Jennings: Notes on Pteridophytes 47 



35. Matteuccia Struthiopteris (L.) Todaro. 



In moist, rich soil: Ft. William; Kakabeka Falls; 

 Nepigon. Not noted at any stations east of Nepigon. 



The absence in the collections of a number of ferns 

 which had been expected to occur in the region covered 

 is rather noticeable. No specimens of Adiantum or true 

 Asplenium were seen, nor did Polystichum Lonchitis 



appear 



them
