96 FERNS AND THEIR ALLIES 



short-stalked and crenately toothed, from ten 

 to twenty each side of the rachis. 



This fern was discovered by Pringle on Mt. 

 Mansfield, Vermont, and so far as we can learn, 

 it is still confined to the mountains of Ver- 

 mont. 



Green Spleenwort usually is found in almost 

 inaccessible places on shaded cliffs. The fronds 

 grow in tufts and are evergreen. 



It resembles Maidenhair Spleenwort, but 

 one point alone serves for identification. In 

 this the rachis is green, passing into a brown- 

 ish stipe at the base, while in Maidenhair 

 Spleenwort the stipe and rachis are dark and 

 glossy. 



The fruit-dots are large and oblong ; they 

 mature in July. The indusium is curved or 

 straight. 



MOUNTAIN SPLEENWORT. 



Asplenium 7nontanum. 



Frond from two to five or si.x inches long, 

 broad at the base, pinnate. The lower pin- 

 nae are cleft into several cut-toothed lobes, 

 the upper gradually becoming simpler. The 

 stipe is brown at the base, flat and green 

 above. 



The fronds are somewhat leathery in texture, 

 bluish-green in color, and evergreen.
