118 WOODWARDIA 



COMMON or VIRGINIAN CHAIN FERN: 



Woodtvdrdia virginica. 



Fronds 2 to 4 feet high^ with stipes nearly as 

 long as the blades^ quite similar in appearance to 

 the sterile fronds of the cinnamon fern^ pinnate; 

 pinnae lance-shaped;, cut nearly to the midrib into 

 blunt, slightly-curving segments. 



Fruit dots elongated, borne in two series: one 

 series borne parallel to the midribs of the pinnae, 

 and the other parallel to the midribs of the seg- 

 ments. 



Found in swamps from Nova Scotia to Florida, 

 Louisiana, Michigan and Ontario.
