We have among our British Jungermanni@ two species (viz. 
J. viticulosa and J. trichomanis), which have ealyces pendent 
on the stalk; but then they are buried in the ground, or in 
the mosses and other plants among which they may happen to 
grow. In the present instance the calyx grows from the extre- 
Mity of an erect stem, or which is curved only, as it would ap- 
pear, from the weight of the fructification, and there is pendu- 
lous.. On the exterior surface of this calyx, near the mouth, 
is a cluster of pistilliform bodies, apparently covered by a mem- 
brane, and these are present at the same time with the perfect 
capsule. In the foliage and stems this plant has great affinity 
with J. asplenioides.
