BRITISH JUNGERMANNIiE. 
( J. scalaris.) 
preserved in Mr. Turner’s Herbarium, prove the J. scalaris of his Syst. Samml. to be the same as the 
one here represented, but still I dare not venture to quote Hoffmann and Roth’s plants without 
considerable doubt. It seems possible that the former may be our J. Trichomanis, but there is no 
mention made of the fructification ; and the calyx of J. scalaris ,' as described by Dr. Roth, appears 
rather to accord with J. crenulaia, which that writer probably confounded with it. No author, 
whatever, has remarked the stipules. 
J. scalaris is represented in English Botany under the name of lanceolata; but the unmagni- 
fied figures are taken from unusually luxuriant specimens, and are much larger than any individuals 
that have fallen under my own observation.
