BRITISH JUNGERMANNOE. 
The Leaves (f. 4), which are in general about half a line in length, are bifarious, alternate, 
for the most part so closely placed that their margins are slightly imbricated over each 
other, though, sometimes, as may be seen at f. 3, they are more distant, and have often 
a vacant space between each pair : they are patent or erect, rarely horizontal, through- 
out of an orbicular figure, on the upper side concave, below convex. The cellules are at 
the extremities of the leaf nearly quadrate and regular in figure, giving the edge a 
slightly marginated appearance; in other parts they are roundish, and so minute as to 
be seen only with a tolerably high magnifier : the color varies from a rich yellow-brown 
to a pale yellow-green, having the tips of the leaves, and especially of those that are 
nearest the extremity of the stem, not unfrequently tipped with purple. 
The Perigonial leaves 1 have not yet seen. 
The Perichcetial ones are confined to the short proper footstalk of the fructification, and 
are at its base roundish and entire, after which they become emarginate, and, the nearer 
they approach the calyx, the more frequently are they divided and laciniated; the 
uppermost are the largest, oblongo-ovate, and cut into five or six laciniated or toothed 
segments, their substance is more loosely cellular than that of the other leaves, their color 
a much paler and more yellow-green. 
Stipules are discoverable on this plant, but only on the shoots which produce the gemma; 
which are also furnished with leaves of a much smaller size than those of the main stem, 
though similar to them in shape. Each stipule is oblong or ligulate, obtuse, entire 
except in those that approach the extremity of the shoot, where they are emarginate. 
Male Fructification unknown. 
Female Fructification situated upon short proper footstalks, which are either lateral 
originating from the under side of the plant, or terminal. 
The Calyx is about a line and a half long, of an oblong figure, but attenuated at each 
extremity, extremely delicate, whitish, semipellucid (so as to shew the young capsule 
within), and slightly plicate ; the mouth contracted and a little toothed. The 
fructification I have not seen in a more advanced state. 
Gemma are found in great abundance and perfection in October and November, always 
upon elongations of the extremity of the plant, which are readily distinguishable from 
the rest of the stem by their smaller size, by their gradually tapering towards the apex, 
by the diminutive leaves, and still more easily by the stipules which are confined to them ; 
at least Mr. Lyell and myself have in vain searched for them throughout the rest of the 
plant. Both the terminal leaves and stipules are a little emarginate, and bear a few 
scattered gemmae, which are supported, in the form of little globules, sometimes single 
and sometimes two or three together, on the extremity of the shoot. Each particle 
is very minute, roundish, beset with a number of angles, pellucid, and of a pale yellow- 
green color.
