Is this fern a Nephrolepis?

I found this fern in a local garden centre amongst their “Hardy Ferns”. It was labelled “Varens”, which is I believe Dutch for Fern. The label stated that it is suitable for indoor or outdoor use. I think it may well be Nephrolepis Exaltata ‘Green Lady’ which isn’t suitable for outdoors. What do you think?

Irish Fern ID Please

Please can you help me identify this fern.
Given as a present from County Cavan in Ireland.
It is growing now in chalky soil in Hampshire. Still green in January.
The fronds are scally, up to 60cm long and quite hardy, though the pinnae are quite fine & delicate. No sign of any sori on the back.

Parablechnum novae-zelandiae v P. wattsii

There is some confusion about Parablechnum novae-zelandiae and Parablechnum wattsii but in fact they are easy to distinguish

Parablechnum novae-zelandiae lowest pinna are very small and almost circular whereas Parablechnum wattsii lowest pinna are only slightly smaller than the next set of pinna
There are other differences but they require the observer to be able to compare the fronds
Parablechnum wattsii has a tougher more leathery fronds which are deep green and fairly flat, one-dimensional
Parablechnum novae-zelandiae has less tough fronds which are a lighter green and a bit undulating
Both these plants are dimorphic and here I am describing the infertile fronds
Both these plants used to be called Blechnums
