A HISTORY OF CORNWALL 



attention to this group of plants for many years, and his herbarium, 

 in the form of a large album, now in the museum which Mr. W. E. 

 Bailey has given to his native town, Mansfield, is probably the most 

 perfectly mounted collection of British Hepaticas ever made. From the 

 delicacy of their fronds and the ephemeral nature of their delicate 

 hyaline fruitstalks, they rarely retain their natural appearance in herbaria ; 

 but Mr. Curnow's specimens are almost as perfect and recognizable as 

 artistic illustrations in printed works. Many of them were culti- 

 vated on damp slate so as to free them from the soil, which adheres closely 

 to their delicate rootlets under ordinary circumstances. No such care- 

 fully mounted collection exists even in our national herbaria. The 

 classification and nomenclature in the following list are those of Pearson's 

 Hepatic cf of the British Isles. 



The Hepaticse are well represented in Cornwall so far as the sub- 

 alpine species are concerned, but alpine species and those favouring lime- 

 stone are noticeably absent from the list. The rarer species are indicated 

 by an asterisk prefixed to the name. Common species omitted from this 

 list are fourteen in number.
