 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. JUNGERMANNIACE^E Frullania *fragilifolia, Tayl.
