20 MR. W. MITTEN — BRYOLOGIA OF THE STJRYEY 



specimens there occurred a few of what appears to be a different 

 species : — 



G. platyphylla. Foliis incurvis imbricatis late ovatis apice obtusis 

 apiculove brevi diaphano terminates marginibus revolutis nervo in 

 apice evanido, foliis perichaetialibus late ovali-oblongis apice obtuse 

 angulatis, cellulis elongatis teneris fere ad apicem usque areolaris, 

 tbeca immersa ; caetera G. apocarpce sirailis. 



Hab. Davis's Straits, Taylor. 



In habit, colour, and general appearance agreeing with G. apo- 

 carpa, var. stricta ; but its leaves are more than twice as wide, 

 and both in the wet and dry state imbricated ; in their substance 

 and areolation they agree exactly with those of G. apocarpa, and 

 the capsule and peristome appear precisely the same ; the peri- 

 chaetial leaves are very laxly areolate for two-thirds of their length. 

 The specimens, from their very wide leaves, are immediately dis- 

 tinguishable from all known varieties of G. apocarpa. 



(Eugrimmia, C. Muller.) 



G. leucophjea, Grev. 



Hab. Fort Colville, Lyall. 



Bather more slender than European specimens. 



G. alpestris, Schleich. 



Hab. Fort Colville and Pend Oreille River, Lyall. 

 All the specimens very dark green, but not otherwise differing 

 from European ones. 



G. pulvinata (Linn.). 

 Hab. Fort Colville, Lyall. 



G. TRICHOPHYLLA, GreV. 



Hab. Vancouver Island, Lyall. 



G. patens, (Bryum) Dicks. 



Hab. Between Fort Colville and the Rocky Mountains, Lyall. 



(Dryptodon, Brid.) 

 G. actcularis, Linn. 

 Hab. British Columbia, Lyall and Douglas. 



The capsule in some specimens elongated ; but in other parti- 

 culars like the European moss. 



(RJiacomitrium, Brid.) 



G. heterosticha, (Trichostomum) Hediv. 

 Hab. Fort Colville and Pend Oreille River, Lyall.
