I cannot confirm the species, since the plants had already flowered and the seed pods were ripe. However, they seem Pinguicula vulgaris. I also found some Pinguicula in the Cereceda valley, but did not take any pic.
Once more I have to thank J.S.F. (Hall of Fame member), M.P.O. and R.N.G. for their patience, for stopping the car in the middle of the road and for their cameras. Although they have helped me in similar situations. They still aren't carnivorous plants fans :-(
Enjoy the pics!

General view of a colony. Pinguicula and some ferns grow on nearly bare rock. Plants were only present in wet rocks, with a constant water flow. Many of them grow in a hard muddy crust over the rock wall.
Plant with some small insects and debris.
