Did you check the labellum calli? The leaves in the first image are quite round so C. turfosa is a possibility. The general appearance of the plant in the second image looks more like valida.
Unfortunately I was a bit late for the season as most flowers were dead and closed so I couldn't see any calli. The habitat was certainly not at all boggy but definitely something to check out next season. It would be interesting to see C. turfosa.
