So I’ve found a species of Dryopteris in forest in southern Hamburg. But I can’t find out if it’s D. dilatata, D. expansa or D. carthusiana. They look so similar to me! Is there any way to clearly differentiate them? What are the features I need to look out for?
Here is a video I did there: https://youtube.com/shorts/aa_wtmpoQrM?si=K2VLpdp3qogC4j38
