Validation of syntaxa names of the class Quercetea mongolicae – temperate mainland broadleaved and mixed forests of the Far East

We validate the name Quercetea mongolicae and 56 subordinated syntaxa of broadleaved and mixed forests from the Far East which were published invalidly. We suggest a new syntaxonomical decision to consider the order Lespedezo bicoloris- Quercetalia mongolicae in the class Quercetea mongolicae instead of Querco mongolicae– Betuletea davuricae Ermakov 1997.
