limitation. Linaria cymbalaria covered the walls at Great Ponton 
along with Parietaria. The latter is a favourite screen for Helix 
lapicida ; and the stones on the top of the walls for H. rupestris» 
Ononis spinosa was not uncommon on the Limestone and Chalky 
Boulder Clay, but the variety mitis was only detected on the 
former. The Origanum vulgare in the quarry near the Rise was 
typical; but the same plant in the wood was “ very hairy.” <A 
size variety (minutissima) of Papaver vhaeas, perfect little plants 
about three inches high, were very striking. Picris hievacioides 
was very conspicuous in Spitalgate hill quarry. Prunus tnsititia 
with very fine fruit, quite ripe, was ina hedge on the Chalky 
Boulder Clay at Great Ponton. ‘The green berried form of 
Sambucus nigra is found in hedges away from houses, on River 
Gravel, at Grantham on the Harrowby Road, The Valeviana of 
Ropsley Rise was mikanii as might be expected. A colour form 
of Veronica agrestis was most striking at Great Ponton. The 
flower was very large and bright pink, but otherwise the plant 
was typical. Vicia sylvatica covered acres of ground in the Rise 
while V. sepium seemed quite rare, “Many of our bettermost 
’ 
plants live in Ropsley Rise”’ as a native said in the true Lincoln- 
shire dialect. But the 3rd of October is too late for a full list ; 
yet if I were to report the result of all the notes taken, I should 
almost have to write a florula for this district. For instance. 
Primula acaulis and P. veris were observed, but the hybrid between 
them which is found here could not at this time be detected ; or 
the still rarer oxslip (P. elatior, jacq.), yet itis found here too—the 
great variety of this wood, the only spot for which it is recorded 
in Lincolnshire. It is always found on Chalky Boulder Clay 
wherever it is met in Britain; therefore it is only to be found in 
our eastern counties. A lovely example of ecology was seen on 
the 4th, on the Stroxton boundary of Great Ponton. Water in 
ponds is very scarce in this district, but a small pond on the 
Chalky Boulder Clay about 15 by 12 feet was hurriedly visited, 
as we were making our way back to catch the train. Planorbis — 
nautileus and Velletia lacustris were in evidence with less un- 
common fresh water shells, The flora noted being Potamogeton
