I have examined from two other localities in Maine; Hebron (Mrs. 
Stevens) and Orono (Fernald). 
Hypnum RicHarpsonu, (Mitt.) L. & J. Man. (Stereodon Rich- 
ardsonii, Mitten.) Collected July 16, 1902, in a mixed cedar swamp, 
. Fort Fairfield, Maine. In leaf characters this agrees very closely 
with specimens from Styria, Austria (Breidler), Norway (Lindberg) 
and North Wakefield, Quebec (Macoun). It has somewhat larger 
leaves than Dr. Richardson’s plant from Great Bear Lake. In gen- 
eral habit, however, it does not agree as closely with the specimens 
mentioned above as with some collected at Houlton, Maine, in 1899 
(J. F. C.) and at Barnet, Vermont (Dr. F. Blanchard) in 1886. 
The three New England stations here mentioned are the only rec- 
ords of the plant in the United States which have come to the 
writer’s notice. The Vermont station was published in 1898.! Æ. 
Richardsonii is closely related to 77. cordifolium. ‘The former differs 
in the somewhat pinnately arranged short branches of the fruiting 
plant, in the shorter costa, the abruptly enlarged alar cells and usu- 
ally in the cuspidate or tapering tips of the stems and branches, 
due to closely imbricated leaves. ‘The two last mentioned characters 
have been noticed occasionally in Æ. cordifolium. 
i MNIUM CINCLIDIOIDES, (Blytt) Hüben., often varies from most of 
the published descriptions in having slightly margined leaves, fre- 
quently with distinct, obtuse teeth. Costa sometimes percurrent. 
CATOSCOPIUM NIGRITUM, (Hedw.) Bridel. Collected by E. F. Wil- 
liams, M. L. Fernald and the writer in the gorge of the Aroostook 
River, New Brunswick, July 17, 1902. The specimens were finely 
fruited though not very abundant. This species has been reported 
from several places in British North America ? but, so far as known 
to the writer, from only one locality in the United States (Montana) 3. 
Anticosti Island, more than 250 miles to the northeast appears to be 
the previously reported station nearest to the one here mentioned. 
The gorge of the Aroostook River is within two miles of the eastern 
border of Maine, so that the finding of Catoscopium there is of special 
interest to students of the New England flora. Catoscopium nigritum, 
with its tiny, horizontal, dark capsules, is a well marked species of
