THE FERN BULLETIN 



it might be caused by a late frost, but in following 

 years the plants produced the same forms. I sent 

 fronds to W. N. Clute and he considered it a form 

 worthy of a name and called it forma angnsta. Since 

 first discovering it I have found plants scattered to a 

 considerable extent through the swamp. It grows 

 among plants of the normal type, there being more of 

 the normal form than of forma angusta in any given 

 area. I have this season found it in an open dry ledgy 

 pasture several miles from the first station. The tips 

 of the fronds in the open sunlight present a rusty 

 brown shade. I have found plants that the lower por- 

 tion of the fronds were normal and the tips contracted 

 into the angusta form. I have a supply of material and 

 any member wishing a frond may have the same by 

 sending six cents to pay postage.
