BRITISH JUNGERMANNHE. 
as uncertain as possible in number, length, and situation, being all on the same 
plane ; these are mostly simple, but sometimes again beset with a tew short, simple 
ramuli. 
Leaves (f. f. 3. 4) rather closely imbricated (at least in a.) over the whole upper 
side of the stem, bifarious, somewhat two-lobed, having the upper lobe by far the 
largest, and the sixth, or sometimes even the fourth of a line long, horizontal, ovate, 
very slightly convex above, the base beneath ventricose, where the lesser lobe arises, 
which, perhaps, might with more propriety, be called a dilated and remarkably in- 
voluted portion of the margin : taken altogether, the leaf very correctly resembles a 
specimen of the Helix auricularis, by which comparison its figure will be better 
understood, than could be the case by means of words. The texture is delicate ; the cellules 
large, roundish. The color a pale yellow -green. 
Perigonial leaves (which I had not seen till it was too late for them to be represented 
on the plate) closely imbricated upon short ramuli, forming ovate compact masses, like 
those of J. platyphylla. They are ventricose at the base, but the lobule is less involute 
than that of the cauline leaves. 
Perichatial leaves (f. f. 6. 12. 13) of quite a different figure from any of the rest, being 
much larger, and divided deeply into two oblongo-ovate obtuse and slightly convex 
lobes, which closely embrace the calyx : the upper one is about thrice the size of 
the lower. 
Stipules (f. 5) roundish, plane, cleft above a third of their length into two sharp and 
equal segments, whose sinus is rather acute, extending about one-third of the length 
of the stipule. 
Male Fructification : a single Anther is situated in the axilla of each perigonial leaf. It 
is reticulated, spherical, and terminates a short, white, transversely striated footstalk. 
Female Fructification lateral and axillary. 
Calyx (f. 6) about twice the length of the leaves, widely obovate, at the base cylin- 
drical, thence gradually becoming of a larger diameter towards the extremity, furnished 
throughout its whole length with five longitudinal sharp angles. The mouth small and 
protruding into a short tube. 
Calyptra ({. f. 7- 8) extremely thin and delicate, so that the young capsule may be seen 
within it. The reticulation is large, and the areolae oblong; the style, with which it 
is terminated, is long, tubular, and slightly expanded at the mouth. 
Peduncle about twice the length of the calyx, wholly composed of a number of parallel 
tubes, all of equal length, which are placed in distinct bundles, so that by the ter- 
mination of the several parcels, are formed distinct transverse lines, dividing the footstalk 
into several joints. In a dry state, these joints are bent with much regularity to the 
right and left alternately, and give the peduncle a zigzag appearance. 
Capsule (f. 9) perfectly spherical, white, beautifully marked with large and roundish 
reticulations ; so transparent, that the green seeds may be seen through it, and the 
extreme edge forms round these a white ring or limbus. It opens into four equal 
valves, which, extend only half its length (f. 9), and always preserve their vertical 
direction, never becoming reflexed, or even patent. 
The spiral filaments (f. f. 9. 10) are composed of a double helix, slightly twisted, en- 
closed witliin a large semipellucid tube, much expanded at the mouth. The seeds 
(f 11) are few in number, large, oblong, somewhat angular, of a dark green color -
