The capillary of the walls or doradille polytric ( Asplenium trichomanes ) is a small fern of the family of the Aspleniaceae .

The sling S are divided only once, the Pétiole is brown dark with black.

It pushes on the walls like in the cracks of rock, very seldom with the sun. This is why one finds it in the most strange hollows pushing on a very fine layer of very black topsoil. Very often on Calcareous support . It is extremely resistant to the Dessication and cold. The Altitude does not fear (1500 with 1800m). It can be cultivated out of pot but by observing all the conditions which it knows in its natural environments. It is common in France.
