LEGUMINOS^ 59 



Medicago orbicularis, All. A rather common corn- 

 field weed of Central Europe, Southern Europe, and the 

 East, which has frequently been recorded in connection 

 with other grain introductions in England. It is appa- 

 rently a native of the grassy hills and seashores of the 

 Mediterranean region. 



Medicago rigidula, Desr. A weed of Southern Europe. 

 Occasionally found as a casual in waste places in Britain. 



Medicago sativa, L.^ Common, and doubtless wild, 

 in Northern Africa and Western Asia. In Europe, 

 more or less obviously, a relic of cultivation. In Britain 

 it is commonly cultivated as a field crop, and persists 

 for many years after sowing, sometimes remaining after 

 other signs of cultivation have disappeared, and so 

 looking like a native. 



Medicago scutellata, Mill. Native of pastures in 

 Southern Europe. A widely distributed cornfield weed 

 of the Mediterranean region and the East, and several 

 times recorded as a grain introduction in Britain. 



Medicago Soleirolii, Duby. Native of the mountains 

 of Southern Italy. It was recorded by Dr. Leitch among 

 grain aliens at Silloth, in Cumberland, and it is so 

 distinct that an error of determination is unlikely. It is 

 difficult to understand the presence of such a species 

 under these conditions, either there or in Southern 

 France, where it is also said to be naturalised in one 

 place. 



Medicago sphserocarpa, Bert. A Mediterranean weed, 

 recorded as a casual near Tunbridge.
