38 MB, W. MITTEN — BBYOLOGIA OF THE STJBTEY 



H. SPLENDENS, Dill. 



Hab. Saskatchewan, Bourgeau ; Vancouver Island, Lyall and Wood; 

 British Columbia, Lyall. 



Hypnum spectabile, Wils. MS., from Eussian America, is pro- 

 bably H. Butheniewn, Weinmann, Syll. Muse. Frond. ; and his 

 comparison of his specimens with Hedwig's figure of LesJcea 

 filiculiformis, Sp. Muse. t. 50, is most just and almost conclusive, 

 for it gives a good idea of the size and appearance of the species 

 even better than it does of the Hypopterygium for which it was 

 intended. 



Climactum, W. et M. 



C. dendroides, Linn. 



Hab. Pend Oreille River, British Columbia, Lyall. 



JSTeckeba, Hedw. 



N. Menziesii, Hook, et Wils. 



Hab. Fort Colville, British Columbia, Lyall. 



An authentic specimen in Sir "W. Hooker's herbarium proves 

 the Mniwm heteropterum mentioned by Dr. Sibthorp in the ' Flora 

 G-raeca' to be this moss, — at least so far as can be ascertained 

 without fructification, in which in this tribe there is frequently a 

 greater difference than in any other part of the plant. 



N. Douglasii, Hook. 



Hab. Vancouver Island, Wood; British Columbia, Lyall. 



Homalia, Brid. 



H. obtusata, Mitten, Musci Ind. 



Hab. British Columbia, Lyall. 



A few imperfect specimens, apparently identical with the 

 Indian species, which differs from IT. trichomanoides, Schreb., in 

 its more obovate leaves more rounded at their apices, the nerve 

 sometimes imperceptible, and the cells in the apex shorter. 



Thamnium, Schimp. 



T. neckeroides, (Hypnum) Hook. Muse. Exot. t. 58. 



Hab. Vancouver Island, Wood. 



One species only is enumerated by Sullivant in the United 

 States, T. AllegJianiense, 0. Miiller ; but there are the specimens of 

 T. neckeroides collected by Drummond near St. Louis, no. 119 ; 

 and T. alopecurwn, (Jlypnwm) Linn., was sent from Boston by 

 Green.
