This looks to be a Pyramidal Orchid (Anacamptis pyramidalis), rather more bulbous than pyramidal in full flower.

  A "common" orchid though that is a relative concept where orchids are concerned. I see A. pyramidalis often enough in its favoured habitat of chalk grassland. But I was surprised to see this specimen on the margin of the fallow field I wrote about in my last entry.

 They can't survive repeated ploughing and spraying but this one was close to what remained of the hedgerow.
