Ähnlich wie O. palustris, aber Blüten dunkel purpurviolett, Lippe sattelförmig, mit nach unten gebogenen Seitenabschnitten (bei O. palustris Lippe +/- flach), Mittellappen sehr kurz, höchstens so weit nach vorne ragend wie die breiten Seitenabschnitte (bei O. palustris Mittellappen die Seitenlappen überragend), Sporn horizontal oder etwas aufwärts gebogen, an der Spitze gefurcht (bei O. palustris ohne Furche).

Disclaimer
InfoFlora compiles information on protected species as accurately as possible, taking it from the respective cantonal laws. In some cases, however, it was not possible to use the plant names as listed in the original text, but an interpretation of their taxonomy or nomenclature was necessary. The exact meaning of the categories „completely protected“ and „partially protected“ differs among the cantons.
InfoFlora cannot guarantee that the information on the protection status is correct and complete. In case of doubts, we recommend to look up the texts of the respective cantonal law.
