COMPOSITE 115 



Galinsoga parviflora, Cav. Native of rough, marshy, 

 and stony ground in Central and South America. It 

 was first noticed in Europe at the beginning of the 

 nineteenth century, and it is now locally abundant in 

 different parts of the Continent and of England. It is 

 particularly abundant about London. Its occurrence 

 among corn-siftings suggests that the introduction of 

 American wheat may have been the cause of its appear- 

 ance in Europe. 



[Gnaphalium luteo-album, L. Apparently native on 

 the Continent, up to the north-west coasts, and extend- 

 ing to Jersey and Guernsey. Though it has usually been 

 regarded as a casual in England (and may be so in many 

 cases), records such as Mr. Linton's in the Botanical 

 Exchange Club Report for 1882, where he describes it 

 as well established, if not native, may well be admitted 

 as indigenous ones. Mr. Britten, in Joiinial of Botany, 

 1900, p. 520, gives other reasons for considering it in- 

 digenous.] 



Grindelia squarrosa, Dunal. A native of the prairies 

 of North America, and spreading rapidly as a weed of 

 cultivated ground in the United States. Several times 

 recorded in England in connection with the siftings of 

 imported grain. 



Guizotia abyssinica, Cass. A bird-seed introduction. 

 The species is one of the oil-producing plants of 

 India, and its seeds are evidently used for making 

 up packets of bird seeds. Several times recorded in 

 England and from other parts of Europe from waste 

 ground.
