BRITISH JUNGERMANNIiE. 
C J. minutissima. J 
Micheli had the honor of first detecting and describing this most diminutive species of the 
genus, which Dr. Smith has very aptly named minutissima. Italy and Great Britain are the only 
countries yet known to possess it ; though, with us, I think it can hardly be reckoned among the 
plantce rariores. 
In habit, as well as in the more important parts of fructification, (which are such as to furnish 
characters for a distinct genus) J. minutissima precisely accords with J.serpyllifolia, J. calyptrifolia , 
and J. hamatifolia : the leaves, nevertheless, will be found to differ essentially from those of the 
individuals now mentioned, in being altogether entire, or at most having so obscure an incision, 
that no one would consider the plant as belonging to the division “ foliis incequaliter bilobis." Indeed, 
it seems to hold an interemdiate place between that section and the one “foliis integris .” 
The stipules, though, on account of their small size, they are with difficulty detected and have 
not been noticed by any preceding authors, will, if caution is used, be found to exist throughout 
the whole length of the lower part of the surculus. 
Dillenius' figure and description of this species, as well as those of J. serpyllifolia , are, as 
noticed by that author, copied from Micheli.
