which is the largest. The texture of the leaves is rigid and brittle when dry ; the 
cellules, which are of a roundish figure, are distantly placed, yet somewhat regularly, 
in longitudinal lines (f. 9). The color is a pale yellowish brown, inclining to olive in 
the Scotch variety. 
Perichcetial leaves (f. 10) larger than the rest, and proceeding, as it appears to me, from 
all sides of the stem : the divisions of these leaves too are more numerous, frequently 
six or even seven, their margins more recurved, their teeth larger and more abundant. 
In other respects they exactly agree with the cauline ones. 
Male Fructification unknown. 
Female Fructification both terminal and lateral. 
Calyx (f. f. 5. 11) nearly a line in length, oblong, plicate ; the mouth toothed, but not at 
all contracted ; the texture thin and rather delicate, much more so than that of the 
leaves ; the reticulation small ; the areolce oblong ; the color a pale yellow brown. 
Calyptra obovate, reticulated, white ; style rather short, slender, and tubular. The 
barren pislilla are numerous, situated at the base of the calyptra : each is linear, 
swelling out a little in the middle, its mouth slightly expanded. 
The Capsule I have only seen within the calyptra, at which period of its growth it is 
exactly spherical, and of a deep olive-green color. 
That the two plants here figured belong to one and the same species, I believe there w T ill be 
found no reason to doubt. My variety /3 differs from a. only in being smaller and of a more 
olive-green color, and in having the segments of the leaves entire. The drawing of a I have been 
under the necessity of making from foreign specimens: for this, I trust, no apology will be 
considered necessary, as I could not otherwise have represented the fructification, which is now 
described for the first time, though my description has been taken from the very specimens 
gathered in Lapland by Linnaeus, who, in his own account of the plant, leaves the fructification 
unnoticed. The Lapland specimens, it may be remarked, as well as the German, and probably 
the French ones, too, are found in woods, whereas our British plant inhabits the highest of the 
Scotch Alps ; and this difference in the place of growth may perhaps be considered as a cause in 
some measure of the different appearances they put on. From Dr. Swartz, also, I have been 
favoied with fructified specimens, exactly agreeing with those here figured. 
Ehrhart, who first discovered J. setiformis in the Hartz Forest, in Germany, justly remarks 
that the leaves are so deeply divided, that each individual may be taken for four separate 
leaves: but I cannot agree with that author in thinking that the segments are so strongly 
furrowed on the back as to represent in miniature a leaf of Fontinalis antipyretica. He farther 
adds, that he knows of no other plant which has such a peculiarity in the leaf. 
There is m the general habit of this plant, particularly in the mode of growth, a considerable 
affinity with J.julacea. In both the leaves are rigid and brittle, and those, which clothe the stem 
of the former, correspond very nearly in figure with the pericheetial ones of the latter. The form 
of the calyx is the same in both, as is also that of the capsule.
