( J. polyanthos.J 
When found in a state of fructification, there are, perhaps, few individuals of the genus that 
may be so readily distinguished as the present j its exserted corolla, and its truncate and bilabiate 
calyx, affording characters no less decisive than remarkable. The leaves, also, seem very constantly 
to retain their subquadrate form ; and, though they may in some instances be as much emarginate 
as those of J. lieterophylla, yet still their general figure, and their being so much more frequently 
entire, furnish sufficient marks of discrimination. In addition to this, it may be further 
remarked, that the stipules, which in J. lieterophylla are much laciniated, are in J. polyanthos 
always entire. 
The Michelian figure above referred to is a tolerably accurate represention of our plant, 
indeed much more so, as it appears to me, than that cited by Dillenius (t. 5. f.5), which I have 
consequently omitted. The author last mentioned, if I may be allowed to judge from his own 
specimens, has described this species no less than three separate times in his Species Muscorum. Of 
these, his t. 69. f. 7. has always, though incorrectly, been regarded as J. viticulosa. The figure 
of Vaillant, bad as it is, bears a greater resemblance to the plant in question, than to J. asplenioides, 
under which species it has, in the writings of most Cryptogamists, found a place. Weis and Pollich, 
and even Linnseus himself, have been singularly unsuccessful in their description of this species ; 
nor does the fructification appear to be any where described with accuracy, till Schmidel published 
his valuable “ Dissertations ," whence Roth seems to have drawn his characters. Schraders 
J. pallescens, specimens of which have been communicated by the author himself to Mr. Turner, 
proves to be in no respect different from J. polyanthos.
