Some Dactylorhiza will be difficult to identify because each species varies and hybrids are common. In some regions, these hybrids would be more numerous than the type species. Observing the Dactylorhiza is the demonstration that once again, certain specialists tend to segment and name  which are sometimes only varieties. Evolution is certainly underway, but this will not happen on the scale of current humanity. Patience! 

I will therefore present only a few species, those whose identification remains certain.

Dactylorhiza fuchsii is a plant that likes many environments, dry or humid but rather on calcareous soil. The flowers are quite colorful but we will not trust the very variable designs, rather the cut of the labellum which forms a pronounced point.
