 Edgware Koad Station of North London Eailway, 1866 or 1867; 

 Warren. Site of Exhibition of 1862, South Kensington. We have 

 seen the plant nowhere native in the county ; Merrett may have 

 mistaken small plants of 341 E. canadensis for this at Parson's 

 Green. The S. Kensington plant is a large form with a white pappus 

 {E. corymbosus, Wallr. ?).

First record: Tancred Robinson, 1690. A North American species. 

 Thoroughly naturalised, and indeed one of the commonest weeds in 

 and about London, especially in the dry sandy western suburbs, and 

 extending up the Thames valley to Hampton. An American writer 

 states, but without giving any reference or additional particulars, that 

 this plant ' sprang up in Europe 200 years ago from a seed which 

 dropped out of the stuffed skin of a bird.' Marsh, Man and Nature, 68.
