List of Festuca species

The following species in the grass genus Festuca, the fescues, are accepted by Plants of the World Online as of 2024. This genus together with the ryegrass genus Lolium form the Festuca–Lolium complex known for its frequent hybridization, and which is further complicated by the presence of a fine-leaved fescue clade within Festuca that appears to be sister to a clade consisting of Lolium and broad-leaved Festuca species.
