The much narrower circumscription of Thelypteris adopted by Fawcett & Smith requires most of our existing Thelypteris identifications to be bumped up to Thelypteridoideae so as not to conflict with identifications of the new segregate genera.

Identification
ID 2 of taxon E will be an unintended disagreement with ID 1 of taxon B after the taxon swap
If thinning a parent results in more than 10 unintended disagreements, you
should split the parent after swapping the child to replace existing IDs
of the parent (B) with IDs that don't disagree.
Thanks for doing this!
