Dryopteris Filix-mas

Dryopteris filix-mas (male fern) is a common fern of the temperate Northern Hemisphere, native to much of Europe, Asia, and North America. It favours damp shaded areas in the understory of woodlands, but also shady places on hedge-banks, rocks, and screes. It is much less abundant in North America than in Europe. The plant is sometimes referred to in ancient literature as worm fern.
