THE MOSSES OF ALASKA 



BY J. CARDOT AND I. THERIOT 

 INTRODUCTION 



THE following catalogue of the mosses of Alaska and some 

 adjacent islands is based primarily upon the collection made by 

 the Harriman Expedition in 1899. For completeness, how- 

 ever, species previously reported from the region are also 

 included. 



The whole number here enumerated is 280, of which 124 are 

 new to Alaska and 46 are new to science. The 29 new species 

 and 17 new varieties, except for three species of Bryiim^ are 

 here first described. 



The mosses brought back by the Harriman Expedition were 

 collected by Wm. H. Brewer, W. R. Coe, L. J. Cole, F. V. 

 Coville, T. H. Kearney, De Alton Saunders and Wm. Trelease. 



Previous collections were made by W. H. Dall, 1867 ; Krause 

 brothers, 1882 ; W. G. Wright, 1891 ; Jas. M. Macoun, 1891- 

 92 ; B. W. Evermann, 1892 ; C. H. Townsend, 1893-95 (Exp. 

 of U. S. S. Albatross} ; W. M. Canby, 1897 ; W. H. Evans, 

 1897; W. A. Setchell, 1899; F. C. Schrader, 1899.
