PIab. — Growing intermixed with Campijlopm nfrovirens in 

 marshy places on the ascent of Cader Iclris, Merionethshire, to 

 the left of the bridle path to Tow}^!, from Dolgelly, about 1500 

 ft. IF. IL Pearson, April 1876. 



Extremely rare. Found on the Continent. 



Variety. Near Barmouth, Merionethshire. IF. II. Pearson^ 

 June, 1878. 



Obs. — Distinguished ivom Jiin^ennania capitata, Hook., by its 

 much larger size, more distant leaves, which are more delicate in 

 texture, and by the presence of stipules on the upper portion of 

 the stem, &c. 



I had some hesitation in adding this species to our list of 

 British Hepaticae, but as I sent good specimens to the late Prof 

 Lindberg, who replied, '' your Jiaig. mjcia, Nees, is correctly 

 named, no doubt left," I think it will stand good. 



I collected, near Barmouth, another form, where the stipules 

 are found all along the stem.
