Data on the chromosome counts of ten taxa of the genus Galium are reported from northeastern Iran. Two basic chromosome numbers, i.e. x = 10 and x = 11, as well as three ploidy levels, i.e. 2 x , 4 x and 6 x are reported. Both diploid and polyploidy levels are observed. Aneuploidy was only observed in G. aparine. The chromosome numbers of the following taxa are counted for the first time: G. diploprion , G. humifusum, G. nigricans with 2 n = 22 and G. spurium subsp. ibicinum with 2 n = 20. The new data are compared with previous karyological information, and are discussed. (© 2015 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
