Chromosome studies on some species of Angiosperms from Iran

Original observation on meiotic or mitotic chromosome numbers are reported for ۱۷ taxa in nine families of Angiosperms plant from Iran  including: Ammi majus (n=۱۱), Anthemis pseudocotula (n=۹), Centaurea kotschyi var. persica (n=۲۷, ۲n=۵۴), Jurinea macrocephala (n=۱۷), Scorzonera cana (n=۷), Scorzonera raddeana (n=۶), Physorrhynchus chamaerapistrum (n=۱۶), Onosma rostellatum (n=۱۲), Silene conoidea (n=۱۰), Umbilicus tropaeolifolius (n=۱۸), Polygala hohenackeriana (n=۷), Batrachium rionoo (n=۸), Hyoscyamus leucanthera (n=۱۷), Hyoscyamus niger (n=۱۷), H. pusillus (n=۳۴), H. reticulatus (n=۱۷), H. senecionis var. bipinnotisectus (n=۳۴). Chromosome count for six species: H. senecionis var. bipinnatisectus, Onosma rostellatum, H. leucanthera, Polygala hohenackeriana, Scorzonera raddeana, and Umbilicus tropaeolifolius are reported here for the first time and four count including: Ammi majus, Centaurea kotschyi var. persica, Scorzonera cana, and Batrachium rionii is new for the flora of Iran.
