242 BRYOLOGY OF NEW ZEALAND 
e New Zealand plant differs in no respect from that’ of the 
noenetit hemisphere. Stress is laid in the description (Trans. N.Z. 
frequently, perhaps pagrree is the case with our British plant. It 
of 
is one those case “i e Saelania, where a plant of the northern 
hemisphere appear in Naw Zealand with no further distribution 
in the Southern Hoinispliee: 
CRYPHAEACEAE. 
e species united under Cryphaea by the older writers are 
divided by Brotherus into several genera in the ‘‘Musci,’’ and the 
pe Zealand species fall into three of these, Cryphaea, Cryphidium 
flower and Sy inectey the se aaa terminal on a shorter or 
longer branch having foliage leaves at its base, while in Cryphaea 
the perichaetia are sessile on the stem or brane hes. A glance at the 
y phi- 
dium Muelleri (Hampe) there is no such difference; the perichaetia 
are similar and similarly placed to those as figured for e.g. Cryphaea- 
protensa and C. attenuata; and the same is the case with Dendrocry- 
phaea tasmanica, or even more so; for in C. dilatata and other species 
striking features of sis ecies. I prefer therefore to keep all the 
species under Cryphae. 
Fleischer coe Wy, pp. 280 sqq.) in revising the genera in 
C. Mueller’s herbarium, separates Cyptodon Par. & Se himp. from 
i phidium (Mitt.) Jaeg. (which Brotherus had united), since the 
of Cryphidium (Mitt. ) belongs to the Leptodontaceae; the Aus- 
eis asian species are retained under A at ate If the New Zealand 
species placed by Brotherus under Cryphidium are to be tk 
from Cryphaea, they must therefore ha placed under Cyptodon 
Key.
