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. \o^ 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 yukoiieitse Card. & Ther., and their determina- 

 tion remains rather doubtful. 



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

 Unalaska G. crasshieri'fs C. Miill. 



Rhacomitrium patens Hub. Muscol. germ., p. 19S. 

 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, 250S in part). 



Rhacomitrium aciculare Brid. Mant., p. So. 



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

 1849). 

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



From Juneau (Trelease, 2174) ; Atka Island (J. M. Macoun). 

 Rhacomitrium fasciculare Brid. Mant., p. So. 



From Portage Bay (U. S. S. Albatross Exped.) ; Yakutat Bay 

 (Trelease, 17S5, 2322); Cape Fox (Trelease, 2377); Muir Glacier 

 (Trelease, 17S1, 2455) ; Kodiak (Trelease, 1786, 2193) ; Sitka (U. S. 

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



2350)-

Rhacomitrium tenuinerve Kindb. Rev. bryol., 1S96, p. 19. 



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



R. microcarptim var. palmeri Kindb. apud Macoun, Cat. Can. pi., vi, Musci, 



p. 267. 

 R. paiineri Kiy^ii'Q. Rev. bryol., 1896, p. 19. 



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

 lease, 18S5, 2169); Pribilof Islands (Palmer, 1891). 



R. tc7iuiiierve 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.
