Neues Konzept: die Art ist gegenüber SISF-2 enger gefasst, da mindestens ein Taxon davon abgetrennt wurde. Entspricht dem Konzept von O. biennis aggr. gemäss SISF-2, ausgenommen der in O. villosa aggr. enthaltenen Taxa. Die Aufteilung der Gattung in Aggregate folgt dem taxonomischen Konzept von Dietrich («American School»), während sich die Definition der Arten an den Vorschlägen von Rostański orientiert («European School»).

- 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.
