This species is known from P. australe by the longer, larger, softer leaves, 
much crisped when dry, and closely and sharply toothed above; from 
QP, gi by the peristomate capsule and much smaller leaf-cells (10-15). 
Tt cecurs in mountainous districts of both North and South Islands, 
but is soon rarer than the next species.

The stems are ot than in the previous ei with the leaves very 
densely comose, shorter and much more rigid when dry, strongly incurved 
rather than crisped, and the margin is nearly or quite entire. It occurs 
throughout New Zealand in mountainous regions 
Both species are also found in Tasmania.

A aa age (see below), consisting of one magnificent species, 
having robust stems sometimes 14 ft. high, simple for the greater part of 
its length and naked cabent for a few appressed scale-like leaves, in the 
upper part dendroidly ramose inte numerous branches several inches long, 
more or less densely foliate with very long leaves much crisped when dry. 
he fruit is terminal on one or more cf these branches (sometimes pro- 
longed later so that the fruit appears lateral), with setae 2 in. long or more, 
and capsules resembling those of Polyirichum alpinum, but with calypt 
glabrous or nearly so. e nerve has numerous low, not sinuose lamellae 
on its upper surface, and 2--3 toothed lamellae at back.

One of the finest of the New Zealand = and, I gather, widely dis- 
tributed. It varies considerably in length of branches and leaves. It is, 
I have no doubt, either one of the short, dense forms of rat or a poly- 
cephalic state of a ytrichum, which Mitten referred to Polytrichum 
squamosum f. & W., a Fuegian plant not otherwise Bank from New

Jupp’s at Kew, nor in Mitten’s herbarium at New York. A plant of 
Hector’s (62, Og, a is not at all tnlike the a moss, but is 
from D. dendroides. Abnormal states of several species of Polytrichum 
occur, such as P. alpinum and P. commune (it is, no tne such a state 
of the latter na that Hees given rise to the erroneous re dro-
