PREFACE.
I he splendid monograph of “ British Junger-
mannim” published by Sir W. J. Hooker, in 1816,
was the first independent work on the Hepaticse published
in this country, although many species were
figuied in Smith and Sowerby’s English Botany,
1790-1814. After that time no attempt was made
at the publication of a separate work until 1865.
During the interval the Liverworts were included in
general Floras, such as Hooker’s English Flora, Vol.
V., in 1833, but notably in Gray’s Arrangement of
British Plants in 1821, and in the latter several new
genera were proposed, which were wholly ignored
down to most recent times. In the year 1865 a
small and unpretending little work was issued
under the title of “ Science Gossip ; easy guide to
the study of British Hepaticae,” which included
brief descriptions of all the species known to date.
