Where it grows wild

Known from about 95 wild records in the McPherson and Border Ranges area. The exact microhabitat (rock, soil or tree) was not confirmed from a reachable source; most Asplenium here grow on shaded rock or in moist forest. Care values are built from the measured climate and what is typical for the genus, because no species-level habitat text was reachable.

Records run from 265 to 1200 m, median 1000 m (30 records with elevation).
