94 ASPIDIUM 



MASSACHUSETTS FERN: 



Aspidium simulatum. 

 {N epJir odium ; Dryopteris simulata.) 



This fern is similar in habit to the marsh fern 

 and the New York fern, but may be distinguished 

 from them by the following characteristics: the 

 lower pinnae are somewhat contracted, but are 

 never so small as those of the New York fern; the 

 simple (not forking) veins distinguish it from the 

 marsh fern. 



Found in wet woods from Maine to Pennsylvania 

 and Maryland.
