employs this term where the plant is really synoicous, and this may be the 
ere. 
The other two species placed in the synonymy certainly belong here, 
from an examination of Brown’s type specimens. 
B. affine is probably quite as frequent as B. bimum.

This plant is distinguished by its autoicous inflorescence, the rather tall 
and laxly foliate stems, with the leaves somewhat contracted and twisted 
when dry, the wide border and strongly recurved margin, longly excurrent 
nerve, long seta (up to 4¢ c. 
B. Maudii R. Br. ter. is a the same thing. It isa plant of marshy ground. 
It was also gathered in the Mount Cook district by Mr. James Murray in 1907.

I have no doubt that the specimens so named by Wilson belong to this 
species, and ave seen several tees Pearce referable here, including 
the type of B. cylindrothecum R. Br. 
It has the densely tufted ie See of the group, and is 
usually fairly easily recognized by this and the densely crowded leaves, 
erect and little altered when dry, narrowly acuminate with strongly recurved, 
rrowly bordered leaves, and longly excurrent nerve. The dioicous in- 
florescence wil] separate it from small forms of the last species, the pale 
b ot red or purple) capsule from most of the species of the same 
B. austro-bimum Broth. is the nearest to it, with the same habit 
and similar fruit, but has decidedly wider leaves with shorter points, the 
nerve stout and red at the base.

I have received from Dr. Brotherus a part of the type gathering of ~ 
which appears to be a quite distinct though not sens marked species, 
very nearly allied to B. caespiticium, but hed by the Cases 
iven above. I know of only one other record besides the original one 
from Mount Alfred, coll. W. Bell. This is a plant in Hooker’s herbarium at 
Kew, determined as B. caespiticium, var., ‘‘ N. Zealand, Colenso, 4665, Hb. 
Hook.”

It is scarcely necessary to describe this well-known and cosmopolitan 
moss, which cannot be mistaken for any other species
