Abstract: The gametophyte development of Diplazium subsinuatum (Wall. ex Hook. et Grev.) Tagawa from China was observed under artificial culture in this paper. The results show that the spore of Diplazium subsinuatum is bilaterally symmetric, elliptic in polar view, circinal-reniform in equatorial view, the echinate or baculate is formed by the perispore. The pattern of the spore germination is of Vittaria-type. The prothallial development is of Adiantum-type. The developed prothallial is cordiform. This study provides some information for system classification of pteridophytes.

Key words: Diplazium subsinuatum (Wall. ex Hook. et Grev.) Tagawa, gametophytes, development
