Abstract: The spores of Cystopteris fragilis are monolete with spinate exine and devoid of perine. On germination a germ filament is produced which when 4-6 cells long has the terminal cell dividing obliquely twice to form an obconical apical meristematic cell. Marginal hairs are produced by young thalli. The apical cell is replaced by a multicellular meristem when the thalli become cordate. An apical cell stage is frequently omitted and spatulate, ameristic thalli develop a multicellular meristem directly. The mature prothallus is cordate with a broad midrib and bears marginal and superficial unicellular hairs. [ABSTRACT FROM AUTHOR]
