BRITISH J UNGER MANN IT 
( J. nemorosa j 
Ihe axillte of the perigonial leaves, also, and intermixed with the anthers, are frequently seen 
jointed, simple or slightly branched filaments (f. f. 11. 12); but whether they belong to the 
fructification, or are to be considered as some parasite (perhaps a Conferva), I am unable 
to determine. I have found them on British specimens, as well as on others, which 1 have 
received from Sweden. Had 1 not seen, in some of them, small branches, I should have 
supposed they had been abortive footstalks ; for their structure, in other respects, seems to be 
exactly the same. 
Female Fructification terminal upon the stems and branches. 
Calyx (f. 4) about a line and a half long ; at. its base narrow and cylindrical, but thence 
gradually increasing in width towards the extremity, which is half a line in diameter: 
it is remarkably incurved in its early state, but becomes erect when the capsule is 
protruded. The mouth is truncate and dentato-ciliate. In color and texture it resembles 
the leaves. 
Calyptra (f. 13) a white, thin, delicate membrane, of a pyriform figure, marked with 
rather large reticulations: the style is short and tubular. Of abortive pistilla (f. It) 
there are a few at the base of the calyptra, linear, greyish, longitudinally and 
transversely striated, their mouth slightly dilated. 
Peduncle short, scarcely exceeding twice the length of the calyx, white, cellulose, 
shining. 
Capsule oblongo-ovate, deep purplish brown, opening into four equal, lanceolate valves, 
which on their outer surface are longitudinally and transversely furrowed. 
Seeds and spiral filaments (f. 15) numerous, of a deep fulvous color: the former exactly 
spherical ; the latter composed of a double helix, of a greater length than is usual in 
the genus. 
Gemma (f. 7) are not uncommon on this plant, in the month of July, forming a compact 
granulated wart or tubercle, at the extremity of both the lobes of the leaves which are 
situated at the apex of the stems : at first, they are green ; in a more advanced period, 
brown ; and at length almost black, in which state the particles, of which they are 
composed, more readily separate, and are seen, under a high power of the microscope, 
to be oblong, pellucid, and by no means angular. 
Var. /3 (f. 16) scarcely differs from a, but in the deep purple color of the whole plant. In both 
kinds the figure of the leaf is subject to some slight variation, from obovate to rotundo-obovate. 
The lobules, in the lower part of the plant, appear occasionally to have the teeth nearly obsolete. 
The Var. y has a crisped and inelegant appearance, from the circumstance of t he lobes and 
lobules of the leaves being by no means conduplicate, but irregularly bent back, as is 
represented at (‘f. f. 1. and &). The color, too, is more inclining to a yellowish-brown. 
Var. S. (f. f. 17. 18) approaches, in the figure of its leaves, Jungermannia umbrosa, but may be 
distinguished by the greater proportional length and slenderness of the plant, in having its 
leaves more distantly placed, and in these being for the most part quite entire at the margins. 
The upper leaves, indeed, are slightly dentated. It is an extremely minute variety, scarcely 
attaining to half an inch in length, and is always found intermixed with a. The color of the 
stem and leaves is a very pale yellowish-green.
