Hypnum Jluitans L. In swamps near Marsh Lake. 

 These specimens have leaves minutely serrulate all round, 

 scarcely decurrent or very narrowly so at angles with costa 

 from .050 to .060 mm. wide at base (about \ width of leaf 

 base) and extending f up. Median cells .006 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). 



Hypnum Wilsoni 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). 



Hypnum revolvens Swartz. Dawson, common in swamps.
