Validation of chasmophytic syntaxa of colline and montane zones in Tajikistan (Middle Asia)

Abstract

Eight syntaxa are validated with the previous names regarded as invalidly published according to the International Code of Phytosociological Nomenclature. The validation concerns syntaxa of rock plant communities of the Campanuletalia incanescentis order reported from the Pamir Alai mountains in Tajikistan. The majority of validated syntaxa represents association level, one is an alliance. All validations are conducted due to the invalidity of tables with typus relevés according to art. 1 of the Code: they were not distributed as printed matter. The validated syntaxa are as follows: Caricion koshewnikowii, Scutellarietum hissaricae, Scutellarietum schugnanicae, Scutellarietum zaprjagaevii, Scutellarietum baldshuanicae, Tylospermetum lignosae, Nanorrhinetum ramosissimi, Campanuletum albertii.
