what taxon is this? see 'notes' above.

Dryopteris remota (A. Braun ex Doll) Druce (the presumed derivative of D. affinis x D. expansa) grew in Co. Galway and near Loch Lomond and is now extinct.

Lastrea remota Moore was first observed at Windermere (see Clowes in Phytologist (1860) p.227), is discussed at length and illustrated in English Botany 3 ed. and is what this specimen would seem to be. Contemporary opinion inclined to the view that it is a hybrid of D. filix-mas.
