Festuca of North America
Byull. Mosk. O-va Ispyt. Prir. Otd. Biol. 87: 111. 1982. Type: U.S.A. California: Santa Clara Co., 6 May 1921, A. H. Wolley-Dod 207. Holotype: K.
Alexeev (1982) suggested that this is a distinct taxon differing from F. californica Vasey in not having tufts of collar hairs and in having a longer ligule. In an extensive study of collections of F. californica, only one specimen with a longer ligule was found but in all other respects it resembled F. californica. The character, tufts of collar hairs, was found to be very variable.
