20 MR. W. MITTEN—-BRYOLOGIA OF THE SURVEY 
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 terminatis marginibus revolutis nervo it 
apice evanido, foliis perichztialibus late ovali-oblongis apice obtuse 
angulatis, cellulis elongatis teneris fere ad apicem usque areolatis, 
theca immersa ; cetera G. apocarpe similis. 
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 imbrieated; in their substance 
and areolation they agree exactly with those of G. apocarpa, and 
the capsule and peristome appear precisely the same; the peri- 
chetial 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. Müller.) 
G. LEvcoPH A, Grev. 
Hab. Fort Colville, Lyall. 
Rather 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. ACICULARIS, Linn. 
Hab. British Columbia, Lyall and Douglas. 
The capsule in some specimens elongated; but in other parti- 
culars like the European moss.
