Where it grows wild

Treated here as a rock-crevice fern, as is typical of Asplenium hybrids in the Pyrenees and Iberia. The habitat of this particular hybrid was not described in the sources checked.

The two GBIF records sit at about 230 m and 1260 m. The name points to the Val d'Aran in the central Pyrenees.
