Dryopteris

 

a genus of ferns of the family Aspidiaceae. There are about 150 species, distributed in the temperate zone of Eurasia and North America and, to a lesser extent, in the tropical regions of Asia, Africa, and South America. The USSR has about 15 species. Especially widely distributed is the male fern (D. filix-mas). D. carthusiana (formerly D. spinulosa) is found in damp, mossy forests of the European USSR, the Caucasus, and Siberia. Both species are used medicinally as anthelmintics. D. fragrans grows on cliffs and slopes of the northern European USSR, in Siberia, and in the Far East; D. cristata grows in humid regions and swamps in the European USSR and Western Siberia.

And of course there are a great range of ferns that also love damp in the ground, such as Dryopteris filix-mas, the male fern with its beautiful shuttlecock-like tufts of fresh green fronds, Osmunda regalis, the royal fern, that turns reddish brown in autumn and Athryium felix-femina, lady fern with its lacy fronds.
Their species, a lot of them being pteridophytes (Polystichum lonchitis, Criptogramma crispa, Dryopteris filix-mas, Polystichum aculeatum), live in the holes of the blocks, ecology related with the Quaternary glaciation centred between Trevelez's Hills (eastern), and Caballo's peak (western).
Our common fern, Dryopteris filix-mas, although rather coarse in appearance, is exceptionally hardy and looks particularly good growing from a rocky crevice while the evergreen Asplenium adiantum-nigrum is a fine plant all year round.
