Using flow cytometry, ploidy levels for 205 living samples of various European species of Festuca L. subg. Festuca were determined. We used successfully flow cytometry also for ploidy level estimation of other 28 additional, "-2-year-old herbarium specimens. About 23 taxa and two spontaneous hybrids originating from natural populations from Austria, the Czech Republic, France, Hungary, Germany, Italy, Poland, Romania and Slovakia were studied. The following ploidy levels were documented: F. alpestris 2n = 2x; F. amethystina 2n = 4x; F. billyi 2n = 6x; F. brevipila 2n = 6x; F. carnuntina 2n = 6x; F. cinerea 2n = 4x; F. degenii 2n = 4x; F. duernsteinensis 2n = 4x; F. duvalii 2n = 4x; F. gracilior 2n = 2x; F. lemami 2n = 6x; F. ovina subsp. guestfalica 2n = 4x; cf. F. ovina x F. pallens 2n = 2x; F. pallens 2n = 2x, 3x, 4x; F. psammophila 2n = 2x; F. pseudodalmatica 2n = 4x; F. pseudovina 2n = 2x; F. rupicola 2n = 6x; F. stricta 2n = 6x; F. vagmata subsp. dominii 2n = 2x; F. vaginata subsp. vaginata 2n = 2x; F. vaginata x F. valesiaca 2n = 2x; F. valesiaca 2n = 2x; F. versicolor subsp. versicolor 2n = 2x; F. wagneri 2n = 4x.
