Found on the Continent and in North America. 



Obs. — First discovered by Mr. Lyell in the New Forest in 

 1813, and published and figured in "Eng. Bot." under the false 

 name of Junfjeruianla Francisci, from which it is quite distinct, as 

 will be seen by reference to the description and figures of that 

 species. Nees was the first to recognise it as a new and distinct 

 species, but he appears afterwards to have doubted its claims to 

 specific rank, for he reduced it to a variety of Jungermania injlata 

 in his later works. As Dr. Spruce remarks, how such a con- 

 summate hepaticologist should have confounded them it is diflftcult 

 to conceive, adding : " It may suffice to contrast their chief 

 characters, which are, for C.puitans, the stem rooting by numerous 

 stout flagella; the branches, whether foliferous or floriferous, all 

 postical ; the longer, narrower, and more laxly-reticulate leaves ; 

 the constant presence of stipules ; the cladocarpous inflorescence ; 

 the tristichous female bracts, toothed at the base, the innermost 

 embracing the perianth ; finally, the lineari-fusiform, trigonous, 

 thin perianth. But in Jungermania injtata there are no flagella •
