In weed, or Vavilovian mimicry, the weed does not profit from encounters with man or his winnowing machinery; at best the weed is left, at worst it is destroyed.
Vavilovian mimicry bears considerable similarity to Batesian mimicry (where a harmless organism mimics a harmful species) in that the weed does not share the properties that give the model its protection, and both the model and the dupe (in this case people) are negatively affected by it.
