The chromosome numbers of Epilobium palustre (2n=36), Geranium pyrenaicum (2n=26), Sium sisarum (2n=20), Veronica beccabunga (2n=18) were reported for the first time for the flora of Iran. Ferula persica (2n=22) and Tragopogon jesdianus (2n=12) are reported for the first time. The report for Bromus scoparius (2n=28) is the second count for the species in Iran.
