Some New Records of Chromosome Numbers in Iranian Charophytes

Chara is an interesting genus from cytological view has been extensively worked out in Europe and North America, but there is a few reports on Asian Charophytes. Chromosome number were determined for 10 species of Chara from 33 populations. Chromosome counts were as follows: C. connivens, n=14, C. contraria, n= 28; C. crassicaulis, n=21; Chara gymnophylla var. gymnophylla, n=14; Chara gymnophylla var. rohlenae, n=14; C. kirghisorum, n=14; C. kohrangiana, n=21, C. socotrensioides, n=14; C. tomentosa, n=14; Chara vulgaris var. longibracteata, n=28 and Chara vulgaris var. vulgaris, n=28. Authors made cytological studies of Iranian charophytes in twelve taxa which 10 taxa are new for Iran and five taxa are new for science.
