In this paper, the chromosome numbers of 9 taxa belonging to the Veronica L. (Scrophulariaceae) from Iran are presented. The chromosome number of V. capillipes Nevski (n=14) is published for the first time. The other counts, of V. campylopoda (n=21), V. polite (2 n=14), V. persica (n==14), V. hederifolia (2n=54) , V. Anagallis - aquatic a subsp. oxycarpa (n=18), V. Anagallis - aquatic a subsp. Michauxii (2 n=36), V. Ana gall oides subsp. hureka (n=9), agree with earlier findings. At the end the cytotaxonomic results are discussed.
