BRITISH JUNGERMANNIiE. 
( J. Hutchinsice) 
Obs. I am happy in being able to devote the first plate of a History of the British Jungermannice 
to a perfectly new and distinct species, and still more so in the opportunity it affords me of 
dedicating that species, one of the most beautiful with which I am acquainted, to its discoverer. 
Miss Hutchins, of Ballylickey, near Bantry ; a lady whose valuable communications on the sub- 
ject of marine Botany are already before the public in the Historia Fucorum, as well as in the 
British Conferva, and whose zeal and knowledge in the present genus of plants I shall 
frequently have occasion to notice in the progress of this little work. To her, through the 
kindness of my friend, Mr. Turner, I am indebted for many of the most rare and interesting 
species which will here be described. 
J. Hutchinsice was originally found, two years since, growing on a spot of ground which 
also produced J. trichophytla and Saxifraga Geum. It belongs to a small but very natural 
family (including J. dilatata and tamariscifolia) , differing from the rest of the Jungermannice 
stipulates in having a lohulus, or what, in compliance with the Linnaean terminology, I am 
induced to call auricle, which, in by far the greater number of the leaves, is rolled up into a 
small vesiculated appendage, and in having each of the spiral filaments composed of a single 
helix attached by its base to the extremity of the segments of the capsule, and enveloped in 
an extremely thin pellucid tube. From the two Jungermanniae last mentioned, the present 
species abundantly differs in a variety of respects, and may at all times readily be distinguished 
by its dark-green color, and still more certainly by the strongly denticulated margins of the 
leaves.
