577 Dactylorhiza incarnata (L.) Soó subsp. cruenta (O. F. Mull.) P. D. Sell

Syn.: Orchis cruenta O. F. Mull.

This calciphilous, Eurasiatic taxon has a disjunct distribution in Europe (N. Europe, Ireland and the Alps) and protrudes far eastwards through Russia and Siberia, where the occurrence of this critical (and hybridizing) taxon is insufficiently known. Thus, the map is, for this part of the range, preliminary.
