with the closely related R. peltatus from
the other pond; with large flowers, pear-
shaped nectaries and rounded floating-leaf
segments. A small relict patch of Pignut;
beside the pond suggested that the arable
field had formerly been a flower-rich
pasture.
Most of Latton Park has been coniferized with
Thuja, Pinus, and Larix species, some patches
of Beech have been planted, and Birch has
appeared in some of the clearings. The
relict margins, however, support Hornbeam,
Oak, Ash and Hazel with some Aspen and quite
a lot of Maple. Huge Goat Willows occur
among the conifers along the drainage ditches
in the south. The rides are wide and quite
rich in herbs, such as Bugle, Primrose,
Angelica, Fleabane, Meadow Sweet, Creeping
Jenny, Hairy St. John's Wort, Thyme-leaved
Speedwell, Lady's Smock, Pignut, Germander
Speedwell, Greater and Lesser Stitchwort,
Marsh Bedstraw, Marsh Thistle, Carex flacca
and Carex otrubae.
The only ferns encountered were Common Male-
fern, Broad Buckler and Bracken, the latter
in a sector just north of Rundell's Grove.
A quick visit to Mark Bushes added a few
more species. Ragged-robin, Centuary,
Lesser Spearwort, and the mosses Eurhynchium
striatum and Calliergon cuspidatum. Eye-
bright (Euphrasia nemoralis) , formerly
recorded from here, was searched for and
seedling plants that might have been this
species (but could have been Odontites) were
located along the southern part of the ride
between Latton Park and Mark Bushes. In
the north-west sector of Mark Bushes a small,
almost silted up pond was covered by large
