men was found in an open woods near Middlefield in the 

 same county. 



Botrychium Lunaria L. Moonwort. This is re- 

 ported from Lake County. 



Botrychium matricari ^folium A. Br. Matricary 

 Grape-fern. Know only by specimens from Cuyahoga 

 County. It is unquestionably one of the rarest ferns of 

 the State. The reader unacquainted with the local 

 geography of Ohio, would do well to note that this and 

 the two preceding species are found in four counties only 

 (Lake, Portage, Cuyahoga, and Geauga), either border- 

 ing on or closely adjacent to Lake Erie, in the extreme 

 northeastern corner of the State. 



Botrychium Virginianum L. Rattlesnake Fern. 

 Common in rich woods everywhere. It could probably 

 be found in every county in the State if one were to 

 search for it. It varies greatly in size from diminutive 

 plants to those over two feet high in more favored local- 

 ities. 



OSMUNDACE^E. 



Osmunda regalis L. Royal Fern. Abundant; found 

 with the following species: 



Osmunda cinnamomea L. Cinnamon Fern. Of great 

 size and abundance in the small marshes and bogs which 

 abound in the northern part of the State, but rather rare 

 south of the fortieth parallel, owing to the lack of proper 

 ecological conditions. The same might be said of O. 

 Claytoniana. 



Osmunda Claytoniana L. Clayton's Fern. My ex- 

 perience has been that this plant fruits most abundantly in 

 open fields and roadside thickets, rather than in rich 

 woods where the larger plants are usually sterile. In such 

 places it is a beautiful plant, and often transplated to yards 

 in the north where it thrives, and becomes fertile. I have 

 seen open fields near Thompson, Geauga County, contain- 

 ing hundreds of plants of this fern.
