328 ON SOME BRITISH MOSSES. 
- 
portion is carinate, the margin slightly recurved below, above it is 
remotely and irregularly denticulate, the nerve is continued into a thick- 
ened, obscure, blunt point, which has so great a tendency to break off 
that in some specimens it is not easy to find a perfect leaf ; when dry, 
the foliage is twisted and contorted \ its fruit has not yet been found. 
In Sussex this Moss grows about the roots of trees in shady places, 
at base of the chalky hills. Mr. Borrer gathered it in Cornwall, and 
Mr. Wilson near Bangor.

uncommon in England, rarelv occurring in fructification ; it is found, 
also, in the south of Ireland, but I have seen no specimens from Scot- 
land. 
First characterized as a distinct species by De Notaris in 1838, in 
the description above given, it has since by himself, — probably in de- 
ference to the authors of the ' Bryologia Europrca/ — been redescribed 
and figured in 1862 as T. vinealis, Brid., but from this it (lifters in 
the long, narrow leaves spreading in all directions, recurved or uncinate, 
from an erect base, which is appressed to the stem and has erect mar- 
gins; in a dry state the foliage is cirrhate. 
There is another British Moss which, although not referable to the 
particular group now considered, is very frequently represented in 
Herbaria by T. insulana, it is the Ancectangium Hormcliuchianum of 
Taylor in Fl. Hibernica ; the only specimens of which that I have 
seen are those given me by the late Dr. Taylor himself; as this species 
is perfectly distinct from Anoectavgium Hornschuchiannm (Gyvmosto* 
mum), Iloppe et Hornsch., and although more nearly resembling 
Didymodon cylindricuH, B. et S., is certainly a different species, I pro- 
pose that it should be called
