Ned it is very hard to tell P. sphacelatum and P. tadgellianum apart by the flower but one feature often referred to is the state of the leaf at time of flowering with P. sphacelatum observed to being withered at flowering where P. tadgellianum is observed as remaining green well after flowering. Your photos show the leaf as still green. It is quite possible these are P. tadgellianum. That growing in clumps is also similar to my finds for P. tadgellianum. I find the reference to the lateral sepals being fused or free not always reliable.

Hi Derek,
I was definitely a bit uncertain of my id with this one as leek orchids are quite hard to tell apart. The plants were noticeably taller than P. tadgellianum seen on the same walk and the tips of the leaves are withered (you can just make it out in the third photo) which I think is seen in P. sphacelatum but possibly also P. tadgellianum. They were growing in the water of a bog if that helps id. I trust your expertise though and your experience in leek orchids.
