Abstract:

Based on results of recent phylogenetic studies, two new sections of Festuca L. (F. sect. Lojaconoa, F. sect. Dimorphae) are described from the Euromediterranean region. Festuca sect. Lojaconoa is typified by Festuca coerulescens and also includes F. patula. Festuca sect. Dimorphae is typified by F. dimorpha and also includes F. laxa and F. pseudolaxa. Differentiation of these groups from other tax, traditionally considered related [i.e., Festuca sect. Subbulbosae Nyman ex Hack. and F. sect. Amphigenes (Janka) Tzvel.], is discussed. Festuca sect. Subbulbosae is lectotypified. The correct names of the species hitherto known as Festuca carpatica F. Dietr. and F. triflora Desf. are F. pseudolaxa Schur and F. patula Desf., respectively.
