 It has been noticed with white flowers at Cothill. The leaves are of' 

 a paler yellow tint than those of any other British species. This plant 

 was especially abundant in the dry springs of 1893-4. It reaches its 

 maximum of frequency on the Coralline Oolite, but is also found on 

 gravelly or sandy soils, especially when these are made up of calcareous 

 debris. 



Buckinghamshire appears to be the only one of the neighbouring 

 counties for which G. rotund if olium is not recorded.

 First record. Geranium columbinum maximum foliis dissectis, on that part 

 of Botley Causey next Oxford in great plenty, Plot, Nat. Hist, of 

 Oxford, 1677. (The locality was probably in Oxfordshire, but the 

 plant extends into Berkshire in the vicinity.) Another early 

 record is that of Geranium Columbimmi majus foliis imis lotigis usque ad 

 pedicidum divisis. In agris et pratis Oxonium circumjacentibus 

 a Jacobo Bobert juniore detecta, Morison, Hist. Ox. ii. 511, 1680. 

 The plant is too generally distributed to need the enumeration of 

 special localities ; next to G. molle it is our commonest species. White- 

 flowered plants have been noticed near Moulsford. 

 G. dissectum occurs in all the bordering counties.
