MOSSES OF SEVERAL OHIO COUNTIES. 



Edo Claassen. 



In the course of the last 20 years excursions were undertaken 

 now and then, mostly in Northern Ohio, to prepare a list of 

 the Moss Flora of that part of the State. The names of the 

 counties where the species were collected are abbreviated: 

 C stands for Cuyahoga, E for Erie, G for Geauga, L for Lake, 

 Li for Licking, M for Medina, O for Ottawa, P for Portage, 

 Pe for Perry and S for Summit. 



More than 1000 boxes and packages, containing an almost 

 innumerable number of specimens, represent the result. 

 They are incorporated in the collector's herbarium. Their 

 description is found in Lesquereux and James' Manual and a 

 key, helping in the determination, was published by Barnes 

 and Heald in 1896. Several of these mosses were never found 

 fruiting, as for instance, Eurynchium Boscii and Myurella 

 Carey ana, others such as Climacium americanum, Br yum roseum 

 and the Sphagnum once only. Quite a number of sterile ones, 

 however, are yet on hand, waiting to be identified, which may 

 be possible only by comparing them with the Exisccatce. 



It is the ardent wish of the writer that this list may induce 

 students of Botany to make themselves acquainted with the 

 highly interesting mosses. They can be assured that without 

 fail great pleasure will be their reward.
