It is a Pteris of the P. biaurita group (where the bases of the ultimate segments are quite widely joined, so that the inter-pinnular sinus is quite a bit above the pinna-costa).

I have tried hard to see the venation between the segment-bases - as it is essential in this group.  Photo 1 - I think? - seems to show that there is a narrow areole all along next to the costa, with veins arising from it and passing up to the sinus.   If that is so then it is P. biaurita subsp. fornicata.

    If it is possible to get the herbarium-specimen and make a close-up photo of the bases of a couple of segments against the light, we could then see the identity for sure.

    Could you do that and repost it?  Or otherwise can you send me a higher-resolution image of photo 1, so I can magnify it enough to see those essential veins?

Well it's pretty much the same - by the time it reaches me it goes out of focus when one magnifies it enough to see the venation.  But you have a look and see if you can see what I think I am seeing - a very narrow areole formed by the anastomosing basal veinlets, the areole running along the pinna-costa?  Is that right?  So I thinkit's  just P. biaurita subsp. fornicata, which is a triploid-apomictic subspecies of P. biaurita - a very common and widespread species.

Best wishes,

Chris Fraser-Jenkins, Portugal.
