is of peculiar interest since, notwithstanding its relatively large size 
and distinctive appearance, it has been very infrequently collected 
on this continent. Aside from the two stations noted the only Ameri- 
can localities from which it is known are the Gaspé peninsula, Quebec 
(J. F. Collins), the region bordering Lakes Huron and Ontario — 
in Bruce and Prince Edward Counties, Ontario (Macoun) and near 
Sandusky, Ohio (Lesquereux) —, and British Columbia (Macoun). 
It also occurs in Greenland and is widely distributed in northern 
Europe and Asia. Its apparent rarity in North America may be 
ascribed partly to the fact already suggested by Collins that the 
plants seldom form large mats, but usually occur singly or in small 
tufts intermixed with other species. In the Salisbury station, how- 
ever, although associated with other mosses, C. trifarium forms 
almost pure colonies of considerable size. It seems very probable 
that this is one of those forms like Anacamptodon splachnoides which, 
although widely scattered, is of extremely local occurrence. The 
frequent association of C. trifarium with Drepanocladus scorpioides 
has been referred to by Warnstorf! and Collins. In the present 
station also these two species grow together, forming loose mats 
in the wetter parts of the swamp amid a rank growth of sedges. The 
only other companion moss in the immediate vicinity is Chrysohypnum 
protensum. The Sphagnums are conspicuous by their absence. 
Since Calliergon trifarium is not referred to in Grout's recent 
Manual? a brief description is here given. The moss resembles 
somewhat a very robust Philonotis. The plants are golden-yellow 
above and glossy when dry, dark brown below. Stem rigid, erect 
or prostrate, simple or very sparingly branched, often 10-15 cm. or 
more in length. Leaves loosely imbricated, very concave, broadly 
ovate to suborbicular, entire, and very obtuse; nerve slender, usu- 
ally simple and disappearing above the middle, rarely short and 
double; basal cells large, mostly hyaline, and not forming a sharply 
defined group at the angles. Dioicous. Fruit rare, maturing in 
early summer.
