A variable plant, and hence the source of much of the above synonymy. 
The peristome especially varies in length, and in its shorter forms quite 
explains the reference to the genus T'richostomum by R. Brown of the 
above plants ; it is, indeed, placed in that genus by Jaeger. It is usually 
an abundant fruiter, and this, with the short red peristome only slightly 
bluntly pointed, the nerve strong below but rather thin and indistinct 
above, vanishi apex. 
Tortula incurvidens Stirton, of which I have examined the type in 
his herbarium, is simply one of the ordinary, shortly peristomate forms 
of this speci 
The So ak American plant from Chile, united by Mitten with this, 
has been separated on slight grounds of ‘difference under the name of 
B. Poeppigiana C. M.; a t in view of the evident variability of 
B. australasiae, together with its wide distribution, I am inclined to 
think the two will have to be reunited. 
B. australasiae is a common moss in New Zealand.

In spite of some considerable Meron in size and leaf-characters this 
is not a difficult plant to identify, from the bright yellowish-green tufts, 
reddish-brown below, and the leaves ns margins strongly recurved from 
base almost or quite to apex, strongly spirally twisted when dry (much 
as in the European B. wnguiculata)—in the denser forms so that the stems 
are terete, but in the Peet and longer leaved ones with the points usually 
sticking out—“ horride spiraliter torta.” The leaves are wider than in 
the last and more pointed, the nerve is stout and yellowish, becoming 
ct at the opaque apex, so that it is not easy to see where the 
lettin ceases and the nerve begins, but it appears to be usually percurrent_ 
(though no oe sometimes scarcely reaching apex), and is certainly at 
times distinctly excurrent in a short robust point. The upper cells are 
oe sa es rounded or quadrate, rather distinct, scarcely papillose ; 
while all the basal a re small, very narrowly rectangular or linear, pellucid,
