By Wind because it has a wing-like structure
Splitting Open
a flower
it is done by animals
Wind dispersal
who would know we are not geeks are we hahaha
no
dispersal of seeds and polination in duckweed
Animals
By splitting/explosive method.
The dispersal method for bird's nest fern is either by wind, animals, or grow where they fall.
Most species of shorea have seeds connected to propeller type wings. These wings make it easy for the wind to catch and disperse the seeds. Water can also be an important factor in dispersal as in rivers and run-off.
Wind is the best method of seed dispersal.
