or more, ered and Jhorteft in bogs and marfi>fs, 

 and of a dark green colour, their tops only red i 

 but proftrate and longeft in rivulets and tai- 

 cades, and of a dark or blood-red colour. 



The leaves in the adult plant arc roundifli, or ob- 

 tufely oval, convex on the vjpper fide, concave 

 on the under, denfely imbricated, embracing 

 the nerve at their bafe, and deflex'd in fuch a 

 manner over the nerve as to make the iTialks ap- 

 pear almofl: round, or at lelt fcmicylindrical. 

 Between thefe leaves, at their bale, on the un- 

 der fide, may be difcovered other lefler leaves, 

 or auricles, nearly of the fame Ihape with the 

 larger ones. 



In the young plants the leaves are round, plain, 

 alternately and more thinly fct, very variable m 

 fize, and without auricles. 



The ffucflifications we have never yet been able to 

 difcover. Dillenius and Micketi binii> iiave ob- 

 lerv'd farinaceous granules at the fummits of the 

 Italks, and Haller has feen the 'vagina and pe- 

 duncles of a Jungermannia growing from the 

 fame part, fo that there can be no doubt of its 

 being truly a Jungermannia, as the whole habit 

 gnd external appearance declare.
