N.B. reporting of the edit history is currently fairly unclear and misleading. Most edits made to specimens appear as a pair of 'add' and 'delete' entries, which may not be together in the list. There are also often 'minor' edits, which are made automatically (rather than due to user activity), for example to merge synonym names.

on review, one of the R G Benson herbarium specimens?

[David Price]

A presumed derivative of Dryopteris affinis x D. expansa, formerly found at Loch Lomond and Galway, this taxon is now extinct in the British Isles.

The note "Chatford form" does not necessarily mean that this specimen was collected at Chatford.

Hi

Many thanks, I am now better informed, but what is the answer to my question?


regards

I'm fairly sure this is not a Dryopteris at all, but Polystichum aculeatum.
