This species is, as stated in the Handbook, not distinguished from 
the last by any de finite structural characters. It is, however, k, 
quite a good species, and IJ have rarely found any diffieulty in separ- 
ating the two. It is Jig Se a smaller plant with denser branching, 
the leaves narrower above, quickly contracted to a short, acute 
point (the Handbook deseviption of the leaves as acuminate is rather 
misleading) ; they are generally more regularly imbriecated, and are 
not at - altered when dry. The seta is perhaps slightly longer. 
C. ramulosa produces many forms, oe os to those of C. 
debisiiasta. It appears to be equally comm 
5. Camptochaete angustata ( Mitt.) oe Adumbr., ii, 214. 
Syn. Stereodon angustatus Mitt. in Journ. Linn. Soc., Bot., iv,

This is very similar to C. ramulosa in habit, but rather more deli- 
eate in all its parts; the branch leaves are much narrower, lanceolate, 
nd taper gradually to an acute point. The fruit also when present 
is smaller, and the whole plant has a lighter and more delicate habit. 
It differs from C. ramulosa, in fact, in precisely the opposite direction 
from C. arbuscula. The fronds are frequ ae more or less compla- 
nate, and in that case the contrast between the larger, becuase stem 
leaves and the narrower and delicate foliation of the branches is 
avin but this does not by any means always occur. The alar 
ae are more numerous and more seine than in the allied species. 
A parallel form to ‘the var. deflexa of C. arbuscula oeeurs; and 
forms with delicate, flagelliform heasaniets are not unfrequent. 
I, obscurum Col. certainly belongs here; Brotherus ae written

Taken by itself it would seem well worth a varietal name, but in that 
case the ‘ detivustives of C. arbuscula would equally demand one, pro- 
pore to be followed by the other species of the group, and it is more 
correct, I think, to consider them all as forms, or perhaps more accur- 
ately eats, of the respective species 
I have also received a form exactly corresponding to the var. 
deflexa of C. arbuscula (Berggren; Lyttelton, No. 1639); but in this 
ease forming pari of a gathering the bulk of which showed the nor- 
mal, dendroid habit. 
angustata seems, like the two preceding species to be widely 
distributed, but unlike them is not found outside New Zealand.
