Notes.

Dactylorhiza maculata is often hardly distinguishable from D. fuchsii . When they co-occur, they form populations that include plants with intermediate morphology, indicating possible hybridisation. We consider that D. maculata is generally a European species, with only isolated occurrences in Asia, particularly in the western part of Siberia and in Kazakhstan. Determining the exact eastern distribution limit of this species is challenging due to its similarity with D. fuchsii in this region, where their ranges overlap.
