Abstract: The spore of Camptosorus sibiricus is bilateral and monoleta. with a prominent perine. The patterns of spore gemination is of Vittaria-type (Nayar & Kaur 1971). The germ filaments develop 2-7 cells long, uniseriate or multiseriate. The prothallial development is of the Aspidium-type (Nayar & Kaur 1971). The prothalli are cordate and hairy with median light midrib. The form of hair isvaried. The sex organs are rather small. The antheridial dehiscence is by pore-like opening developed in the cap cell. The neck of archegonia are slander. As mentioned above, the characteristics of Camptosorus sibiricus on the development of the gametophytes are common in a advanced fern type. It is similar with thegametophyte of Phyllitis japonica in the main characters. It seems that they would be at closed phylogeny level in the family Aspleniaceae.
