TANSY, Tanacetum vulgare L., contains a violent, irrit- 

 ant, narcotic poison, producing spasms and convulsions, 

 but is very rarely eaten by animals. It was introduced 

 into this country from Europe, and has escaped from gar- 

 dens in various places. 



It is a bitter and strong-scented herb, two to four feet 

 high, with tough parsley-like leaves. The heads, each 

 containing many yellow, tubular florets and few ray flor- 

 ets, are borne in dense flat corymbs.
