Beautiful dressed in green Arabic source in the Partal Gardens of the Palacios Nazaries of the Alhambra in Granada. It is very striking the tendency of this fern to live in sources. (Double click on the photo to enlarge)
Another ancient fountain built during the Muslim domination of Mallorca, located in the village of Randa, in a fertile valley at the foot of a small mountain in the center of the island. The ferns have their roots anchored in the thick layer of moss.
Irrigation canal collects water from the previous source, locally called Font de Randa, with a large colony of Adiantum capillus-veneris. Mallorca Arabs who built the fountain and the irrigation canals more than 8 centuries dominated the art of using water. It is only fair to acknowledge the great legacy left to those who expelled them from their beloved island. With the near certainty to take a little blood in my veins arrears of almost 3,000 descendants of the Moors Mallorcan left as slaves in their own land and were forced to be baptized, I dedicate this article in appreciation of the immense work done by converting a dry and unproductive island in an orchard.

Adiantum capillus-veneris between the stones of a bank of a banana of Tazacorte on the Canary island of La Palma.
Fine specimen of Adiantum capillus-veneris with deeply lobed pinnae growing on the rocks bordering the Torrent de Pareis of Sa Calobra on the northwest coast of Mallorca.
Typical pinnae of black maidenhair fern. Each pinna is divided into several pinnules separated by a notch. Picture taken in a garden of Mallorcan town of Sóller.
Underside of the pinnae of the previous photo with immature sori covered by a false membranaceous indusium, pseudoindusium, inserted at the edge of the pinnules.
Mature sori, one on each pinnules, with raised pseudoindusium exposing the sporangia, which are already being deployed and dispersed the spores. Shows the lattice structure of the pinnae fan-shaped, typical of the genus Adiantum.
Microscopic photograph of a sporangium of Adiantum capillus-veneris, now empty after the dispersal of spores. You can see the torn bag containing the spores.
