaded, humid lowland and submontane forest, including Atlantic coastal forest and riverine forest in the cerrado belt. Like most Brazilian maidenhairs it likely favours well-drained banks and slopes rather than waterlogged ground.

Recorded from sea level to about 960 m, median 315 m (157 records).
