stem, furnished with one or two rather large and spiniform processes or teeth, and, at 
the extremity, divided by an acute sinus into two serrated lobes. At the lower base of 
the leaf, and on the under side of the stem, is the auricle, an ovate, inflated, pouchlike 
appendage, about one-fourth of the size of the leaf, which it exactly resembles in texture ; 
both having extremely minute, yet distantly-placed, cellules (f. 5). The color of the 
leaves is a fine purple towards the extremity of the plant, but becoming browner as it 
approaches the base; that of the auricles a greenish brown. 
The Fructification is altogether unknown to me. 
The Lin nocan Mnium Jungermannia is, in all probability, the same as the plant here represented, 
which has, nevertheless, no affinity with the plant referred to in Micheli's Nova Genera Plantarum, 
by the illustrious Swede, under that species ; that, as I have already had occasion to observe, being 
nothing more than a purple variety of J. nemorosa. Ray’s plant is surely the same as ours ; and 
Dillenius’ figure is too accurate to be mistaken, although I did not observe the species in his 
herbarium at Oxford. The Hallerian synonym I can quote but doubtfully; but Weis, who first 
adopted the name of “ cochleariformis," has described the species with considerable accuracy. 
Neither this, however, nor any other author, seems to have been acquainted with the fructification; 
unless, indeed, Weber may be supposed to have been so, who still merely says of the plant, 
that “ Maii mense profert vaginas terminales, surculis concolores, cylindricas.” 
Dr. Smith has made a remark upon J. cochleariformis, which I have not been able to verify 
by my own observation, that “ the younger plants have flatter leaves, and are without the auricles.” 
On the contrary, in all the specimens that have fallen under my observation, the leaves have been 
very convex, and the auricles sufficiently conspicuous.
