THE FERN BULLETIN 



pendence near Cherry Valley, appear however to have 

 been above the ice and show distinct wave marks, as 

 also do most of the hills along the valley of the Susque- 

 hanna, yet the hills to the south, of a higher elevation, 

 are covered with glacial drift, some of which must 

 have come from far to the north, as indicated by the 

 kinds of rock composing it. 



During the past three years I have covered the terri- 

 tory extending from Sidney, Delaware County, to Ot- 

 sego Lake fairly well. While the fern flora is perhaps 

 not particularly rich as a whole, yet in certain sections 

 it is rather varied, as the following will illustrate. For 

 lack of space the commoner species are passed over, and 

 only those which are worthy of note are mentioned. 



Camptosorus rhizophyllus, found in numerous rocky 

 ravines throughout the section. 



Asplenium ebeneum, Rock Hill and Catamount Mt, 

 Oneonta, and at Franklin, Delaware County. 



Nephrodium Spinulosum dilatatum, common on 

 every heavily wooded hillside and on sides of wooded 

 ravines. 



Nephrodium Boottii, found in nearly ever} 7 wooded 

 swamp about Oneonta, and southward in the Ouleout 

 Valley. 



Nephrodium Goldicanum, two or three stations about 

 North Franklin in the Ouleout Valley. 



Nephrodium cristatum x Marginalc, swamp near 

 "Chinese Wall," Oneonta. 



Cystoptcris bulbifera. found in several ravines on the 

 north side of the Susquehanna Valley, also throughout 

 the Ouleout Valley. 



Woodsia Ilvensis, a small station of exceedingly vig- 

 orous plants on the summit of a cliff on Rock Hill, 

 Oneonta, elevation 1500 ft.; on the top of a dry shale
