58 ALIEN FLORA OF BRITAIN 



[Medicago denticulata, Willd. An undoubted native 

 of sandy pastures near the sea in various parts of 

 Europe, including Normandy and South-East England^ 

 In Britain, however, it is far more common as a weed in 

 cultivated and waste places.] 



Medicago laciniata, Mill. A cornfield weed of the 

 Orient, which has occurred in connection with barley- 

 sifting aliens, showing a tendency in one locality to 

 establish itself in the turf. 



Medicago littoralis, Rhode. A native of sea sands 

 on the shores of the Mediterranean Sea. It has been 

 recorded at Cardiff, to which port a large quantity of 

 shipping comes in ballast, and was doubtless introduced 

 in the ballast of a ship from the south of Europe. 



[Medicago maculata, Willd. Native of dry pastures 

 in various parts of Britain, but more often recorded 

 from waste ground roadsides, &c., to which it has been 

 carried by human aid in consequence of its clinging 

 fruit.] 



Medicago marina, L. A conspicuous feature of the 

 vegetation of parts of the Mediterranean shores. It has 

 been recorded at Cardiff, having been introduced, most 

 probably, in ships' ballast. 



[Medicago minima, L, A weed of dry sandy 

 places in Europe and Western Asia. It has been re- 

 corded from several localities in the south-east of 

 England, and may well be native there, as it is ia 

 Normandy. Elsewhere in Britain the records are all 

 in connection with corn, wool, or ballast introductions.].
