The leaves of these plants look spotted. I thought that both Northern and Southern Marsh-orchids didn't have spotted leaves. Although I've just noticed what is probably common spotted orchid to the left at the bottom of the photo, so maybe it's the leaves of those mixed in that's confusing.
A hybrid of Northern Marsh-orchid and Common Spotted would have spotted leaves and would explain the lobing of the labellum which should be triangular in NM.
Interesting, thanks for that info cicuta58.
