Common Polypody
(Polypodium vulgare) is common on walls, rocks and trunks. It's showing sori wich are yellowish or brownish clusters of sporangia on the edge or underside of a fertile frond. We found that on a wall near Barranco de Diazas. Taken while descending Miradores del Molar (2008 m) on January 25th, 2008.
