Hydroepizoochory

Under Hydroepizoochorie refers to the spread of diasporas as seeds , fruits , and whole plants rarely by adhering to moist surfaces. This type of spreading belongs to the group of sticky and Velcro spreading ( epichory ), which in turn belongs to the spreading strategy of animal spreading ( zoochory ). The plants are called watery or adhesive .

With this type of expansion, the expansion units typically have flattened shapes with a smooth surface. Adhesion takes place only through a thin film of water through adhesion ( adhesion ) to wet fur or plumage. If the seeds or fruit are dried later, they will fall off again.

Hydroepizoochory occurs, for example, in the following plants:

• Betula sp. (Birch): fruits
• Rumex sp. ( Dock ): fruits
• Asteraceae : fruit with pappus (flight organ)
• Lemna sp. (Duckweed): Complete plant
