Description	Background and aims: Intraspecific genome size variability of Festuca pallens Host (Poaceae, Poaeae) occurring on relict rocky steppes in Central Europe was studied on two ploidy levels and three geographical scales: (i) local scale of 24 populations; 3 to 6 plants per population; (ii) landscape scale of three 9 to 13 km long transects in river canyons or hill systems; 15 to 34 samples per transect; (iii) global scale of 160 samples covering the whole distribution area. Methods: DAPI flow cytometry; homogenously cultivated samples (more than 1 year); measured randomly during one week with two internal standards Lycopersicon esculentum, Pisum sativum. The differences in DNA content were confirmed by the double-peaks of simultaneously measured samples. Key results: On a global scale, the DNA content ranged 1.170 fold in diploids, and 1.164 fold in tetraploids. In 16 of 24 populations significant variability was proved (P<0.001). On a landscape scale, a maximum difference of 1.
