THE MOSSES OF ALASKA 307 



Grimmia torquata Grev. Scot, crypt, fl., iv, p. 199. 

 From Kodiak (Trelease, 2203, 2204). 



Grimmia elatior Br. eur., fasc. 25-28, p. 17, pi. 10, forma? 



From Yukon River (W. H. Dall). New to Alaska. 



We find only some stems of this moss, with a single capsule, mixed 

 with Polytrichum yukonense Card. & Ther., and their determina- 

 tion remains rather doubtful. 



Kindberg has recorded from Alaska G. agassizii Sulliv. and Lesq. and from 

 Unalaska G. crassinervis C. Mull. 



Rhacomitrium patens Hub. Muscol. germ., p. 198. 

 From Unalaska (J. M. Macoun). 



RHACOMITRIUM SUDETICUM ALASKANUM var. nov. 



Forma minor, habitu varietati tenellum Boul. similis, sed foliis 

 subepiliferis vel apiculo hyalino omnino destitutis costaque validiore 

 distincta. 



Hidden Glacier Inlet, Yakutat Bay (Trelease, 2508 in part). 



Rhacomitrium aciculare Brid. Mant., p. 80. 



From Juneau (Coville and Kearney, 573) ; Kodiak (Trelease,

 Rhacomitrium nevii Wats. Bot. Calif., 11, p. 381.

 S. Albatross Exped., 47) ; Hot Springs (Trelease, 1769, 2346, 



2 35°)- 



Number 2322 is a forma ininor. 



Rhacomitrium tenuinerve Kindb. Rev. bryol., 1896, p. 19. 



R. fasciculare var. haplocladon Kindb. Not. on Can. bryol., 1893. 



R. microcarpumv&r. palmeri Kindb. apud Macoun, Cat. Can. pi., vi, Musci, 



p. 267. 

 R. palmeri Kindb. Rev. bryol., 1896, p. 19. 



From St. Paul Island (J. M. Macoun) ; St. Matthew Island (Tre- 

 lease, 1885, 2169); Pribilof Islands (Palmer, 1891). 



R. tenuinerve and palmeri of Kindberg surely constitute but one 

 species, which differs from R. fasciculare Brid. principally by its 

 weak, flat costa, disappearing far from the point. Kindberg is mis- 

 taken in attributing to R. palmeri a percurrent or subexcurrent costa.
