Nuevas localidades de tres helechos para la Península Ibérica.

In this work we include interesting chorological news regarding to three ferns which are unknown or scarce in the Iberian Peninsula. Firstly, it is documented for the first time the presence of Polystichum braunii in the Iberian Peninsula. On the other hand, we add the third known locality for the hybrid Asplenium × aran-tohanum. Finally, we extend notably the distribution of Struthiopteris spicant var. homophyllum towards the interior of the Iberian Peninsula. [ABSTRACT FROM AUTHOR]
