The purpose in this research to investigate two species Pteris by anatomy method and evaluation of similarities and differences between them in the forests of northern Iran. Therefore, the populations of two species of the Pteris cretica and Pteris dentate were collected from forests of Mazandaran, Guilan and Golestan. The results of the findings show that these two species of ferns , based on the anatomy of the main components I, II and IV are different from each other , but based on other main components aren’t significantly different from each other. Also, the dentate species populations based on principal component except the sixth, no significant differences were observed, and that could indicate the presence of more than one sub- species of the dentate in northern Iran.The results show that two species of ferns, in terms of anatomy based on principal component first, second and fourth different together, but the other main components do not differ significantly. Also among the populations of Dntata based on principal component except the sixth, there was a significant difference that could indicate the presence of more than one subspecies of Dntata northern Iran.
