 The localities in the Isis, Ock, Pang, and some of those given under 

 the Kennet district, represent plants of garden origin, some of them 

 being var. fl(yre pleno. 



In some parts of the Kennet, and in many localities in the Loddon 

 district, the Pyrethrum has the appearance of being native, since it is 

 found in old hedgerows in considerable quantity, often far removed 

 from gardens or houses. 



C. Parihenium is recorded as a moi'e or less naturalized plant from all 

 the bordering counties.
