| Abstract: | The fern Pyrrosia lingua was cultured artificially, and the whole development course of its gametophyte was observed and recorded. Its spores are monolete and bilateral, with their surface tuberculate; the germ filament develops 2 -4 cells; young prothalli are dissymmetrically cordiform, mature prothallus cordate; the trichomes occur in the platellite, and the development of prothallus is of the Aspidium-type; the shape of basal cells of trichomes are diverse; sexual organs mature in about 60 days. |
