The Conspectus includes the names of all the genera of 
which species are found in the British Isles, a total of 59 
g-enera, with 277 species described and figured in the 
Hepaticae of the British Isles. Sixteen of the above genera 
marked are not represented in Yorkshire so far as our 
present knowledge extends. Subsequent workers, who 
live in the localities amongst the hills, in which are fine 
moist glens with shelter, the habitats where these plants 
abound, may be able to make additions to the list of 
Yorkshire Hepaticae.
