     Here it was that the Lastrea Fœnisecii was growing in such luxuriance; and in the very cave of which it was the gate keeper I found Wilson's Filmy-Fern, clothing the moist sides as a curtain.

     Parsley fern is plentiful on the higher hills, Wilson's filmy fern is common in sub-alpine glens, and moonwort, adder's tongue, hart's tongue and, very rarely, the royal fern are also to be got.
