These are the only two known stations. 



Obs. — The rarest, and one of the most beautiful and finest of 

 our British Hepaticse, discovered on Brandon Mountain, South of 

 Ireland, by Dr. Taylor in 1813, and although repeated attempts 

 have been made by other botanists, no one, except Dr. Taylor and 

 Mr. Mitten, has been so fortunate as to meet with it in Ireland ; 

 and as only few specimens were known to exist in herbaria, most 

 botanists had to be content with the description, and say with 

 the late Dr. D. Moore in his Report on the Irish Hepaticse : '^ I 

 know nothing of this plant further than the quotations transcribed 

 testify." 



However, in 1898 Mr. Symers M. Maevicar found the plant 

 in Scotland, and in the following year I had the good fortune of 

 being taken to its habitat by him. 



I add the following notes from his interesting Hepatica3 of 

 Moidart, "Journ. of Bot." Aus^. 1899: "Liable to be overlooked
