Seen in forest in Spanish Basque country at 400 meters alt.
The second picture is from underneath the leaves
No interactions present.
Thanks for your help. It sounds ok and I am changing the name of the observation
There is no other Blechnum species recorded from Europe (says Flora Europaea).
You don't need to add another identification line if you agree with the one someone else has given - just click on 'I agree' rather than putting in a new one. :)
