The /alk is erett, from two to three inches high, and rather 
naked at the bottom.—The /eaves are fpreading, linear-lanceolate, 
and ending with fharp points, flightly hifpid: their edges are en- 
tire, and eid in flat upon the furface of the leaf from both fides.— 
The peduncle varies from an inch and half to about three inches i in 
length, and is clofely furrounded at the bafe by a cylindrical tube or 
perichatium, which is about a' quarter of an inch long, iffuing from 
the top of the ftalk.—The cap/ule is quadrangular, with an apophy/is 
at the: bafe ; the operculum is flat but pointed in the centre, and the 
rim is fringed with a regular row of about fixty-four whitifh dents. 
—The exterior calyptra is long and fubulate, whitith at the bottom, 
but ferruginous at the tip, and about double the length of the in- 
ner one. 
All authors I know of, who have taken up P. juniperinum, de- 
fcribe it with entire leaves, yet make no f{cruple in quoting for it 
Dill. Mufe. 424. t. 54. f- 2. which that accurate author defcribes and 
figures with ferrated leaves : it is therefore very evident the quo- 
tation muft be erroneous. 
Note. The Polytrichum pulverulentum in Gmel. Syft. Nat. belongs, I believe, to this 
fetion; but as I have not been able to procure a fight of the plant itfelf, or even of the 
figure of it, quoted from Reynar, AG, Laufann. 1 could not take it up in this Arrange- 
ment.
