Proposal (35) to conserve the name Festucion valesiacae

For ninety years, the alliance name Festucion valesiacae has been widely and almost exclusively used to designate the alliance of steppic, xeric grasslands on deep soils from Central Europe to western Ukraine. However, there is an earlier, hardly used heterotypic synonym, the Festucion sulcatae, that would be the correct name according to the rules [recte: Festucion rupicolae nom. corr.]. In order to preserve a well-established name, we propose to conserve the name Festucion valesiacae against the name Festucion sulcatae. In addition, we typify the name Festucion rupicolae Soó 1930 nom. corr. with the association Festuco rupicolae-Stipetum pennatae Soó 1930 nom. corr., for which we also select a neotype. This proposal is supported by the fact that the alliance Festucion valesiacae is the conserved type of the order Festucetalia valesiacae.
