the BBSUK Herbarium. They are listed in systematic order in accordance with
the nomenclature of the Atlas of the Bryophytes of Britain and Ireland (Hill et al.
1991-94). The entries follow the information given in the relevant BBS summer
Bulletins (publication year in round brackets) except where additional
information is available. In some cases the records are additional to those given
in the Flora of Essex (1974). These records confirm earlier gatherings
subsequently reported formally at some stage as being extinct. The presence of
an (*) in a column indicates that the species has already been recorded from
that vice-county at some time during the last 50 years. If the 18 or 19 appears in
round brackets the only record is more than 50 years old. Those species
annotated by ( + ) have been submitted to the appropriate BBS recorder and
been accepted but have yet to appear in the BBS Bulletin.
