Asplenium auritum

Eared spleenwort

A widespread tropical spleenwort, the eared spleenwort, found from Florida and Mexico through Central America and the Caribbean to southern Brazil and northern Argentina, and also in eastern and southern Africa, Madagascar and the Mascarenes. It grows mainly as an epiphyte, on trunks and branches in moist forest from the lowlands into the mountains, and sometimes on rocks. It suits a warm, humid terrarium or a shaded, humid greenhouse.

Where it grows wild

Mainly epiphytic on trunks and branches, sometimes on rocks, in humid forest: riverine and gallery forest, flooded forest along lagoons and streams, and montane forest. GBIF labels include gallery and riparian forest, hillside forest and secondary forest.

GBIF elevations run from 5 to about 3500 m, with a median around 1060 m (195 records in a sample of 300); most plants grow between the lowlands and about 2000 m.
