When seed dispersal is done through external means: Wind dispersal is one process of allochory which can take on one of two primary forms: seeds can float on the breeze or alternatively, they can flutter to the ground.

The classic examples of these dispersal mechanisms of allochories include dandelions, which have a feathery pappus attached to their seeds and can be dispersed long distances, and maples, which have winged seeds (samara) and flutter to the ground.
