BRITISH JUNGERMANNIiE. 
( J. barbata.) 
Caiyptra ovate, delicate, reticulated, and tipped with a short tubular style. 
Pistilla numerous, lanceolate, a little swollen at the base, and slightly expanded at the mouth. 
Peduncle from three-fourths of an inch to one inch in length, white, succulent, cellulose. 
Capsule dark brown, ovate, approaching to spherical, opening into four, or sometimes, 
according to Schmidel, three valves. 
Seeds and spiral filaments deep fulvous brown : the former spherical ; the latter formed of 
a double Helix. 
Gemmae are produced both on the common appearance of the plant, and more abundantly on the 
var. (3. On the former, I have always observed them to be collected into small spherules (f. 16) : 
in the latter, to be loosely scattered at the apices of the leaves. In both, they are of a roundish 
figure, beset with sharp angles, of a greenish brown color, semipellucid. 
My var. (3 (f. 18) is considerably smaller than %, rarely exceeding an inch in length, notwithstanding 
that the upper half is usually lengthened and ascendant. This part is covered with leaves so 
closely imbricated on each side of the stem, and appressed to it, as to conceal it altogether, and 
make it bear no inconsiderable resemblance to the shoots of J. consinnata : while the lower 
leaves are patent, as in the common state of the plant. The leaves, however, throughout, 
are more concave, and the color much browner. The uppermost leaves are notched, forming 
three, and sometimes only two, small teeth (f. f. 19- 20). On these the Gemmce are situated. 
The leaves below them are frequently antheriferous. So small are the stipules, that they are 
with difficulty discoverable; and they will be found to be rather ovate than lanceolate, whilst the 
margins are nearly intire. Unfortunately, no Female Fructification has been yet met with, 
by which it might be ascertained how far I have done right in making the present plant a variety 
of J. barbata, for it differs in many particulars ; and I am not aware, that the common appearance 
of this species has ever been found in our flat parts of England ; it being confined, as I have 
reason to think, to somewhat mountainous districts. 
Notwithstanding that the figure 23, t. 71, of Dillenius has been generally quoted as the 
J. tribolata, it is really intended, as well as figure 22 of the same plate, for the plant here 
described, if any dependence can be put in the specimens corresponding with those numbers in the 
Herbarium at Oxford. Micheli’s representation of this species is particularly unsatisfactory : that 
of Schimdel, in his hones, as well as his elaborate description, are truly from the hands of a 
master, although he has fallen into the same error in common with the other botanists who have 
described this plant, all of whom, with the exception of Dillenius, have omitted to notice the 
stipules. I am much surprised that they should have escaped the acute researches of Wahlenberg 
and Mohr. These naturalists have, it is true, discovered them on what I consider to be the same 
species, the J.Fldrkii; for nothing can better correspond with our present species than the 
description of it in the Flora Cryplogamica Germania;: “ Foliis inaequaliter tridentatis, cseteriim 
integerrimis : amphigastriis (our stipulesj 2-partitis, laciniis subpinnatifidis.” Yet, although 
Wahlenberg refers to Mohr’s description, he has represented the plant as having simple stipules.
