title: ON THE HERBARIUM COLLECTION OF POPULATIONS OF FESTUCA L. SPECIES (POACEAE) (LWKS)
abstract: As a result of monographic studies of taxonomy of the genus Festuca in the flora of Central Europe, a specialized herbarium collection of the genus was established on the base of LWKS. The key peculiarity of the collection is the populational approach to the material. As of today, about 600 population sample groups with 20-30 specimens in each are stored, which total approximately 15 000 plants. The collection represents diversity patterns in populations (mostly narrow-leaved fescue species) in
