ameter. Annulus of two rows of cells. Teeth of peristome 
hyaline bordered, papillose above, outer plates striate, inner 
lamellae about 30, segments without rounded perforations, 
more or less split along the keel with mostly 2 appendiculate 
cilia between. Seta rough throughout, up to 1.2 cm. high. 
Smooth spores up to .o1r mm. (Plate 23.) 
Dawson, on rock. In good fruit June 24, 1898 (722). 
This species is evidently nearest suberythrorrhizon but dif- 
fers in the rough pedicel, leaves narrower, less serrate and 
plicate and cilia appendiculate. 
Brachythectum erythrorrhizon B. & S. Dawson, on 
earth, common. Leaves always more or less falcate-secund, 
thus resembling ve/u¢enum more perhaps than any other of 
the genus (721). 
Cirriphyllum cirrosum (Schwaegr.) Grout. Skagway. In 
thick mats on rock by stream. Collected in rather old fruit, 
August 27. These specimens have stems up to 11 cm. long. 
A few of the capsules still retain the lid which is acutely 
conical, a little higher than its basal diameter. The seg- 
ments are separated by 1-3 long, nodose cilia. Not before 
reported with fruit in North America (794). 
Eurhynchium strigosum (Hoffm.) B. & S. Dawson, com- 
mon (725). 
Eurhynchium stoloniferum (Hook.) Jaeger & Sauerb. 
Cafion City, Dyea Creek and Skagway (724). 
PoROTRICHUM NECKEROIDES (Schwaegr.) Williams. 
(Thamnium neckeroides B. & S.) 
Cafion City, Dyea Creek. Lower stem leaves nearly as 
broad as long, entire or nearly so, with rounded apex. Costa 
rather coarsely toothed above on back in the upper leaves 
(726). 
Plagiothecium piliferum (Sw.) B. & S. (Hypnum trich- 
ophorum Spruce.) Skagway, Cafion City and Lake Linde- 
man. In very soft, often thick cushions on rock (727). 
Plagiothectum pulchellum (Dicks.) B. & S. Lake Marsh 
and Dawson. Common on earth and rock (728). 
Plagiothecium denticulatum (L..) B. & S. Head of Lake 
Bennett and Dawson (729).
