CRYPTOGAMS.

 future collecting it is purposed to give more attention to 

 this part of the flora. 



ACKNOWLEDGEMENTS. 



I have pleasure in acknowledging the generous as-

 literature and data upon various topics. The services 

 rendered by Prof. B. C. Buffum in the field I have pre- 

 viously mentioned ; his continued interest and occasional 

 assistance is greatly appreciated. To Mrs. Celia A. 

 Nelson much credit is due for her painstaking care in the 

 preparation of specimans and her devotion to the work 

 during the expeditions of 1895. The task of putting this 

 manuscript in shape for the printer is work for which I am 

 also largely indebted to her. 



For assistance in the determination of certain groups

 Dr. B. L. Robinson, to whom a considerable number

 careful reports upon these I am indebted to him and Mr. 

 M. L. Fernald. Certain orders and genera were sub-
