From Yes Bay (Gorman, 184) ; Juneau (Brewer and Coe, 699$, 

 700); Skagway (Canby, 478); Wrangell (Trelease, 2317); White 

 Pass, 3,000 ft. (Trelease, 2313); Farragut Bay (Trelease, 2416; 

 Brewer and Coe, 617); Yakutat Bay (Trelease, 1763, 2340); Point 

 Gustavus (Coville and Kearney, 777) ; La Perouse Glacier (Trelease, 

 2498) ; Sitka (U. S. S. Albatross, 53, 55 ; Canby, 458, 463 ; Trelease, 

 2359) ; Hot Springs (Trelease, 1914) ; Kodiak (Trelease, 1853) ; 

 Douglas Island (Trelease, 1908, 2392) ; Port Wells (Trelease, 2282, 

 2288); Orca (Trelease, 1918, 1925, 2262; Setchell, 1213); New 

 Metlakatla (Coville and Kearney, 364) ; Plover Bay, Siberia (Trelease, 

 1865). 



The Yes Bay specimen was associated with Mnium glabrescens 

 Kindb. and Scapania sp. 



The Kodiak specimen (1853) * s a pahidal form, with entire, shorter, 

 erect leaves. We must point out too a sterile form, collected on Unalaska 

 Island by Mr. C. H. Townsend (U. S. S. Albatross exped., 43), which 

 is very near D, muehlenbeckii Br. eur. var. brevifolium Lindb. The 

 same form was found by Trelease on Hall Island ( 1907) . It differs from 

 the European plant chiefly in having its leaves less flexuous when dry. 



Many authors separate D. congestum Brid. from D.fttscescensTurn. 

 but as it is almost impossible to find two descriptions of D. congestum 

 which agree, we can infer that it is one of those species which every 

 author understands in his own way, that is to say a very bad species ; 

 and we deem it preferable to merely unite it with D. fuscescens.
