Very nearly allied to the European D. compacta Sch., from which it ae 
by the leaves being more narrowly acuminate and generally subacute, the 
cells of the areolation larger and with thinner walls, and chiefly by the costa 
narrower, attenuate below (16 to 25u broad; it is 554 in D. compacta).— 
Along the trail from Holzinger’s basin to the Rim.

This very minute species, resembling in habit the small forms of Andreea 
Petrophila, is quite distinct from all the European and North American species 
of Grimmia with muticous leaves by the small size, and the shape and areola- 
tion of the leaves,— Base of Sperry glacier; Mt. Trilby. 
GRIMMIA MOLLIS B.S.—This European alpine moss is reported 
from Greenland, and should be found at intermediate stations in 
Canada.— Base of Sperry glacier.
