| Description: Perennial fern with an erect or ascending rhizome and fronds of to 60 cm of length. The stalk, of the half of long to as long as the leaves, is of purple brown colour to a large extent of its length and with brown paleae. It is covered with glands, especially in the nerves, more densely by the back side than by the face and that give it certain smell to hay. The lower pinna is asymmetric, since the basescopic proximal pinnula is more developed than the acroscopic corresponding. The pinnulae have triangular lanceolate forms and the proximal have the abruptly made thin and obtuse apex, with the revolute margin; the segments of last order are lanceolate or triangulate - lanceolate, of obtuse apex and with the margin with sharp, dispersed and edged teeth. The sores appear in the back side, they have paraphysis, and they are protected by a small, thin and glandulous indusium, of invalid, flat, whitish colour. |

Distribution: It appears in Azores, Madeira, Canaries, the NW and SW of France,
reaching the NE of Turkey and some localities in the United
Kingdom. In the Peninsula appears of relictus form in the
Cantabrian coast until reaching for the W Galicia.

Habitat: This rare fern lives in zones of acid character, quartzites chiefly,
of little permeable substrate with a strong superficial overflow
that often show processes of tubification. It appears in tempered
hilly zones. Its optimum environment are closed and protected
valleys or narrow torrents, near the sea, with high atmospheric
humidity and growing on quartzite or sand. It is a differential
plant of communities which belong to the subalianza Hyperico
androsaemi.
