BRITISH J UNGER MANN HE 
( J . Sphagni J 
It is to Charles Lyell, Esq., of Bartley Lodge, that the botanical world is indebted for most of 
the above interesting particulars relative to the fructification and gemms of Jungermannia 
Sphagni. The industry and researches of this gentleman in the tribe of plants which are the 
subject of this publication, have been unwearied, and his success (as these pages will amply 
testify) has been commensurate with his zeal. Till very lately Mr. Dickson’s original specimen, 
from which his figure and description were taken, was the only one that had been found in 
fructification; and I exceedingly regret that it has not been in my power to add to the 
accompanying plate, figures of the specimens in that state which Mr. Lyell has so liberally 
communicated to me. They will, however, appear in a supplementary number, for which they 
are reserved. 
It is almost needless to point out the discriminating marks of a species so distinct as the 
present, and I shall content myself with observing, that the large radicles, and the peculiar form 
of the calyx, together with its proper footstalk, are, I believe, confined to this species. The leaves, 
also, though they bear no small resemblance, in general outline, to those of a new Jungermannia, 
which I propose calling J. Taylori, as well as to some of the leaves of J. anomala, and to those of 
J. sealaris, may always be known from those of other Jungermannia;, by the firmness of their 
texture, and by the remarkable smallness of the cellules, combined with their general shape. 
Although Jungermannia Sphagni , in a barren state, has been found in various parts of 
England and Ire 1 and, yet the continental botanists seem to be scarcely acquainted with it. 
Hoffmann, indeed, Roth and Lamarck, have noticed it in their respective works, but they have 
copied, almost verbatim, the description of our English cryptogamist, Mr. Dickson. It is 
certainly found in Sweden, whence I have received specimens from Dr. Swartz.
