Steve that looks like ssp coccinea but i am just a novice,Dactylorhiza's are a nightmare,me and FredG have scratched our heads loads of times looking at them in the field.I think the problem were i live, is that a lot of the nature reserves are ex colliery sites so the imported top soil comes from everywhere and anywhere so all of a sudden more than one sp pops up ,then hybridisation follows and head scratching begins.I hope this makes sense and might be wrong but its how i see it.
