PREFACE. 

 ^ 



The following list has been prepared by students of the Shef- 

 field Scientific School as a simple contribution to the botanical 

 literature of the region. Disregarding the numerous changes 

 which have been made since it- publication, it has been our 

 intention to follow in the higher groups, as far as possible, the 

 arrangement and nomenclature of Gray's Manual : and to this 

 reference must be had for the explanation of typography, abbre- 

 viations, etc. In a very few cases of unusual interest we have 

 exceeded the thirty-mile boundary, but in no case without sufficient 

 cause. 



It is abundant proof of the scientific accuracy of the list, that 

 Professor Eaton has examined and pronounced upon all doubtful 

 cases ; and we are under special obligations to him, not only for 

 constant encouragement and advice, but also for the preparation 

 of the Introduction and for compiling the entire list of Mosses 

 and Liverworts. 



It should be kept clearly in mind, that whenever Long Island is 



> mentioned, only that portion is referred to which falls within our 



limits ; and farther, that every Long Island plant, not otherwise 



credited, has been identified by Mr. E. S. Miller, of Wading 



River, who has generously supplied us with a full list of the flow- 



^ ering plants in his district. 



On our northern borders we have received very substantial aid 

 from H. J. Bassett, Esq., of the Bronson Library, Waterbury ; from 

 Miss Charlotte A. Willard who has carefully studied the plants of 

 Farmington ; from Mr. \Y. H. Patton of the Peabody Museum, 

 who lias collected largely in the neighborhood of Waterbury and 

 Xew Haven ; and from the veteran botanist, Charles Wright, 

 Esq., of Wethersfield, who has informed us of several rare species. 

 Mr. P. M. Augur, of Middlefield, our state Pomologist, has also 

 contributed much general intelligence.
