SUMMARY The relationships of six diploid Festuca species were studied: Section Montanae: F. donax, drymeja, altissima Scariosae: F. scariosa Bovinae: F. pratensis Ovinae: F. polesica. The criteria used were ability to hybridize, and fertility and meiotic chromosome pairing in the F 1 hybrids. The closest affinity discovered was amongst the species within Section Montanae, there was also a strong affinity between these and F. scariosa , and a weak link with F. pratensis and F. polesica. The results are briefly discussed from the standpoint of species‐relationships in Festuca and Lolium.
