To keep the Excursion Flora of Austria and other Central European floras up to date, systematics, taxonomy and nomenclatural correctness within the Festuca-Lolium group (core of the subtribe Loliinae) were critically evaluated in light of recent molecular phylogenetic investigations. This resulted in a taxonomic concept based on two monophyletic main genera, Lolium and Festuca, both being associated with various basal groups, which can be separated at generic rank as required, allowing phylogenetic relationships to be reflected as reliable as possible. Within the area covered by the upcoming fourth edition of the Excursion Flora of Austria and the Eastern Alps, only one such basal group (Drymochloa) is of relevance. New names and combinations required by this updated taxonomy are provided.
