( J. lanceolata .) 
BRITISH JUNGERMANNIiE. 
Male Fructification (f. 5) composed of anthers (f. 6), situated in clusters of two or three at the 
base of the cauline leaves, and most commonly of those that approach the extremity of 
the plant. They are quite exposed, as is the case with those of J. pusilla. Each is exactly 
spherical, minute, consisting of an exterior reticulated cuticle, and the olivaceous pollen, which 
is at length discharged from a ragged aperture at the extremity (f. 7). The footstalk, which 
is about the length of the anther, is white, pellucid, and transversely striated. 
Female Fructification terminal. 
Calyx (f. f. 2. 10) very large, compared with the size of the plant, full a line in length and 
one-third of a line in diameter, a little incurved, cylindrical throughout, or slightly 
incrassated upward : the apex itself is depressed and flattened, so that the extremity is 
nearly a plane surface, as wide as any part of the calyx, and in the centre of it is 
situated the minute, contracted, and slightly-toothed mouth. The whole is perfectly 
destitute of furrows. Its color and texture are not distinguishable from those of the 
leaves, except that the former occasionally vanes to a rich brown, appearing almost as 
if it were burnt. 
Germen (f. 8) ovate, of a yellowish-green color, terminated by a small hollow style. A few 
barren pistilla surround its base. 
Obs, The moie forward state of the fructification I have never had an opportunity of seeing. 
As well the figures here given, as the description, have been made from German specimens 
sent to Mr. Turner by Dr. Schrader and Dr. Mohr; and I am induced to represent the species in 
this work, rather with a view of calling the attention of the botanists of my country to what I 
conceive to be the true Jungermannia lanceolata of Linnaeus, than from a full conviction of its 
eier having been found in Britain. Micheli is the earliest author who has noticed the present 
plant, to which Dillenius’ t. 70. f. 10. has been referred by Linnaeus and almost every subsequent 
botanist; but I have, under the description of J. pumila, given my reasons for supposing that this 
synonym more probably belongs to that species. Haller, in his Hist. Stirp. Helv. t. m. p. 61. 
n. 1871, un hisder Jungermannia foliis pinnatis, avails, confertis, ex apice florifera, quotes Linnaeus 
as well as the two other authors just alluded to, but in his description he says, - folia paullhm 
' Ul 9 o U i‘vn Ct - m r aP T, e C ° ngeSta ’ P aull fimque incurva”, and in another place “ad Jungermanniam 
. 20. Dillemi (J. albicantem ) proximo accedit, sed differt foliis rotundioribus”; so that I am rather 
me need ° think that this great botanist has confounded the present species with one that I propose 
c.. mg J. obtusifoha which certainly approaches in many particulars to J. albicans. Weis has the
