Although in external appearance, colour, and habit, this plant 
looks very different from Sh. sguarrosum, and is so regarded by 
most of the leading bryologists, it will be found on careful examina- 
tion to present not a single point of structural distinction, by which 
they can be separated. 
The plants are shorter and of denser habit, but the perichetial 
and stem leaves, although a little narrower, agree precisely in areo- 
lation ; the branch leaves indeed are ordinarily not squarrose, but 
we constantly meet with stems which have the lower branches 
more or less squarrose-leaved, while the upper retain their normal 
direction, and if we examine growing tufts of the plant, it is quite 
common to find the central stems normal, while those at the cir- 
cumference of the patch have all their branches squarrose-leaved. 
The dioicous inflorescence and the elongated sterile termination to 
the antheridial branches are the sole differential characters. 
It also resembles the robust forms of Sp. acutifolium, but has 
stouter and more closely imbricated branch leaves, and the stem 
leaves are quite distinct. 
Professor Lindberg has pointed out that, like sguarrosum, the
