COMPOSITE 109 



Centaurea diluta, Ait. A native of Northern Africa. 

 A specimen exists in the British Museum Herbarium 

 gathered on waste ground in Upper Holloway. 



Centaurea iberica, Trev. A weed of cultivated and 

 waste ground from South-East Europe to Persia. Re- 

 corded as a grain introduction in one or two places. 



Centaiirea intybacea, Lam. A native of exposed 

 rocky ground in South-West Europe. Recorded as 

 a wool introduction at Tweedside, Kelso, by Mr. 

 Brotherson. 



[Centaurea Jacea, L. Apparently truly indigenous in 

 meadows in Sussex, as it undoubtedly is in Normandy 

 and Belgium. In other parts of England it has fre- 

 quently been recorded as an alien ; being so much more 

 frequent as an introduced plant, it has generally been 

 excluded from the native English list.] 



Centaurea melitensis, L. Native in dry stony places 

 in South-East Europe, and at the present time a not 

 uncommon cornfield weed of the Mediterranean area. 

 It has frequently been noticed in company with other 

 grain introductions in England. 



Centaurea montana, L. Indigenous in the woods of 

 Central Europe. Long cultivated in English gardens, 

 and occasionally noticed as an escape. 



Centaurea napifolia, L. Indigenous in the pastures 

 of Southern Europe. A specimen, gathered by Mr. 

 Arthur Bennett at Kelso, is preserved in the British 

 Museum Herbarium. It was doubtless a casual.
