In some countries this plant is cultivated 

 for the valuable painter's oil expressed from 

 its seeds, but in many parts of the United 

 States it is a very troublesome weed, for, 

 in addition to its exceeding prickliness, it 

 is protected by bitter, yellow juices, said 

 to be poisonous.

 or with few branches, usually very prickly 



but sometimes nearlv or quite unarmed.
