🇬🇧 Likely the most abundant and most photogenic occurence of this plant in the Hradčany Walls, on the most exposed SW edge of the top of the rock.

I do assume this is Dryopteris remota upon the leaves' shape and darkened stipe base of pinnae.

erwin_pteridophilosDescription
Since i took so many photos of this unusual fern, it's all but easy to select just a few to show here. I was surprised and delighted to see the fern growing abundantly in the cracks of the serpentine rocks. So this is a most important population at the border of the species' native range. This site is surely something very special, at least in Austria.

erwin_pteridophilosDescription
The main population of the rare fern is located within the protected NSG Gurhofgraben, where it grows in large numbers upon the serpentine rocks. I could find just a few scattered examples upon rocks to the NE of the NSG (Naturschutz-Gebiet), N of the Mitterbach. The unusual fern is strictly protected by the law, apart of that one could not separate these plants from the substrate without destroying them, and these ferns had no chance to survive.
