Hab. — An alpine species, growing on rocks or amongst mosses; 

 very rare. Ehonas Hill, Shetland, Dr. GreviUe. 



Found on the Continent and in North America. 



Obs. — This extremely rare British species is not likely to be 

 confounded with any other native hepatic. From Jun^. minuta, 

 Crantz, its nearest congener, it is distinguished by its robustness, 

 the more obtuse lobes of the leaves and its dentate bracts ; from 

 Jung. Kunzeana, Hiib., by the absence of stipules, &c.
