These specimens have leaves minutely serrulate all round, 
scarcely decurrent or very narrowly so at angles with costa 
from .o50 to .o60 mm. wide at base (about 4 width of leaf 
base) and extending 2 up. Median cells .co6 mm. wide and 
up to .130 mm. long. Cross section of stem shows 2 or 3 
rows of thickened cells in outer wall and a slightly developed 
central strand (798). 
fTypnum Wilsont Schimp. Middle of Lake Lebarge. 
The specimens I refer here are rather short (7 cm. high) with 
leaves a little narrower and less recurved than in typical 
specimens from Southport, Eng. The Yukon specimens are 
more like the specimens figured by Limpricht. All the 
specimens have leaves with very long, slender, flexuous or 
twisted points and scarcely decurrent angles. Sections of 
stem show 3 or 4 rows of thick-walled, golden-yellow cells 
next the surface and a central strand not always very dis- 
tinct (740). 
fTypnum revolvens Swartz. Dawson, common in swamps.
