Polyoicous. Stems creeping, the apex only ascending, innovant, 

 ramuli dichotomo-fastigiate, clothed beneath with numerous claret- 

 coloured rootlets. Leaves loosely and bifariously imbricated, lower 

 ones obliquely explanate, upper erecto-patent, roundish, sub-mar- 

 ginate, repand-undulate, decurrent ; involucral leaves broader, ap- 

 pressed to and surrounding the colesule, with the lower third of 

 which one of them is connate ; colesule obovate, sharply plicate, the 

 angles rough, somewhat exserted, rostellate, at length quadrifid; 

 capsule rouudish-ovate.

Forming more or less dense, depressed tufts, on wet slaty rocks, or intermingled 

 with bog mosses ; remarkable for the crystalline, glaucous-green, semi-pellucid foliage, 

 and reddish rootlets. 



Shoots (f. 36, 1) from a quarter of an inch to an inch long, by 

 j^" to ■^" in diameter, procumbent or erecto-procumbent, densely 

 radiculose, simple or innovant ; ramuli springing from the axils 

 of the involucral leaves, causing the colesule to appear lateral, but 

 more commonly from the ventral aspect of the stem, simple or 

 dichotomo-fastigiate, geniculate at the base, ascending, 



Mootlets more numerous, and of a- paler claret or reddish colour 

 than in N. obovata, in some shoots almost colourless. 



Leaves (f. 36, 2) i^" to -aV long, laxly disposed, semi-vertical, 

 roundish, sometimes broader than long ; broad and obliquely de- 

 current at the base, plane and nearly horizontal, except on the upper
