 in the extreme east of the Mediterranean area, and 

 extending from there, as a cornfield weed, to Spain, 

 It has been gathered in one or two places in England 

 in connection with other grain-sifting aliens. 



Cephalaria transylvanica, Schrad. A cornfield weed 

 of Southern Europe. Once recorded from waste ground 

 in England, where it was doubtless the result of corn 

 introduction.

 and occasionally found in England as a straggler from 

 cultivation. 



Dipsacus laciniatus, L. Native of wet ground in 

 Southern Europe and the East. Recorded as a waste-

 introduction.]
