Asplenium ceterach
Fern. It is characterised by a short rhizome which gives rise to several green fronds that have a pinnated lamina with trichomes (hairs) on the lower surface, but not the upper one. These trichomes are orange-brown in colour, hence the name "rustyback". The petiole is shorter than the corpus of the leaf.
It likes growing in rocky walls. Spotted on a rock in Parque Nacional de Monfragüe.
