246 BRYOLOGY OF NEW ZEALAND. 
from R. Brown’s herbarium, unnamed. In habit it is somewhat inter- 
mediate between the ie preceding species and C. tenella, being more 
slender than the former, more rigid, less branched. In the toothed 
perichaetial leaves it resembles C. confusa, but differs from both that 
and C. dilatata in the leaves, which are narrower, more elongate, with 
a narrower, pnp often half-twisted point ; the margin is widely 
recurved when icine ha nerve deeply carinate, generally more 
tapering cise: and ceasi little way below. the apex; the 
leaves are more or less jou pibuaitintly plieate. In C. eae pig and C. 
confusa the leaf margin is recurved when dry, but or seareely 
when moist. The A rede is delicate and fragile, me teeth and 
processes narrow, oth.

An aquatic or semi-aquatie species, like C. dilatata and C. 
confusa, but of very different pee Apert dull, dark green, with 
shorter, very rigid stems, which are not much bra nehed, but are 
usually densely clad with the perichnctizt beauenes! which are gener- 
ally homomallous, often set in two ranks. 
The leaves are almost exactly as in C. dilatata, but the margin is 
quite plane, while there it is often very slightly reflexed close to 
the base. I do not find the alar cells empty and thin-walled, as 
Brotherus describes them ; in the type specimen, leg. Archer, in herb. 
Mitt., they are opaque. The perichaetial leaves are denticulate at. 
margin, but less strongly so than in C. confusa. 
In addition to these vegetative characters, C. tasmanica has mark- 
robust and regular, with firm, fully developed outer teeth, which are 
thicker in texture, lee with strong lamellae, internally markedly 
prominent. 
I have examined Colenso’s C. novae-zealandiae (Col. No. 4217 in 
Herb. Kew.). ean find no erences to separate it from C. tas- 
manica , and indeed the description searcely suggests any specific 
difference, except perhaps that the nerve is said to extend to the apex; 
but olenso’s specimen that’ is not the case; the nerve ceases just. 
pos the tip as in C. tasmanica. 
C. tasmanica oceurs in both Islands, and also in Tasmania.
