tub02 | Delimitation of this order against the Thero-Airetalia (Koelerio-Corynephoretea) needs further study since alliances such as the Molinerion laevis Br.-Bl. et al. 1952 and the Sedion pedicellato-andegavensis Rivas-Mart. et al. 1986 show a high level of floristic similarity with the Thero-Airetalia.
