Wind dispersal

To catch air currents and ride on the wind, wind-dispersed seeds can either be very light, such as dustlike orchid seeds, or have special shapes, such as parachutes, flutterers, helicoptors, cotton seeds, etc.

Use this device you can see how the wind-dispersal seeds work.
Parachutes: these seeds or single-seeded fruits (achenes) are attached to umbrella-like hair clusters at the top. The lightweight seeds can be dispersed by wind over long distances.
