SCOPE AND CHARACTER OF PRESENT PUBLICATION. 



This catalogue is the first to include all the groups of plants repre- 

 sented in Ohio. Our knowledge of the flowering plants and of the 

 higher cryptogams, or flowerless plants, is based on the work of many 

 botanists and hosts of collectors. A large portion of the collected mater- 

 ial has passed through our hands and we have visited many portions of 

 the state. But few of our botanists have studied the Mosses, Liverworts, 

 Lichens, Fungi and Algse and collectors have almost invariably neglected 

 them. The list in the lowest groups (Thallophytes) must be considered 

 very fragmentary and a mere beginning. 



The state catalogue also differs from its predecessors in giving 

 stations (with credit to first collectors) for all except the commoner 

 plants. It has been the aim to admit no plant of doubtful occurrence, 

 though in some of the groups, especially in the Algse, no censorship was 

 possible. 



A tabulation for popular use is here inserted, presenting a compre- 

 hensive view of the several groups and their relation to each other.
