Anemochory - Dispersal of Seeds

Seeds that are dispersed by air currents are usually light or are provided with special structures to help them remain air-borne for long periods. Since a large proportion of seeds are wasted, anemochorous plants usually produce a profuse quantity of seeds per plant.
