I found a patch of what I believe are Southern Marsh Orchids at the railway tunnel entrance at Monsal Head. I'm not an expert at distinguishing the difference between the rarer northern species and the more widespread southern versions of these orchids. Monsal Head lies at the boundary between the northern and southern ranges of these two species in Derbyshire.
I have pre-posted all this week as I'm on my summer vacation, camping and Kayaking in Norfork. I'll catch up with AM3 when I'm back.
