certainly only a robust form of pee conicum Mitt. C. Mueller 
writes of it, “ welche ganz wie P. turbinatum aussieht, aber eine calyptra 
dimidiata hat.” The specimens in Schimper’s Riechavtucs have only a single 
poreed dear but that is not dimidiate, but distinctly that of Physcomitrium 
- Mueller may have been misled by an immature calyptra, or a 
had no intention of relating this to the Funaria physcomitrioides Mont. 
from southern India; the name was duplicated simply through a slip of 
memory. 
BRYACEAE. 
The New Zealand genera of this great family may be distinguished by 
the following key :-— 
1 Fruit from base of stem ; peristome more or less imperfect ..  Mielichhoferia. 
* | Fruit terminal ; peristome mostly well developed > 
f Basal membrane of endostome wan oe or not reaching above 
2. d orifice ; outer peristome shorter than inner Orthodontium.

Capsule more or less erect or inclined; processes of endostome 
4. usually rudimentary ; cilia O oy Brachymenium. 
Ca eon more or oe ndulous ; processes normal he 5 
5. linear or narrowly linear-rhomboi ; 
Cal rhomboid ee rhomboid-hexagonal a = .. Bryum. 
6 aves more or less acute and spreading ig ems 
: ee obtuse or subobtuse, slay imbricate and terete -. Anomobryum. 
It should be noted that the se between ne and Pohlia is 
not oe clearly defined, and the clause 5 above may be mislea ading ; in 
F ans, sea to some extent in °P. tasmanica, the cells are wider and 
Bryoid.
