habitat, have been less disturbed by the inroads of civiliza- 

 tion than any other group and will continue longer for 

 the same reason. 



The Fern Allies of Ohio are a very much neglected 

 group of plants. Familiarity has bred contempt for two 

 or three of the most common ones, while a lack of attrac- 

 tive features has probably caused others to be passed by 

 for their more showy fellows. More investigation is 

 needed in order to complete a thoroughly reliable list of 

 the Fern Allies of Ohio. In all seventeen species are in- 

 cluded in Dr. Kellerman's State Catalogue, but of this 

 number, four are not referred to any locality, leaving one 

 in doubt as to their occurrence. It is highly probable that 

 most of them occur in greater abundance than is indicated 

 in the following list, and also that a careful search will 

 reveal still other species not now recorded as occurring 

 in this State. 



The student of Ohio ferns who has never visited the 

 sandstone rocks at Dundee, Tuscarawas County, has a 

 rich treat in store for him, and should spend at least two 

 days in this vicinity, for it abounds in things full of inter- 

 est to the general botanist as well as to the fern student. 



In the summer of 1905, in the course of a two hours' ex- 

 ploration of a wet, hilly woodland of 12 acres in Wayne 

 County, I found 14 species of ferns — the most I had ever 

 seen up to this time in a single afternoon's walk — in- 

 cluding the very rare (for Ohio at least) Nephr odium 

 cristatum clintonianum. In the early part of September, 

 1905, in the " Garden of the Gods," three miles north of 

 Massillon, sixteen of the commoner species were found 

 within a radius of half a mile. Induced by and in com- 

 pany with some friends who are fond of outdoor life, a 

 visit was paid to Sigrist's Rocks at Dundee on August 

 28th, 1906. My skepticism soon gave way to the greatest 

 delight, for growing within half a mile of each other, were 

 found no less than twenty species of ferns, proper, vary- 

 ing in number from the common polypody which covers 

 the sandstone rocks by the thousand, to a single fruiting
