tendency to assume the folded form as in Scapania so that many 

 consider the leaves two-lobed with the lobes toothed. The 

 plants are smaller than in barbata and usually grow on de- 

 caying wood. 



Our other species of this genus (except some very rare or 

 alpine forms) have two-lobed or two-toothed leaves and are 

 more likely to be confused with Sphenolobus.

ODONTOSCHISMA. 



Leafy stems T V inch or less wide, creeping and interwoven, 

 green, to red-brown with a trace of green ; branches usually rising 

 from the underside of stem; leaves entire, rarely emarginate or 

 bilobed, often bordered. Underleaves invisible with a lens. The 

 perianth is on a short lateral branch which distinguishes all the 

 species from Jamsoniella. 



O. PROSTRATUM (Swartz) Travis (0. Sphagni of American 

 authors). The plants of this delicate and pretty hepatic grow 

 mostly in swamps over and among mosses and other bog plants, 

 rarely on rotten wood. The stems are creeping with ascending 

 tips; leaves distant to closely imbricate, not growing minute at 

 base and apex of branches, attached very obliquely, not flat- 

 tened out but ascending and forming a channel between the two
