folius type is the only species at all likely to be confused with it, ‘and that 
differs, as has been pointed out, in the shorter stems, more rigid leaves, 
more shiosophy lions cells, and axillary male flowers, F. asplenioides being 
divicous, 
It is probably much more common in the North Island, but I have a 
specimen from as far south as Dunedin.

This is the finest of the New Zealand species, and of very wide but 
rather peculiar distribution, as it is almost universally spread throughout 
the Northern Hemisphere, but in the Southern it is confined to New 
Zealand, Tasmania, and possibly southern Australia. I do not think

I have accepted the commonly received view, that the New Zealand 
plant is different from the South American Conomitrium Dillenia Mont. ; 
but in that case the Australasian distribution of the latter plant (as given, 
e.g., in Par., Ind. bryol.) should be excluded. 
C. Miller gives the name C. aciculare to the New Zealand plant (citing 
C. Dillenit H. f. as a Sony ny but this does not differ in any way from 
the Australien F. Miiller 
The plant is a aati distinct one in its aquatic habit, filiform, 
flaccid stems, and distant, blackish, long, narrow, and straight leaves 
The fruit is very minute on a very short seta. 
The species appears to be rare in New Zealand. 
INCERTAE SEDIS. 
Among some plants of F. inclinabilis which I received levi Mr. D. 
Petrie, co aay near Dunedin, I detected a few stems of a Fissidens, 
apparently of § Bryoidium, totally distinct from any Australasian species 
Ww. ich 1 am acquainted, having wide, broadly pointed leaves narrowly 
but distinctly bordered, with a narrow straight nerve, and the areolation 
very lax and absolutely pellucid, of regular, hexagono-rounded empty 
lis; and producing numerous large, green, elongate, jointed propagula 
among the leaf-axils. I have not found any fruit. It is without any
