Abstract
Na základě studia herbářových dokladů a literatury byly sestrojeny předběžné mapy rozšíření taxonů Hieracium bauhini a H. densiflorum v ČR. U vybraných populací obou druhů zjišťován počet chromozomů. U druhu Hieracium bauhini byly zjištěny počty 2n = 36 (1 populace), 2n = 45 (41 populací) a 2n = 54 (4 populace). U druhu H. densiflorum byly zjištěny počty 2n = 36 (8 populací) a 2n = 45 (2 populace).
Abstract (in English)
Maps of distribution of Hieracium bauhini and H. densiflorum in the Czech Republic were constructed, examination of herbarium specimens and literature data were used. In selected populations were detected chromosome numbers. H. bauhini occurs in the Czech Republic in three ploidy levels: tetraploid (2n = 36, 1 population), pentaploid (2n = 45, 41 populations), and hexaploid (2n = 54, 4 populations). H. densiflorum occurs in the Czech Republic in two ploidy levels: tetraploid (2n = 36, 8 populations) and pentaploid (2n = 45, 2 populations).
