Found on the Continent and in South Africa. 



Oijs. — Distinguished from all other British Lcjeimcrc 

 bv the long acuminate distantly serrated antical lobe of leaf. 

 'J'liis hepatic has a most curious distribution ; it is found in lair 

 abundance on the gold-bearing reel's near the celebrated gold 

 mines at Tyn-y-Groes, in North Wales, also on quartz in 

 Borrowdale, at Ingleton in Yorkshire, not on tlie limestone 

 which is so abundant in the last-mentioned place, but on eruptive 

 rocks which arc exposed near the river. In a collection of 

 hepaticse made at Kynsna, a gold-bearing district in South 

 Africa, by Hans Iversen in 1883, specimens of this species were 

 found agreeing in every particular with our native one.
