Asplenium auriculatum

A widespread Neotropical spleenwort with once-pinnate fronds whose pinnae carry a small ear (auricle) at the base, found from Mexico and the Caribbean to Bolivia and southern Brazil. It mostly grows on trunks and mossy rocks in humid lowland and lower-montane forest. Measured sites point to mild, evenly warm conditions with a wet season and a short, drier spell in the first months of the year.

Where it grows wild

Humid evergreen and lower-montane forest, typically on tree trunks, branches and mossy boulders in shade to dappled light. Habitat detail here is inferred from the genus and the spread of records, not from a species-specific account.

GBIF records run from sea level to about 2,500 m with a median of 1,360 m; the 5,250 m maximum is almost certainly a georeferencing error.
