In boggy places, Scotch Highlands. 



Stems two to four lines high, by a line in 

 breadth, of a brownish colour, slender, rigid, 

 flexuose, of a dense texture, naked, or a few scanty 

 white rootlets. Barren shoots 2 to 4 inches high, 

 simple, or with occasional innovations from the 

 axils of amphigastria. Leaves nearly uniform, 

 subvertically imbricate, appressed, obliquely or- 

 bicular, or reniform, entire, or obscurely truncate, 

 very concave, ventral border rounded, and inserted 

 at right angles to the stem, anterior narrow and 

 decurrent. Colour uniform straw, or pale olive 

 green. Amphigastria rare, except at apex of young 

 shoots, long and slender, subulate, erect. Inflo- 

 rescence dioicous. Andr^ecium spicate, terminal. 

 Perigonial leaves more rounded and convex, 

 gibbous at the base, posterior lobe subquadrate, in- 

 flexed. Antheridia two to three in each leaf, round, 

 or obovate. 



At first sight resembling N. coinpressa, but quite 

 distinct, which is supported by the cell structure.—
