A bstract1 The chromosome numbers of 10 species of the genus Viola in the Netherlands were determined. 2 Viola riviniana has various chromosome numbers: 2n = 35, 40, 45, 46, 47 (most often 2n = 40). 3 It was not possible to find a correlation between the external morphology and the various chromosome numbers in V. riviniana . 4 Despite the variability of V. riviniana it proved impossible to divide the Dutch material into subspecies. 5 Some differential characters of V. riviniana and V. reichenbachiana are described. 6 V. canina is not variable in cytological respect in the Netherlands. 7 V. calaminaria is not related to V. lutea but to the V. tricolor complex.
