270 BRITISH FERNS 



V 



ATHYRIUM FIL1X-FCEMINA, VCIV. ClARISSIMA (Jones) 



R. Moule. North Devon. 1868. 



Under glass by Captain Jones. It has been thought desirable 

 to print another frond of this variety to show the development of 

 which it is capable. Though barren it produces an infinity of 

 abortive spore cases.* 



* X.B. — It was upon this fern that the phenomenon of " apospory " was 

 first discovered by the author (vide " Life History of Ferns ").
