I usually find this distinctive fern high up in the mountains growing out from underneath a rock but here in the Pyrenees at a height probably greater than those Scottish hills, it was a roadside weed. This is a northern hemisphere fern which is found in Europe, mountainous north America and even as far north as Alaska and Greenland.
