Genome size of grass Festuca mountain species from the southwestern European Pyrenees: variation, evolution, and new assessments

Festuca is one of the most ecologically and economically important genera of temperate grasses. Species of its type subgenus, Festuca, are common components of cool-seasonal pastures and are especially frequent in mountainous areas, where there are often several morphologically similar species that...
