C us cut a suaveolens, Ser., has recently appeared in considerable 

 quantity on cultivated crops in South Wales. Onions and carrots 

 were the plants chiefly affected but the parasite seems almost 

 indifferent to the nature of its hosts for it had spread on to various 

 weeds, including Lotus conacuiatus, Are nana seryyUlfolia^ 

 Tri folium repens, Pastinaca sativa, and several grasses. 



The plant is a native of Chile but has been recorded from 

 various localities in Britain. It seems generally to have 

 occurred on lucerne, or at least in lucerne fields. In continental 

 Europe it has been recorded (under different names) from -many 

 localities. The synonymy is complicated but is given in full in 

 the paper quoted above. 



The seed from which the onions and carrots were grown in 

 South Wales was apparently obtained from several different 

 sources, mostly from well-known British firms. The dodder 

 may have been introduced with seeds of a previous crop, either 

 directly from Chile or from a European source. 



Another alien dodder, Cuscuta Tinei, Insenga, has been 

 recorded from South Wales. It occurred on experimental clover 

 plots at St. Pagan's, Cardiff. In this case the crop was raised 

 from Styrian or Bohemian seed. Quite recently it has been 

 received from Worcestershire growing on a crop of onions in an 

 allotment. C. Tinei is also probably of American origin and only 

 a colonist or casual in Europe. w. b. t.
