Colonist. Agrestal (parasitic). As the occurrence of 

 this species in any part of Britain, appears to be wholly 

 dependent on the cultivation or accidental sowing of flax, 

 its actual distribution must be artificial and changeable. 

 For example, I have once met with the species in North 

 Surrey, growing among less than a dozen plants of the 

 flax, by a public highway ; where, in all probability, the 

 seeds of the flax had been scattered by some bird-catcher, 

 and of course the locality was only a temporary one.
