2. EXHIBITS OF MIXED SPECIES. 
PLANTS OF BERKSHIRE. 
The exhibit consisted of twelve of the more uncommon plants 
found in the county of Berkshire, mounted as herbarium speci- 
mens. Chief among them were: — 
lllecebrum verticillatum L. Rediscovered at the edge of a 
sandy road near Wellington College, Berks, in 1949. Prior 
to 1891, this plant was recorded only from Cornwall, Devon, 
and the Channel Isles, so its discovery in that year near 
the damp sandy margin of a pool near Wellington College, 
Berks., was of singular interest. Druce in his 1919 Sup- 
plement to his Flora of Berkshire, records it again for that 
area, so it is most encouraging to know that during fifty 
odd years, this uncommon little plant is still holding its 
own. 
/ln.emon-e FidsatilUi L. Found on the Berkshire Downs, has sur- 
vived the most ruthless blasting from shell practice during 
the w'ar. The threat uoav is from a too ruthless picking 
and uprooting of plants which may ensue from a more 
easy accessibility to the slope on Avhich it grows. 
Hottonia palustris L. One of the plants which is unfortunately 
suffering from the vast sj’stem of drainage that is being 
carried out in many parts of England. It has gone from 
two localities in the Boiough of Reading, where formerly 
it flourished, but it still survives ivith diffculty in a pond 
near Grazelejq Berks. 
Fritillaria Meleagris L. Continues to flourish in some damp 
meadows by the River Loddon near Reading. 
Brosera rotundifoVm L. and D. lap-gifolia L. Found in several 
bog areas in the county. 
Lotus siliqwsus L. This forage plant of South Europe appears 
to be spreading on one or two chalk slopes.
