Hi Alexander

It looks to me like a nice plant of E.helleborine, if somewhat pale. There is no hint of any colouration of foliage to suggest E.purpurata and the flowers are not right. I suspect far too robust for E.phyllanthes, also the white viscidium is obvious which should rule it out.

As far as the lip is concerned, it tends to change and "bend under" as the flower matures exactly as you suggest.

All the best
