Description
Summary:Chromosome numbers are given for the following species of Taraxacum sect. Palustria from Poland: T. paucilobum Hudziok (2n = 24, 25), T. belorussicum Val. N. Tikhom. (2n = 24), T. subdolum Kirschner & Štěpánek (2n = 24), T. udum Jordan (2n = 24), T. trilobifolium Hudziok (2n = 24), T. bavaricum Soest (2n = 24), T. portentosum Kirschner & Štěpánek (2n = 32), T. vindobonense Soest (2n = 32), and T. brandenburgicum Hudziok (2n = 32). The chromosome numbers of T. belorussicum and T. portentosum are published for the first time, and for T. subdolum, T. bavaricum and T. brandenburgicum for the first time from Poland. The analyzed group of taxa is heterogenous in respect of stomatal size, and after pooling of data the tetraploids show bigger stomata than the triploids.
