recorded in the Flora in error is the true native Black
Poplar. As pointed out by Edgar Milne-Redhead, this is
now a rare tree of the flood plains of rivers. Neverthe-
less, quite a few new records have been made for this tree
since the Flora was published. A few plants seem to have
been accidentally omitted from the Flora according to the
10km dots in the Atlas of the British Flora. So far we have
yet to trace the source of the records for Botrychium
lunaria (moonwort), for squares 99 and 22, Anagallis minima.
(Chaffweed) for 89, 80 and 99; Polygonum dumetorum for 88;
and Hypochoeris glabra for 59, 79 , 73, 88, 03, 02, & 03.
Several new plants have appeared on the scene since 1973.
Ludwigia palustris, Orobanche crenata, Hieracium salticola
and Crassula helmsii in 1976 and Lepidium perfoliatum in
1978, found on Norsey Island by Phil Luke. Nothing has been
seen of the Ludwigia in the wild since, although it survives
the winter well enough under a piece of polythene in my
garden pool, but Orobanche crenata seems to be well estab-
lished at Cranham although currently threatened by herbicide
spraying.
No spectacular additions have been made to the higher plant
list just recently, but several bryophyte species have been
added as a result of increased activity to complete the
mapping of our 10km squares for the new Atlas and to sort
out our Vice-county records for the forthcoming revision of
the Census Catalogues. Particularly exciting was the
the rediscovery of Zygodon forsteri yet another plant named
after Edward Forster and described new to science from Essex
material, found growing in its locus classicus - Epping Forest
on a beech tree in 1978. Other new additions are Sphagnum
capillaceum not seen in Vc 19 since the 1880's; Barbula
acuta new to Vc 19; Tortula ruraliformis, refound on the
dunes at Little Oakley where Sherrin found it in 1905;
Climacium dendroides found by Marcus Grace new for Vc 19
at Upshire, and last autumn on a British Bryological Society
visit to Warren Farm chalk pit, Lophozia personii in only
its 6th British location.
