This was one of the first ferns collected by the writer, 

 several years ago in Geauga County. Since that time he 

 has not seen it growing anywhere. It is reported from 

 five other counties than the one named, but is not plenti- 

 ful in Ohio. 



Onoclea sensibilis (L.) Sensitive Fern. Common 

 everywhere in wet woods, marshes, thickets, and borders 

 of woods. I have experienced no trouble in finding fer- 

 tile fronds. A single specimen of the so-called variety 

 obtusiloba was collected in Wayne County in 1904. 



Onoclea struthiopteris (Hoff.) This enjoys the 

 distinction of being included in the first catalogue of 

 Ohio's flora, then excluded and included in one and the 

 same bulletin. I have seen this species exposed for sale 

 in the streets of Cleveland, almost by the wagon load, 

 under the name of " southern palm fern." I have reason 

 to believe it has been offered in the market at Spring- 

 field, but of this I am not quite certain. Near Middlefield 

 there is a station for this plant, which contains over forty 

 strong, vigorous plants. The yards of Wooster contain 

 many really magnificent specimens of the ostrich fern, 

 and I believe a careful search of all available territory 

 would reveal its presence in Wayne County. 



Woodsia obtusa (Spreng.) Obtuse Woodsia. Limited 

 to the southern part of the State where it is fairly 

 abundant wherever there are out-croppings of lime- 

 stone. It is to be looked for in company with the bladder 

 ferns and the purple cliff-brake. However, it differs 

 from them in that it seems to prefer detached boulders 

 rather than the face of the cliff for its home. 



Asplenium fontanum (L.) Sometimes credited to 

 Ohio, but at the present is not authenticated by any her- 

 barium specimens. All told I have spent several weeks 

 searching for this fern at Springfield, it reputed home. 

 It is needless to say I did not find it, but then not near all 

 of the available territory was gone over, and that by one 

 pair of eyes only. For the present at least, it should be 

 excluded from the list Ohio ferns.
