Vavilovian mimicry that lives with flax". Weeding of the adult plant is impractical; instead they are separated based on properties of the seed. This is done by a winnowing machine, which in this case acts as an inanimate signal receiver.

Another example is rye ("Secale cereale"), a grass which is derived from wild rye ("Secale montanum"), a widely distributed Mediterranean species.
