In mountain woods. (Fr. Mar. Apr.) 



Growing in dense matted tufts, 2 or 3 inches 

 broad, firmly attached to the soil. Stems ascend- 

 ing, or when crowded erect, seldom more than three 

 or four lines long, simple, 

 with innovations, dirty 

 green (fig. 103). Leaves 

 in two opposite rows, 

 horizontal, rather closely 

 imbricated, entirely con- 

 cealing the stem, smaller 

 at the base, somewhat 

 rounded, divided about 

 half way down into two 

 unequal vertical lobes ; 

 the inferior the largest, 

 oblong, a little curved on 

 one side, thus scimitar- 

 shaped ; the superior 

 ovate or oblong-ovate, 

 closely adpressed diagonally to the larger lobe, 

 both obtuse at their apices, and rounded, margins 

 entire, except in a few terminal leaves, which are 

 microscopically crenate. Perichaetial leaves larger 

 than the rest, more erect, a little waved at the 

 margins, enveloping the lower part of the calyx, 

 which latter is ovate or obovate, erect, plicate in 



103.
