Schott was studied. The results showed that the spores are monolete,elliotical in polar view and semicircle in equatoral view. The germination is of the Vittara-type, and the germ filament developes 2~9 cells long. The apical cells are obvious. Prothallial plate is multicellular plate. Apical meristem still divide and develop to young prothallus. The prothallus is of the Aspidium-type. Quantity of hair is large,and each is unicellular. The antheridia and archegonia are smaller, and seem to develop at the same time. The adult prothallus are cordate-thalloid. It appears that the gametophytes of Dryopterisfragrans (L.)Schott possess some evolving characteristics of the fern. %U https://bbr.nefu.edu.cn/EN/10.7525/j.issn.1673-5102.2006.03.004
