[345] THE MOSSES OF ALASKA 305 



and James (Proced. Amer. Acad., xiv, p. 139, and Manual, p. 405). 

 These authors compare their plant to Hypnum Schrcbcri, to which 

 this var. gracilius bears no resemblance, and attribute to it obtuse 

 leaves, whereas they are apiculate on the moss of which we are speak- 

 ing. Besides, it would be very surprising if such experienced bry- 

 ologists as Lesquereux and James had not noticed the evident relations 

 which would have existed between their species and Hylocomium 

 splcndens, if the identification proposed by Mr. Kindberg was exact. 

 Until the contrary is proved, we think that H. alaskanum Lesq. & 

 Jam. is a different species, much more resembling H. schrebcri than 

 Hylocomium splcndens. 



Hylocomium umbratum Br. eur., fasc. 49-52, p. 6, pi. 2. 



From Yakutat Bay (Trelease, 1965 in part) ; Disenchantment Bay 

 (Trelease, 2048). New to Alaska. 



Hylocomium squarrosum Br. eur., fasc. 49-52, p. 9, pi. 6. 



Yakutat Bay (Trelease, 1821 in part, 1959, 2328) ; Point Gustavus 

 (Saunders, 2000) ; Cape Fox (Trelease, 1965) ; Sturgeon River Bay, 

 Kodiak (Trelease, 1932) ; Unalaska (U. S. S. Albatross Exped., 19) ; 

 St. Paul Island (Trelease, 1862, 1974) ; Hall Island (Trelease, 1883). 



Numbers 1959, 1965 and 2000 are forms coming more or less near 

 H. calvescens (Wils.) Jaeg., but on the plant from Finland the 

 acumen is broader and shorter, which constitutes the chief character of 

 this form, which, otherwise, it is impossible for us to specifically sepa- 

 rate from H. squarrosum.
