I02 ALIEN FLORA OF BRITAIN 



Anthemis mixta, L. An abundant weed of cultivation 

 in some parts of the Mediterranean area. Once or twice 

 recorded among grain-sifting aliens in England. 



Anthemis ruthenica, Bieb. A weed of South-East 

 Europe, mentioned by Mr. Davey as a casual at 

 Penzance in Cornwall. 



Anthemis tinctoria, L. Native of Southern and 

 Central Europe. Recorded in many scattered localities 

 in England, in waste and cultivated ground. In some 

 cases its origin has been traced to imported Eastern 

 barley, in others agricultural seed has probably been the 

 cause of its appearance. 



[Arctium minus, Bernh. A native of Britain, but 

 almost always recorded from non-native habitats. It 

 is abundant, in consequence of its clinging burs, along 

 the tracks of men and cattle, and so has got to be 

 looked upon as a weed of roadsides, but it may also 

 be found wherever animals, domesticated or wild, 

 congregate, and often under perfectly natural con- 

 ditions, so that it may well be supposed to have existed 

 prior to man, and to be a member of our indigenous 

 flora.] 



Arnoseris pusilla, Gaertn. Native in sandy pastures 

 in a few parts of Central Europe, elsewhere a weed 

 of sandy cultivated fields, becoming very rare in the 

 extreme south and north. In British local Floras there 

 is no indication that the species is known except in 

 cultivated land in the south-eastern counties, and in a 

 few other isolated spots.
