Nelumbo fruit is the etaerio of achenes which is embedded in spongy, lightweight thalamus.
Anemochory is seed or fruit dispersal by wind. Fruits which are dispersed by anemochory should be lightweight and have some morphological characteristics as wings, hairs. But Nelumbo fruit is a type of aggregate fruit and does not possess any morphological characteristics.
