S. Vaccaria, L. {Vaccaria vulgaris. Host.) Cow-Herb. 



Seldom plentiful, but reported at many places throughout the state. Mr. Leiberg 

 writes : "This is becoming a common weed in the grain-flelds of Blue Earth county, 

 where the farmers call it 'cockle', and complain very much of it. It will doubtless be- 

 come as plentiful as the true cockle (Lychnis Githago). Most of the seeds are just 

 small enough to pass through a wheat-screen, and they can thus be separated ; but, 

 as the largest seeds will be left in whenever the grain is cleaned, the result will be that 

 in time, through this process of selection, the seeds can no more be cleaned out of the 

 wheat than true cockle."
