BRITISH JUNGERMANNI/E. 
the leaves are more distantly placed, very small, and very unequally lobed. The texture 
is rigid, especially in a dry state; the cellules small, roundish. The color a yellow - 
green, much inclining to olive or brown. 
Peri gonial leaves, more concave than the rest, and even ventricose at the base ; but in other 
respects like them : in general, they are only seen near the extremity of the stem. 
Perichatial leaves (f. C) large, roundish, divided into two, or, not unfrequently, three, 
acute lobes or segments. When only two segments, I have observed a small lobe 
towards the base; probably the rudiment of a larger one. Their color is paler than 
that of the cauline leaves, and they are of a more delicate texture. 
Male Fructification. Anthers, situated in the axillae of the perigonial leaves, two or three 
in each, spherical, reticulated: the footstalks short, white, transversely striated. 
Female Fructification terminal. 
Calyx, at first globose (f. 7), and wholly concealed by the perichaetial leaves; at length 
becoming obovate, or even obovato-oblong, three-fourths of a line long, a little plicate 
above; the mouth contracted, and fringed with very minute teeth. 
Peduncle half an inch long, white, cellulose. 
Capsule oblongo-ovate, of a reddish brown color, striated longitudinally and transversely, 
and opening into four, equal, lineari -lanceolate valves. 
Seeds and spiral filaments fulvous brown, the former of a spherical form, smooth; the 
latter composed of two short and closely twisted helices. 
Obs. At Isla, on the 21st of July, Mr. I .yell discovered Gemmae upon this species, bearing 
a considerable similarity to those of J. infiata, (as represented by Schmidel) and those of J. excisa ; 
but far less compact than the latter, and more confined to the terminal leaves than appears 
to be the case with the former. They are of a red color, minute, angular, pellucid, presenting 
no internal organization, collected into small, though by no means compact balls, at the apex 
of each lobe of the leaf. 
The Dillenian plants which came from Greenland, and are preserved in the Herbarium at 
Oxford, though exactly agreeing with the specimens here figured, as well as with others wdiich 
have been given me by Mr. Dickson, are, nevertheless, very unlike the figure and description in the 
Historia Muscorum, and, indeed, so much so, that it seems scarcely possible that these latter 
could have been made from those individuals. The fructification of J. minuta was entirely unknown, 
till detected by Miss Hutchins and Dr. Taylor, in Ireland, and, subsequently, in Scotland, by 
Mr. Lyell, who, alone, has found both anthers and capsules. 
1 bis is an elegant and extremely well defined species, and has a peculiarly neat appearance, 
from the circumstance of the leaves being most regularly disposed, all placed in a nearly horizontal 
direction, and, as it were, in a pinnated manner. In color, it nearly approaches some of the 
states of J. infiata; and some of the leaves bear a considerable affinity witli that species, but 
they have the sides always conduplicate, and the points more acute, The lower leaves, being
