I was out orchid hunting today, and found a nice group of orchids. I'm not familiar with the species growing in the Netherlands, but I do know that it is some sort of Dactylorhiza. I'm thinking that it might be the Southern Marsh orchid, Dactylorhiza praetermissa. Looks a lot like it, they are found in the Netherlands, and I found these at the edge of a marsh. Or it could be a natural hybrid, since Dactylorhiza orchids hybridize quite easily.
Does anyone have an idea of what it might be?
