Abstract: The spores of the Plagiogyria euphlebia was grown in a liquid medium containing modified Knop,and the whole process of spore germination and gametophyte development were recorded by optical microscope.The results showed that: The spore germination was Vittaria-type,and the gametophyte development was Adiantum-type. Mature spores are nigger brown,opaque and radiation symmetry, obtuse triangle in polar view and circular in equatorial view,trilete,peripheral wall with particles and smooth surface.The spores germinated about 34 days after sowing,forming 2-5 cells long of filaments and bring rhizoid.The prothallial plates formed around 43 d after inoculation.The young prothallium developed about 65 d after sowing which were not symmetry. While the mature prothallus was symmetrical cordate type.Papillary trichomes spread on the margin of the prothallium.These papillary trichomes consisted of single cell.Sexual organs appeared on minority prothallus around 85 d after sowing,consisting of 3 cells.The neck of mature archegonium was composed of 4 rows of cells.

Key words: Plagiogyriaceae, Plagiogyria euphlebia, gametophyte
