A very pretty species, especially when (as is usually, perhaps, the case) 
the whole plant is coloured a deep vinous red. Most of the specimens I 
have seen are the male plant, with the flowers discoid and conspicuous as 
in P. albicans, which is a much larger and very different plant. 
The cells, although very narrow as compared with those of P. albicans, 
are wide as compared with all the other species (except probably P. nutanti- 
polymorpha), and are pellucid and thin-walled. 
Bryum Binnsii R. Br. ter. must be referred here, though the leaves on 
the main stems are slightly wider and less finely-acuminate. is a t

a misprint). From the description and figures the capsule probably differs

Brown records it from Stewart Island, and from Dunedin, where it was 
collected by Miss : i 
in the South Island (coll. James Murray, 1907); but I do not know of any 
other New Zealand records beyond those given by R. Brown for B. Binnsit. 
It was first described from Tasmania, and has no wider distribution.

Distinguished from Bryum principally by the fruiting characters, the 
capsule being erect or inclined, rarely horizontal or pendulous, the mouth 
small; while the inner peristome is imperfect, consisting of a more or less 
elevated membrane, and processes which may be fairly developed or entirely 
rudimentary or wanting, without cilia.
