( J.anomala. ) BRITISH JUNGERMANNIiE. 
Orbicular leaves are sometimes found throughout the whole length of an individual p 
but it more frequently happens that those at the base of the stem alone are of this shape, 
and that thence they become more ovate and acute as they approach the extremity: 
at the extreme apex, three or four leaves (before their expansion) often embrace each 
other so closely as to form an oblong acute mass, which may, without due examination, 
be readily mistaken for a calyx.— It is to be observed that the upper leaves in 
gemmiferous plants are often jagged at the point, or cut into two, thiee, or more unequal 
teeth. The cellules are throughout remarkably large in proportion to the size of the 
leaf, and are conspicuous to the naked eye, when the plant is in a dry state, by a 
punctated appearance; they are of a roundish form, except at the bolder, where they 
approach more nearly to quadrate (but scarcely in so regular a manner as to cause a 
marginated appearance upon the edge), and in the ovate leaves the cellules are of a more 
oblong figure. The color is generally a rich but rather pale yellow-brown, the apices of 
the leaves often slightly tinged with purple. 
Stipules small, subulate; one to each pair of leaves. 
The Perigonial Leaves differ in no other respect from the rest, than in having a ventricose 
base near the insertion upon the stem, where the 
Male Fructification is situated. Anthers small, spherical, reticulated. Footstalk, or Filament, 
white, striated transversely. 
Female Fructification at present unknown. 
Obs. Gemnuc are found on this species throughout the greatest part of the year, but 
most plentifully in the autumn. They foim two or three rather compact spherical clusters, of a 
pale yellow-green color, at the apex of the terminal leaves, and some below them also bear them 
at their points, either in small globules or loosely scattered. Each particle is semipellucid, 
and roundish, but angular. It may be well to remark that the leaves, which support them, seem 
to be injured, and have their apices as it were corroded and jagged, after the dispersion of the 
Gemmae. 
J. anomala was first discovered by the Rev. R. B. Francis, who has for many years remarked 
it in his immediate neighborhood. I have also received it from other parts of England, as well as 
from Scotland and Ireland, but always without any of its parts of fructification, except the 
Anthers, which have once been found by Mr. Lyell. Dr. Swartz, too, has sent it to me from 
Sweden, gathered along with J. Sphagni. 
The most striking features about this plant are the uncertain form of the leaves, varying, 
even on the same individual, from orbicular to ovato-acuminate, and the large size of the cellules 
in proportion to that of the leaf. In the former particular it has no affinity with any species with 
which I am acquainted, and in the latter it bears a resemblance only to J . Taylori, which also has 
stipules agreeing very nearly in figure with those of the present species. In both they are
