72 PHEGOPTERIS 



LONG BEECH FERN: 



Phegopteris polypodioides. 

 {P. Phegopteris.) 



Fronds triangular, longer than broad, often 18 

 inches high, pinnate; pinnae long, narrow, acute, 

 cut nearly to the midrib into oblong, blunt seg- 

 ments, the upper forming a lobed border along the 

 rachis, the lower separate, standing forward and 

 downward; intergrading forms between this and 

 the broad beech fern frequent. 



Fruit dots small, round, without indusia, borne 

 near the margins of the segments. 



Found in damp, rocky woods and along the bor- 

 ders of woodland brooks, from Newfoundland to 

 Alaska, south to Virginia, Iowa, Wisconsin and 

 Washington.
