ii8 ALIEN FLORA OF BRITAIN 



[Inula Helenium, L. Native in meadows and bushy 

 places from Southern England and Spain to the Altai 

 Mountains. It has been recorded from all parts of 

 England and Wales, and in a few of its localities it is 

 declared by local botanists to be undoubtedly native. 

 In most of its stations, on the other hand, it is with 

 equal certainty declared to be a relic of cultivation. 

 In weighing these contrary opinions, help is naturally 

 looked for from a consideration of its history and its 

 geographical distribution. Both these favour its native 

 status, for it was known to the earliest botanists as 

 growing spontaneously in the country, and its range 

 on the Continent reaches the north coast.] 



Inula viscosa, Ait. Native of sandy river banks in 

 Southern Europe. Once recorded as growing on 

 ballast at Cardiff. 



Iva xanthifolia, Nutt. Recorded by Mr. Hume 

 among the introduced aliens in the neighbourhood of 

 Par Harbour. 



Lactuca Scariola, L. A plant of waste ground in 

 England, as it is in the greater part of Europe. Where 

 it is known in natural habitats the writer has been 

 unable to discover, but it seems certain that it cannot 

 be claimed as a native of this country. 



[Lactuca virosa, L. Native of woods and stony 

 and sandy places on the Continent, and probably 

 also in the South of England. In most of its English 

 stations it is said to be a weed of roadsides and waste 

 ground.]
