perhaps in the field be separated with certainty. D. fluitans is 
autoicous, and generally fruits richly, while the present species is 
or quite perecurrent. The leaves in D. brachiatus are quite entire, 
while in D. fluitans they are frequently remotely denticulate in the 
acumen. In the present species they are often very lightly striate 
in the dry state; but they lack the plication of D. uncinatus, and also

the clearly defined group of small, numerous alar cells.

These plants agree quite well with the New Zealand moss, and 
manifest the same variations in habit, leaf form, and structure of 
nerve and areolation; while the fruiting characters are identical, 
of the base; in the two fruiting plants I possess of D. brachiatus, 
one from New Zealand, the other from Chiloe I., the point of the 
lid is very small, and the width of the lid is considerably greater 
than its height. 
It is unfortunate that Wilson’s name must give place to 
oi ’s, published two years earlier, since the former has been in 
large number of species, viz., Australia, Tasmania, New Zealand, S. 
Shetlands, Falklands, Patagonia, Peru.
