I think we might have to agree to differ on this one Mike, although I should add that I'm only looking at a 2" BlackBerry screen.
I see three pointers to BLH:-
Hairy ovaries
No groove between bosses (but yes, they do look clean!)
Ants, I often see them after the nectar on BLH but not on GFH
I'm happy to be proved wrong, or convinced so.

Hi Alan
Some extremely good points, and I am tending to agree with you....but with caveats.
I agree the lip looks helleborine-like in terms of the bosses. The ants are an excellent and novel pointer, too - I'll remember that one!
I do think the hairy ovaries might be an artefact created by camera shake in the close-up. I'm struggling to see that as a feature whilst viewing on my laptop.
Looking again at the close-up, it is clear that completely intact pollinia are visible on at least two flowers, one of which is otherwise almost gone over. This would go strongly against it being phyllanthes, and very much towards it being helleborine. I wonder if it also may indicate hybrid origin....perhaps any scent/colour attractive to wasps, that helleborine puts out, is confused and they have therefore avoided the plant? It is unusual in my experience to see a long-open E. helleborine which has not been visited at all by wasps.
The leaf structure looks better for helleborine, too.
I would be inclined towards this plant being viridiflora/chlorantha Broad-leaved helleborine, but with the possibility that it is indeed a hybrid (this would be the first proven record for England, and only the second for Europe that I know of, as it preceeds the Hampshire one which was found in 2010).
Rich - I know you have given me the site name, perhaps you could email me some more specific directions, as I am headed that way this week? I would be interested to check the site out. More pics and maybe send them to John Richards for an opinion? Mark Lynes would be interested, too, no doubt.
All the best
