HEPATIOE 



These are well represented in Derbyshire, which with its many 

 kinds of rock, its extensive moorlands, its range vertically from lowland 

 to subalpine, offers congenial habitats for a large number of species, 96 

 in all being so far known. Several species are peculiar to one or other 

 formation, which will be indicated in the appended list. Thus 5 species 

 are found on limestone only, 6 on limestone and Permian, 28 on grit 

 or sand and 5 on wet moorland or marshes. There are a few of special 

 interest owing to their rarity or their occurrence in the county being a 

 considerable extension from where they have been previously noted, 

 such as Hygrobiella /axtfo/ia, Hook., not found previously nearer than 

 Westmorland ; Lophocolea spicata, Tayl., hitherto known for Cornwall, 

 N. Wales and Scotland ; T'argionla hypophylla^ Linn., rare and local, the 

 nearest recorded station being in west Yorkshire ; Anthoceros punctatus, 

 Linn. The order and nomenclature followed here are those of Mr. 

 W. H. Pearson's Hepaticce of the British Isles.
