Chromosome counts are reported from 19 populations representing seven genera and 11 taxa of the subfamily Salicornioideae (Chenopodiaceae) from Iran. In all studied accessions a basic chromosome number of x=9 is reported. First chromosome numbers are reported for Halostachys belangeriana (2n=8x=72), Halopeplis pygmaea (2n=2x=18) and Kalidium capsicum (2n=4x=36). The species of the genus Salicornia are divided into tetraploid and diploid groups. The newly described endemic species S. persica is only tetraploid (2n=4x=36). But the diploid group (2n=2x=18) may represent three different taxa.
