JUNGERMANNIA FEMBRIATA. 
Jungermannia caule elongato erecto subsimplici squa- 
moso, foliis densissime imbricatis distichis squarroso- 
recurvis bifidis, segmentis ovatis cuspidatis ciliato-spi- 
nosis, stipulis bifidis segmentis lanceolatis recurvis 
ciliato-spinosis, calyce terminali oblongo plicato.

Caulis 3-4-pollicaris, erectus, flexuosus, rigidus, squamosus, 
squamis parvis angustis laciniatis, simplex vel prope apicem 
per innovationem divisus. Folia fusco-lutescentia, densissime 
imbricata, disticha, squarrosa, semiamplexicaulia, undulata, 
late ovata, bifida, segmentis equalibus plerumque recurvis, 
cuspidato-acuminatis, marginibus recurvis elegantissime ci- 
liato-spinosis. Substantia compacta, reticulis minutis. Sti- 
pule magne, ovate, bifide, segmentis recurvis cuspidato-acu- 
minatis, marginibus recurvis, ciliato-spinosis. Calyx termi- 
Nalis, vel per innovationem caulis lateralis, oblongus, plicatus. 
This and the immediately preceding species of Jungermannia 
(J. squarrosa), though coming from very different parts of the 
world and from totally different climates, have nevertheless a 
very great affinity with each other in the mode of growth, colour, 
the svaly stalk, the texture, and the general form and direction of 
the leaves and stipules. The principal points of distinction be- 
tween them will be found to be the much smaller size of J. fim- 
briata, and its having the leaves ‘and stipules narrower and 
more deeply cleft, with their segments recurved and their margins 
most beautifully ciliated.
