120 WOODWARDIA 



NARROW-LEAVED CHAIN FERN: 



Woodwdrdia areolata. 

 (W. angustifolia.) 



Sterile and fertile fronds dissimilar; sterile 

 fronds 12 to 20 inches long^ cut nearly to the mid- 

 rib into oblongs acute^ finely-toothed divisions, the 

 lower divisions often narrowed abruptly at the 

 base, the upper connected by a broad wing; fertile 

 fronds taller than the sterile, appearing later, pin- 

 nate, with long, very narrow and distant pinnae, 

 which are just wide enough for two lines of large, 

 elongated, sunken fruit dots ; indusium thick ; 

 stipes black and shining. There are many grada- 

 tions between the two classes of fronds. 



Found in wet woods, chiefly near the Atlantic 

 coast, from Maine to Florida and Texas, locally 

 inland in Arkansas and Michigan.
