After a nomenclatural revision of the available names for the order of rocky grasslands of the Balkan Peninsula within the class Festuco-Brometea, based on Article 52 ICPN we propose the conservation of the name Koelerietalia splendentis against the name Halacsyetalia sendtneri. In syntaxonomic concepts not combining the limestone and serpentine rocky grasslands of the Balkans in a single order, the latter name would still be available as it is based on a different nomenclatural type.
