Gymnocarpium robertianum is found in limestone habitats in eastern North America, Europe, and the Caucasus mountains. The dense glandular hairs present on the leaves help to distinguish it from G. dryopteris which otherwise looks similar.

Nice photos! It is great to see all these cool European species on FOTW.
I really want to visit a good limestone area in North America before going back to Brazil…
