BRITISH JUNGERMANNEE. 
(J. tomentelia.J 
Female Iructification in the axillae of the primary divisions of the stem. 
Calyx (t. f. 5. G) nearly a line and a half long, oblong, cylindrical, a little increasing in 
size towards the mouth, which is expanded and entire; its whole substance firm and 
subcarnose ; indeed, as much so as that of the stem, with the nature of which it seems to 
agree. It is of a yellowish-brown color, and is, on its exterior surface, beset with those 
capillary branched processes, which I have described above as the perichaetial leaves: 
these form at the mouth a minute kind of fringe. 
Calyptra none, (see f. G.) At least, in the only specimen of the calyx that I had an oppor- 
tunity of dissecting, 1 was not able to find any. It may, however, have been an injured 
one: yet I am acquainted with two foreign species of this genus that have, like the 
present, the perichaetial leaves arising from the calyx, in which I have universally found 
that t he calyptra was wanting; a circumstance that tends to confirm my belief that the 
germen is here likewise destitute of that part. 
Peduncle one or even two inches in length, striated, and often slightly twisted, fixed 
into the receptacle by means of a small obconical bulb, and terminated bv the 
Capsule, of an ovate shape, and deep purplish brown color ; dividing at maturity into four 
equal valves. 
The seeds and spiral filaments (f. 8), which I have only seen from an imperfect capsule, are 
of a fulvous color ; the former spherical, the latter composed of a double helix. 
J. tomentella is readily enough distinguished in its place of growth, from every other 
species, no less by its very pale color, than by the extent of ground occupied by its tufts. It 
bears considerable affinity with the J. ciliaris of Linnaeus ; but, besides the great difference in 
color- (J. ciliaris being always more or less of a rich yellow-brown), our present plant is much 
less convex in the upper -u: face of its leaves, which are diiided into far narrower segments, and 
the lacinise are considerably longer, and more numerous, as well as greatly more branched, than 
is the case with that species, in which, moreover, the stems are almost always procumbent. In 
the Banksian Herbarium, as well as in Dr. Smith’s and Mr. Turner’s, are preserved specimens of 
a Jungermannia from New Zealand and the Sandwich Isles, so closely allied to this, that I cannot 
do otherwise than mention it as a variety, and, indeed, I am unable to point out any difference, 
except in the ramification, which in the exotic specimens is simply pinnate, and in that respect 
approaches in its mode of branching to Ilypnum Crisla-castrensis , infinitely more so than J. to- 
mentella does, as oberved by Weis. 
Dillenius justly says, when speaking of the figure of this species in Vaillant, ,f nec ramos 
nec folia et eorum villum bene representat indeed, it bears a much nearer resemblance to 
J. fucoides of Swartz’s Flora India Occidentalis, than to our species. It was reserved for the 
author of the Historia Museorum, to represent with great correctness this interesting plant, and 
his description is scarcely le-,s accurate. “ Rami secundarii,” he observes “nervos tenues habent 
et foliolis frequentissimis vestiuntur, primarii verb, seu caules, pro plantse ratione crassi sunt,.
