covered with long and soft hairs, and are chaffy 

 on the under side ; the stipe and rachis also are 

 very chaffy. 



The frond is oblong-lanceolate in form, taper- 

 ing both ways from the middle, the lower pinnae 

 being gradually reduced in size. 



This fern was first discovered on Mt. Mans- 

 field, Vermont, by Pursh in 1807. It is consid- 

 ered by some to be a distinct species. 



It may be termed rare, as it is seldom if ever 

 found below 2000 feet altitude, growing in 

 deep, moist woods in northern New England. 

 The fronds are from one to two and one half

The fruit-dots are round and near the mid- 

 vein ; they mature in August. The indusium is 

 circular and entire, fixed by the depressed centre.
