A BRYOPHYTE FLORA OF ESSEX 87
although these are useful for reference they contained no place
place names or dates. Many bryologists of the present time,
who either live in the county or pay it occasional visits, have
added to the list of records. Joseph Ross (1873-1962) knew the
location of some of the rarer species including Zygodon forsteri,
and he it was who first found Ptilidium pulcherrimum in Epping
Forest. In 1957, Dr F. Rose found the rare hepatic, Lophozia
capitata, on West Bergholt Heath. Dr F. Warburg (1908-1966),
with Prof. P. W. Richards, refound Plagiochila asplenioides in
Chaulkney Wood in 1952 and also recorded Eurynchium mega-
politanum near Beeleigh Mill in 1958. Messrs J. H. G. Peterken,
B. C. Wallace, C. C. Townsend and B. T. Ward have added to the
list. The most detailed work in the county recently has been
done by Eric Saunders (1912-1966). From 1958 to the time of
his death he added about 60 species to the Essex flora, including
Octodiceras fontanum, Bryum knowltonii and Pallavicinia
lyelii. The most recent work in the county has been accomplished
by Dr K. J. Adams, Dr A. J. Harrington, Messrs S. T. Licence and
P. J. Wanstall and this is continuing.
