The karyotypes (chromosome sets) of Trollius austrosibiricus, T. kytmanovii, and T. riederianus have been investigated for the first time. The karyotype formula has been obtained as 2n = 2x =16 = 2m + 2m/sm + 12sm for Trollius austrosibiricus and T. riederianus, and 2n = 2x =16 = 4m + 12sm for T. kytmanovii. A comparative analysis of the chromosome sets was conducted for these three species and the previously studied Trollius altaicus, T. asiaticus, T. ledebourii, and T. lilacinus (Hegemone lilacina) for several karyological parameters. The average absolute nuclear DNA content (2?-value) was originally determined for Trollius austrosibiricus, T. kytmanovii, T. ledebourii, and T. riederianus by flow cytometry.
