I regret much the not possessing the calyptra of this species, 
which in its leaves comes nearest perhaps to Polytrichum hercy- 
nicum, but in other particulars is very different. Indeed its quite 
entire leaves, (of which the texture is like that of the last-men- 
tioned species and P. undulatum and angustatum,) together with 
the narrow nerve, exactly ovate capsule and subulate lid, will 
keep it distinct from any other with which I am acquainted.
