epi17 | This alliance has a transitional position between the Artemisietea and Epilobietalia angustifolii and therefore an alternative classification within the Artemisietea is also possible. (M. Chytrý, L. Mucina).

Eu-Arction Sissingh in Westhoff et al. 1946 (orig.form) (as suballiance)
– epi18 Sometimes this unit (under the name 'Eu-Arction Tx. 1937 em. Sissingh 1946') is considered at the alliance level, which is a wrong perception/interpretation since it has been described by Sissingh (in Westhoff et al. 1946: 31) explicitly as as '(Eu-) Arction Sissingh suball. nov.', hence as a suballiance. (L. Mucina).
