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.
