| Abstract: | The gametophyte development of Athyrium mackinnonii from China was observed under artificial culture in this paper. The results show that the spore of Athyrium mackinnonii is bilaterally symmetric, elliptic in polar view, fabaceous in equatorial view, the rugate is formed by the perispore. The pattern of spore germination is of Centripetal-type. The prothallial development is of Adiantum-type. The developed prothallial is cordiform. The male gametophyte is strip-shaped. It provides some information for system classification of Athyriaceae. |
