THE FLORA OF WANSTEAD PARK DISTRICT. 127
moorland flora of the Forest is also to be found here on gravelly
ridges, such as Gorse, Goose-corn, Wavy Aira and Mat-grass.
On the north side of Bush road, sheltered by Grey Poplars and
Hawthorns, a colony of the small flowered Balsam, Impatiens
parviflora, has been established for thirty years or more. It is an
annual; with its broad dark green leaves and delicate pale yellow
flowers it looks rather exotic amongst our Forest flora. It is a
native of South Siberia, and has appeared as a weed in several of
the southern counties of England.
F. The Graveyard of the Society of Friends.
This land is surrounded by Bush Wood and has been enclosed
from the Forest for over eighty years ; before 1870 it was the
practising ground of an Archery Club. It is here awarded a
section to itself, since its turf retains some former flora which has
gradually disappeared from the adjacent Forest. Such plants
as Harebells, Petty-Whin and Creeping Willow occur amongst
Bedstraw, Mat-grass and Wavy Aira. An unusual and hand-
some perennial Spurge, Euphorbia virgata, native of South
Europe and West Asia, has become established in the turf. As
the graves increase in number this precious relic of Forest flora
is gradually encroached upon, and most of it will eventually
disappear, but the fine old oaks and thorns that help make a
sheltering screen to the grounds will remain.
I am much indebted to my friend, Mr. A. B. Jackson, for
his assistance in measuring the trees in Bush Wood and the
Warren grounds.
In conclusion I may add that I well remember Butomus
umbellatus L. growing in abundance along the banks of the
Boating Lake in the Park, and Carex Pseudo-cyperus L. with its
drooping tassels of fruit by the Perch Pond in earlier days, but
they have now disappeared. Lemna gibba L. was also very
abundant in Perch Pond, and Oenanthe Phellandrium Lamk. was
not uncommon along its shores until recently ; it is probable
that careful search would show that they still survive there.
