It is unlikely that this particular species grows in any of these locations which are mostly tropical. Hart's Tongue Fern (Asplenium scolopendrium) is a temperate species which grows in Europe with a rare variety Native in the northeast US. I was shown a population which was growing under an old mill in a MD state park in Darlington at the mouth of the Susquehanna River as it enters the north end of the Chesapeake Bay. The American variety is less likely to grow on a man made structure so this was probably the European variety. Nobody crawled into the opening to positively ID it.
Asplenium scolopendrium is fairly common in nurseries locally, and has thrived here in zone 9b. Native to Europe.

The plant pictured dropped out of the sky one day and just missed me by a foot. It had been dislodged by the workmen removing the chimney. It was promptly planted in it's new position and has grown happily ever since.

Hart's Tongue fern survived well through our hot, dry summer. It got lots of water, plenty of shade, and rich, loamy soil.
