Abstract

Realignment of Festuca subgenus Schedonorus with the genus Lolium (Poaceae).

Abstract

Evidence from the literature of the close relationship between Festuca subgenus Schedonorus and Lolium, and its relatively distant relationship with Festuca subgenus Festuca is discussed. New combinations of Lolium subgenus Schedonorus, L. arundinaceum, L. giganteum, L. mazzettianum, L. pratense and L. Ă—festucaceum are proposed to reconcile classification with known phylogeny. The paniculate inflorescence and the presence of a lower glume are the principal morphological characters separating subgenus Schedonorus from Lolium. The incorporation of the subgenus into Lolium would require only slight changes to published generic descriptions.
