The form is probably a sport but as such it seems to deserve 

 a name as it is likely to occur elsewhere. Therefore, I propose 

 the name: 



Adiantuni pedatum L. var. laciiiiatitin Hopkins var. nov. 



Pinnules linear, lanceolate, or oblanceolate, more or less 

 branched; growing with the type; rocky wooded hillsides, 

 Wayne County, O. (Fig. 1). 



Fig. 2. Cystopteri.s fragilis cristata Hopkin.s. a, 1>, c. Apexes of frond. 



d, e, f, Pinnae. 



In the latter part of August, 1909, in company with Mr. 

 R. J. Webb, of Garrettsville, and Mr. A. X. Rood, of Phalanx, 

 I visited Woodworth's Glenn, in Portage County. 



A clear rapid flowing stream very suggestive of trout has cut 

 out a small ravine through the sub-carboniferous (?) sandstone. 

 In some places this ravine is quite narrow and the walls almost 

 perpendicular.
